In October 1871, a fire in Peshtigo. WI. killed more than 1,500people and burned 1.2 million acres.The Peshtigo Fire occurred in thesame month as the infamous Chicago Fire. But while everyone hasheard of Mrs. O'Leary's cow, fewhave heard of the Peshtigo fire inwhich four times as many peopledied.
Ancient history? Not so!The 1985 wildland fire season
was the most severe of this century.By the end of the fiscal year. over83,000 wildfires had burned almost3 million acres, destroyed or damaged in excess of 1,400 structuresand dwellings, caused the deathsof 44 civilians and firefighters. andcost the Federal, State. and localfire agencies and private industryover 400 million dollars in firefighting costs. Damage estimates to natural resources and property are notavailable, but probably run into thehundreds of millions of dollars.
The Southern States east of theAppalachian Mountains from Floridato Virginia, parts of New England.Idaho. Nevada. and central California were especially hard hit by wildfires. National mobilization wasneeded in the Western States andin the South to cope with wildfires.During the first week of July. atotal fire mobilization of over20.000 Federal and State firefighterswas committed to fires in 13 Western States, including massive fires inCalifornia, Idaho, Oregon, and Ne-

vada.The loss of property was the
worst since 1871 when the PeshtigoFire destroyed entire communities.Major losses of buildings occurredin Florida, North Carolina, and California, but reports of structurelosses have also come from Washington. South Carolina, Oregon,and New England. The number ofstrnctures saved by wildland firefighters is not known, but wildfirereports routinely listed "structuresthreatened" in daily status reports.Because protection of property andlives took priority, natural resourcelosses increased when fire forceswere diverted to protect structures.
Last year's loss in lives and property is part of a developing trend.A major population shift from urbanto suburban living in the years sinceWorld War II has greatly expandedwhat is now called the urban/wildland or woodland home environment-the zone where people arein contact with the wildlands forreasons not related to timber orother traditional forest uses. Although this trend has increased thegeneral population's appreciationfor the amenity values of forests.it has also greatly increased thenumber of primary residences, second homes, and retirement homeslocated in forests and brushlands.Vast areas of the United States contain high-value properties intermingled with flammable native vegetation.
Structural fire losses are increasing dramatically as more peoplebuild and live in proximity to flammable plant communities. Majorloss of life is possible-in fact, inevitable. The problem is not, asis often believed, one uniqueto southern California. The extensionof residential and commercial development into areas with high firerisk has been noted throughout theNation-from the Georgia Piedmontand the sand plains of central Michigan to the Rocky Mountain foothillsnear Denver to northern New England.
Although current fire managementpractices make it unlikely that fireswill ever again reach the huge proportions of those in 19th-centuryAmerica, the risks to life, property,natural resources, and economicwelfare are much higher today thenever before. Huge fires are not required for catastrophic losses in themodern wildland/urban interface.Even small fires can be killers--three homeowners died when an8-acre fire swept their BaldwinHills, CA. subdivision. Fire management must change in order to betterprevent and suppress smaller, fastmoving single and multiple fires asa wildland/urban interface continuesto expand. This change must occurnationally.
The task of protecting lives andproperty from wildfires in the wildland/urban interface poses one ofthe most critical and elusive prob-

Losses of property and life as a result of fires in the wildland/urban interface have been increasing dramaucaliy in recent years.
lems faced by wildfire protectionagencies. Wildfire protection agencies have broken the problem downinto several parts:
• Fire managers are unable toreliably predict erratic fire behaviorin mixture of structures, ornamentalvegetation, and wildland fuels characterizing the interface. Physicalfuel properties and moisture relationsin these areas are not well understood, as they are governed by bothnatural and human-caused phenomena. Possible relationshipsamong building and landscaping location, design, and construction,with respect to terrain and otherstructures, add to the complexityof fire behavior. For example, spotting (fires starting from flying em-
4
bers) is especially difficult to forecast due to the diversity of firebrandmaterials and unusually complexwindflow patterns. Yet, spotting isthe chief cause of structural fireignitions in wildland/urban areas.
• Use of prescribed fire for hazard reduction (fires purposely setto remove undesirable vegetation)is made difficult by legal, political,and environmental concerns. Liability for damages to intermingledprivate holdings is a significant deterrent. In many cases, the veryreason for living in the interfaceprecludes the use of fire. Nonetheless, means must be found to manage fire hazards in the interface,while maintaining or enhancing desired environmental and economic
values.• Many property owners are un
aware of the wildfire threat, andfire safety ordinances and buildingcodes are frequently inadequate,unenforced, or disregarded. A quintessential example is the insistenceon flammable roof materials in thechaparral area of southern California, but similar..JlUitudes are exhibited throughout the world: Thedesign of subdivisions, also',' continues to defy principles of firesafety. Many areas include narrow,winding, or dead-end roads withinadequate water systems. Lots arefrequently too narrow to permiteffective vegetation removal. Without strong motivation to change,homeowners and developerswill continue to produce and maintain these dangerous communities.
• Most forest fire suppressionpersonnel are inadequately preparedfor fighting structural fires, whereasmunicipal fire departments are notalways fully trained or equipped forwildland fire suppression. Althoughrelatively new organizational systemsfor integrating a variety of fire protection resources and personnel haveproven effective, the special demands of fires in the wildland/urbaninterface often force firefightingpersonnel to perform unfamiliar tasks. The need to meld structural and vegetation fire expertiseon interface fires remains a formidable challenge.
The following actions and improvements are needed:

• Effective techniques and strategies to assess and manage fire hazards in the wildland/urban interface.
• Aids for planning, budgeting,and training for increased involvement in the residential/wildland interface to ensure a balanced capability in conducting structural andwildland fire suppression activities.
• Effective ways to educate property owners, land developers, insurance carriers, and local plannersabout vegetation fire problems andsolutions.
• Fundamental knowledge aboutthe physics of fire spotting andcrowning in the wildland/urban interface.
• Knowledge about relationshipsof building design, materials, and

landscaping with fire hazard and behavior.
• Improved understanding of whypeople build fire-prone homes inhighly some flammable areas andhow they respond to various motivational tactics to reduce vulnerability.
Who is responsible for the solution, the fire protection agency,the homeowner, the county planner?The responsibility for fire protection cannot be relegated to a singleelement of society. It calls for acombined effort. Just a few of thegroups that share in the responsibility include:
• Homeowners• Fire protection agencies• Local and regional planners
• Media and communication experts
• Insurance carriers• Builders, contractors, and archi

the problem would greatly reduceits impact. We all must take a handin solving the problem. We muststrive to avoid a 20th-century Peshtigo fire. There is no justificationfor continuation of such a serioushazard to life and property.•

Chilean Fire CourseKen Dittmer
Director, National Advanced Resource TechnologyCenter. Marana, AZ
Smokey Bear and his Chi/ean counterpart, Forestin the beaver, share the fire prevention messagewith Chilean schoolchildren.
For the third time in as manyyears, firefighters from Central andSouth America, Spain, and Portugalgathered for training in various aspects of fire suppression, The mostrecent session, in late Novemberand early December, 1985, was heldnear Santiago, Chile, rather thanat the National Advanced ResourceTechnology Center (NARTC), Marana, AZ, where the two previouscourses had been held. Through thecombined efforts of 17 fire expertsfrom Spain, Argentina, Chile, andthe United States, 56 firemen representing 15 countries were trainedin the latest techniques and philosophies of fire suppression. It is hopedthat these individuals will he ableto train others upon returning home.
During the 2 weeks of classroomtraining, the students were givencourses in effective training techniques, fire behavior, preventionand detection, fuels management,organization for suppression,line construction, and air operations.A week of field exercises in earlyDecember, the start of the fire season south of the equator, affordedthe students an opportunity to applywhat had been presented in theclassroom and to participate in a

prescribed burn. Field trips to national and private fire facilities andforest operations exposed thetrainees to a fine example of organization and cooperation in an environment similar to what they areaccustomed to at home.
Funding for Tercer Curso International Avanzado, El Combate deIncendios Forestales was made available through the Agency for International Development (AID); Corop-racion Nacional Forestales(CONAF), the national land managing agency of Chile; and the U.S.
Department of Agriculture ForestService.
Smokey Bear made his first tripoutside the United States, joininghis Chilean counterpart, Forestin, abeaver, in promoting fire prevention.Smokey and Forestin visited severalschools to pass out fire preventionmaterial and appeared on nationaltelevision.

Florida NIIMS Resource InventoryProgramJ.P. Greene and James Brenner
Fire management specialist and fire prevention coordinator, respectively, Florida Division of Forestry,Tallahassee, FL
When the Florida National Interagency Incident Management System(NIIMS) Task Force was formedin 1982, one of its first actions wasto form a logistics working teamwith the mission of developing aworkable wildland fire suppressionand support resources inventoryfor the State.
In order to inventory resources,it is first necessary to define theresources in such a manner as toensure that the inventory is uniforrnand accurate. When consideringfire suppression resources, however,enough flexibility must be built intothe system to allow for variationsin equipment while ensuring that theresource will do the job desired.Using the southern California definitions as a model, the team generateda list of resources adapted to theSoutheast in general and Florida inparticular. As outlined in nationaldoctrine, resources are typed by capability, with lower numbers havinggenerally greater capabilities.
After adoption of the resourcedefinitions, an inventory method wasdevised. An inventory form wasdeveloped and distributed to the 17Florida Division of Forestry districtsfor completion. Fire departments,forest industry cooperators, andFederal, State, and local agencieswere surveyed by county unit. The
1986 Volume 47, Number 3
resulting individual forms were thenentered into a computer program.
The NIIMS resource computerprogram requires an IBM PC orcompatible unit with 256 K memory. The software used is RBASE4000 or 5000, published by Microrim, Inc., and the NIIMS programdeveloped by the Florida Division ofForestry. The data-base size is limited only by the number of bytes perdisk. The Florida data is currentlystored on two double-density, twosided floppy disks with approximately 364 K on each.
The two disks contain 1,268 address records, 1,813 radio recordsand 3,197 equipment records. Thisdoes not mean that there are 3,197pieces of equipment recorded onthose two disks; rather, it means thatthere are 3,197 lines or recordsavailable. The actual numbers ofequipment recorded are 3,055of type I, 2,529 of type 2, 1,620of type 3, and 1,099 of type 4,for a grand total of 8,303 piecesof equipment on record.
The data-base is divided into threerelations-addresses and relateddata, radios and related data, andequipment types and amounts. Forthose using RBASE 5000, it maybe desirable to rewrite the reports sothat all three relations can be accessed at the same time.
To use the data, RBASE is loadedinto the PC, the appropriate data
disk is selected for the area involved, the data base is called up,and the program is run followingthe menu and instructions presentedon the computer monitor. Editingof the data follows much the sameprocess.
Through the menu, the programwill:
I. Display contact data (address,telephone number, etc.) for agenciesby cooperator, county, district, orstatewide.
2. Display equipment data.3. Display radio equipment.4. Display all equipment and radio
data for a selected cooperator,county, or district.
5. Search for specific kinds ofequipment by county, district, orstatewide.
6. Search for specific radio frequencies by county, district, orstatewide.
Through the use of RBASE Extended Report Writer software, thedata may be manipulated in variousways to produce mailing lists andother products.

Use of Dispenser
Successful operations were conducted in February 1986 on theAppalachicola National Forest inFlorida and the Kisatchie NationalForest in Louisiana for fuels reduction burning. The England Air ForceBase uses a portion of the Kisatchie National Forest as a firingrange for A-10 aircraft. The Forestmaintains the fuels on the area to
second. At aircraft speed of 50miles per hour. ignitions can beplaced from 25 to 200 feet apart,as desired. Spacing can be varied bychanging dispenser speed and/oraircraft speed.
The machine, a Premo-Mark IIIdispenser, is manufactured by PremoPlastics Engineering, Ltd., of Victoria, BC, Canada, and has provento be a very effective aerial ignitionsystem for both prescribed fire andburnout/backfire operations on wildfires.
About the size of Ping-Pong balls(33 mrn), the plastic spheres contain3 grams of potassium permanganate(KM"04)' When the spheres areinjected with I milliliter of ethylene

How the Dispenser Works
The dispenser is portable (about100 pounds) and can be mountedin a helicopter or fixed-wingaircraft. The dispenser performs thefunction of systematically injectingthe spheres with ethylene glycol
During the early 1960's, Australian foresters developed an aerialignition system to ignite spot firesin large blocks of eucalyptus to consume litter and reduce a fire hazard(1). The system has been used inthe United States since the early1970's by private industry and someState divisions of forestry but wasnot approved for use by the ForestService until 1986.
After safety testing by the Missoula Equipment Development Center (ED&T 4E42 P14, May 1985),the Southern Region (R-8) wasasked to develop a user's guide onoperating procedures prior to approval of the system by the ForestService.
The operating guide was completed in February 1986, followinga workshop held in Tallahassee,FL, and attended by representativesfrom each Forest Service Regionand the Washington Office. ForestService regulations require eachoperator to attend an 8-hour workshop to obtain certification to operate the dispenser.

The 3:500acres were burned in 1 hour usingthe plastic sphere dispenser anda Bell 206-B helicopter. Asthe smoke cleared, the A-lO's wereflying again. Under these conditions,
1986 Volume 47, Number 3
it is imperative to' complete theburning operation on time (the AirForce does use real bullets!). Inanother operation, 11,285 acres wereburned in 9.4 hours of flight timeover a 3-day period.
Cost of ignition is about $1 peracre. Plastic spheres are about13 cents each, and antifreeze is inexpensive. One ignition spot peracre gives satisfactory results in the
piney woods of the South. Thedispenser holds I gallon of antifreeze, which will inject 7,000spheres. Thus, the dispenser hasthe capability of burning 7,000 acreswithout the helicopter returning tothe helibase. If the bum boss is onboard the helicopter, several areascan be burned during a single flight.
Linear spacing of ignition withthe wind causes excessive heat asflank fires merge. A grid patternwith shorter flanks seems to produceless intensity (2).
Holding crews are needed oneach bum unit but may progressto another unit because ofshort bum out time.
Efficiency and simplicity of theplastic <sphere dispenser make ita desirable alternative ignition sourcefor prescribed fire and wildfireburnout.

Fine Tuning the Incident CommandSystem
James R. Abbott
ICS working team chairman, forest supervisor, LincolnNational Forest, Alamogordo, NM
The Incident Command System(ICS) received an effective test on aninteragency basis during the 1985 fireseason. Although some units had littletime to train and prepare, their firstuse of the system on actual fires wentquite smoothly. This learning experience provided a practical means ofbridging gaps between fire management systems and promoting an understanding of the differences in terminology and organization. It alsoprovided an opportunity for experienced and knowledgeable people tocritique the system and begin to suggest improvements that should bemade. In addition, adaptations to local needs were considered.
As all agencies gain experience inusing ICS there will be a natural tendency to propose modifications to meetspecific local concerns. ICS is intended to be flexible enough to meetlocal needs; however, uncoordinated,independent changes could affect thesystem's utility as an interagencytool. It is also probably true that somechanges are suggested only becausenew users do not fully understand
10
how a particular problem is meant tobe handled.
Other organizations such as law enforcement agencies and various emergency services are also adopting thesystem for their use. Although thisexpansion has many positive aspectsit could produce more variations inapplication that mayor may not beapplicable to wildland fire. Thus,wildland fire agencies must carefullymanage system changes if the intended interagency management benefits are to be realized.
The National Wildfire CoordinatingGroup (NWCG), through the ICSworking team, provides the mechanism to coordinate the maintenanceand revision of ICS with appropriateinput and assistance from involvedand interested agencies. Proposalssuggested through team members, ifaccepted by the NWCG, will be incorporated into the system on a periodic scheduled basis. Without this cooperation, different agencyapproaches could soon create problems in applying the system in interagency situations.
Controlling system change throughthe NWCG has a high payoff for theagencies and States involved. Each
. idea and need can be examined byusers in a way that features which enhance the system can in tum beadopted. Fine tuning in this way mayrequire more time but the alternativeof each agency modifying the systemon a continual basis would seriouslydetract from the usefulness of thesystem.
The ICS working team has a setprocess for considering all suggestions. The process used for considering all suggestions is shown in figure1.
What can you do if you have a suggestion for improving the IncidentCommand System?• Analyze and document the benefits,
costs, and consequences of theproposal.
• Review the proposal with agenciesthat you work with locally to obtaintheir ideas.
• Submit the proposal through agencychannels or to the author or an ICSworking team member. •

As it is becoming more widelyused across the Nation, the IncidentCommand System (ICS) has leftsome of us in the wildland fire protection agencies with questions abouthow fire incidents are intended tobe broken down into manageable geographic areas.
Divisions. as they are describedin ICS, are intended to representa geographical area for the purposeof organizing and directing fire suppression resources on wildland fireincidents. Some of the concerns thathave been expressed about the useof ICS divisions include a belief thatthe division may encompass toolarge a geographical area and thatsome additional smaller geographicalarea designator may be needed.There has also been a reluctanceto use ICS divisions on initial attackoperations or on small multioperational period fires because of thelack of readily available qualified division supervisors.
Some of these concerns can beaddressed by accepting the ideathat using the ICS term "division"to refer to geographical areas onyour fire incident does not necessarily indicate that the division coversa large area or has a large num-ber of resources or even that a person qualified as a division supervisoris commanding that division. The
12
Initial Attack Incident Commanderwho separates an incident into twoor more .divisions, regardless ofthe size of the incident, has madean important step towards implementing ICS. If the incident escalates in size and complexity theincident commander is in a positionto expand the organization accordingly.
Even on a relatively small incident, the Initial Attack IncidentCommander, with one crew, cantake one side of the fire and call itdivision A, assigning a second crewto take the other side of the fire,division B. There is no real need toassign someone qualified as a division supervisor to command a division until or unless the personneland resources required by that division become extensive enough tomake such an assignment necessary.
Another concern in our adjustmentto the use of divisions in ICS isthe loss of the lesser geographicalarea designator, the sector, thatmany of us were accustomed to inour previously used incidentmanagement system, the Large FireOrganization (LFO). Perhaps itwould be helpful to consider thatin the old LFO, even when a sectorwas used within a division, oftentimes further informal unstructuredgeographical separations were-
employed within the sector. For example, the sector boss would haveone crew boss cover from pointA to point B and another crew bosscover from point B to point C andso on.
lt is also perfectly acceptablewithin ICS to use divisions that incorporate other lesser geographicalareas as designated by the divisionsupervisor. For example, the division supervisor on a major incidentmay decide that he needs help insupervising fire control lineconstruction in part of the division.He delegates that task to a personqualified as task force leader fromamong the division's assigned singleresource bosses.
lt is important to realize that ICSshould not be seen as limitingwhat we do in dividing or organizing our fires. Instead, ICS shouldbe seen as a basic framework for organization that can be applied toinitial attack and, if necessary, systematically expanded to handle extended attack or even major incidents.
Sharing experiences, problems,and solutions among all the users ofICS still offers the promise thatall of us with a fire protection mission can improve our own operational abilities as well as our abilityto work mare effectively together.

les Qualifications
Marvin Newell, Bernie Erickson,and Jim Schneider
Staff assistant and computer systems programmer, respectively, USDA Forest Service; and forester, USDI Bureauof Indian Affairs; Boise Interagency Fire Center, Boise,ID
In 1984 the National WildfireCoordinating Group's (NWCG) qualification and certification workingteam, now the Incident CommandSystem (ICS) working team, published the Wildland Fire QualificationGuide (I). This guide includes theNWCG requirements for minimumtraining, experience, and physical fitness for positions in the ICS. The result of these common standards hasbeen the formation of a nationwidepool of wildland firefighting personnel who are qualified to perform firesuppression jobs fur which they havebeen certified. Some agencies'havesupplemented the guide with agencyrequirements for their own use.
After the production of the qualification guide, an obvious next stepwas to assist managers by developinga data management system to recordand track information necessary forqualifications. The ICS working teamdescribed the needed criteria, and theForest Service agreed to develop, test,and recommend such a system to theNWCG. The result was an automatedrecordkeeping system for wildlandfire qualifications that has been accepted by NWCG (fig. I). The program resides at the Ft. Collins Computer Center (FCCC).
Basically the program is a datamanagement system for personnel involved in wildland firefighting. Qualifications are determined by agencymanagers rather than by computeranalysis. The initial transition to ICSis accomplished by entering the position(s) that the individual has been
1986 Volume 47, Number 3
qualified to perform in, based upon alocal management review of his or hertraining and experience. Target positions for future qualification can beentered as well as subsequent trainingand experience. Planned training, special skills, or other information can beentered in the remarks section. Theprogram has the capability to createshort history files suitable fordownloading to microcomputers foruse in locally developed applications.
The information is transferred fromthe data entry form (form 320) to acomputer data file format by whatever
data entry system is. available to theuser. Forest Service users can useForms Entry Systems (FES) on DataGeneral equipment. Other userswould have to find a means on theirlocal system that could communicatethe resulting data file to FCCC forprocessing by the program or use dataentry facilities available at FCCC.
Agencies or units interested in thesystem should order the needed materials from the Boise Interagency FireCenter warehouse. There are fouritems available: User's Guide for theADP System, catalog #1516; PMS
13
Form 320 for manually recording andstoring data, # 15J7; red cards withthe headings preprinted for typewriteror manual use, #1518; and blank redcards for computer printer use,# 1519. The Wildland Fire Qualifications Guide, PMS 310- J, which isnecessary for determining nationallevel qualifications, is #1414.
General Services AdministrationSupports Firefighters
The General Services Administration (GSA) has been a member ofthe wildlife suppression communitysince 1956. Through its FederalSupply Service (FSS), GSA contracts for wildfire suppression equipment and supplies needed to helpprotect the Nation's forest and grassland resources from the ravagesof fire. FSS considers its wildfiresuppression equipment program second only to national security inorder of priority.
An FSS catalog, "Wildfire Suppression Equipment and Supplies,"is the basic supply publication foruse by the United States ForestService, Bureau of Land Management, Bureau of Indian Affairs,National Park Service, and otherForest Service certified participantsin the Governmentwide program.Because GSA complies with all regulations governing the competitivepurchasing of items, customer agen-des may, in compliance witI-! theirinternal agency procedures, order directly from GSA.

gories (general cause, specific cause,and class-of-people) were addedto pinpoint both the cause and whostarted the fire.
Although to our credit we'vemaintained consistency in our firecause reporting system, unfortunatelywe've also created categories thatare repetitious and not mutually exclusive. As a result, we can easilyhave multiple classification schemesfor a given fire cause, making itdifftcult to determine from fire-report data the actual cause and personresponsible for a particular wildfire.For example, a dump fire set by oneor more persons is reported in theNortheastern United States usingseven different cause and class-ofpeople combinations (table I). Whatseems simple to record tums outto be complex!
Compounding the problem ofoverlapping or non-mutually exclusive categories is the broad andrepetitious nature of our fire-causereporting system.
Our system also lacks any wayfor reporters to indicate the certainty
Because of certain social trendsoccurring in the United States andalso because of some relatively newadministrative requirements, ourneeds for fire prevention informationare changing. I will describe ourcurrent system of information gathering, pointing out some of thestrengths and weaknesses of the system, and then discuss the new demands for fire prevention information growing out of social changeand administrative mandates in theUnited States.
Most of our current fire prevention information, like yours, comesfrom our individual fire reports.The key elements from a preventionstandpoint are: statistical cause,general cause, specific cause, andclass of people. Statisticalcauses, which are used by all protection agencies in the United States,are reported annually in our "Wildfire Statistics." General cause isdefined as the general type of landuse activity responsible for a fire,and specific cause as the specific activity or ignition source causingthe fire. This cause classificationsystem, though amended occasionally, has been used by the ForestService for 80 years and appears onState and Federal fire reports invarying formats. When combinedwith location, size class, andacreage burned information, it notonly gives us an idea of whatour problems are but where and howbig they are. Based on this information, our land managers select ap-

propriate fire prevention programsand allocate resources to solve theirwildfire problems. By monitoringtrends in fire causes, they also usethe information to evaluate the impacts of their programs.
Although managers find this process workable, it still can be improved. No matter how much statistical wizardry we scientistsperform on the data, we can't makeit any better. Although we take whatis on the forms and transform itinto impressive graphs and chartsfor our user groups, what comes inmust go out. Therefore, if thedata coming in are inaccurate whatgoes out is inaccurate. One of thereasons for inaccurate data is the design of the reporting system; theother part is due to our assessmentof fire causes at the fire scene.
First, let's look at the reportingsystem itself. Ours follows aprogression of "add on" information. Eighty years ago, westarted with eight basiccauses. These apparently were inadequate for over the years new cate-

of their fire-cause data. That is,once entered on a fire report form,reliable causes are indistinguishablefrom unreliable ones. With no "unknown" category available, an unknown cause is typicallyclassified as a smoking. incendiary,or miscellaneous wildfire. Becausereporters cannot indicate the reliability of fire causes, the accuracyof fire-cause data is often questionable, leading to erroneous assumptions about the fire preventionproblems.
Even if our reporting system wereperfect, we would still have thedifficulty of assessing the cause ofa wildfire at the fire scene. Whatit boils down to is that weoften don't do a good job of firecause investigation. And, if We
don't do a good job investigating,what goes on the fire reports andinto our data files isn't very goodeither.
So 'what are we doing about allof this? It wasn't too long ago thatthe building block system was proposed to replace our traditionalsystem. This new system includedthe:
• Form of heat energy that ignited the fire: for example, flames,sparks, and hot surfaces from a vatiety of sources.
• Reporter's certainty of heatof ignition.
• Equipment involved in startingthe fire: e.g., cooking equipment,electrical equipment, woodlandequipment.
16
- -----
• Material first ignited: grass,leaves, paper, hay, etc.
• Ignition factor: how the formof heat energy and the material firstignited combined to start a wildfire-s-for example, incendiarism, misuse of equipment, mechanical failure, or design deficiency.
This system also included thetype of person responsible for flres,the person's age and sex, and theprimary activity the person was involved in when the flre started.Although the idea was good,it wasn't widely accepted becauseit was too cumbersome to use (25pages of categories to choose froml)and broke too much with tradition.
The Forest Service decided tocompromise. Our new fire reportcontains only statistical causes; debris burning, campfires, incendiary,railroads, smoking, equipmentuse, children, miscellaneous, andlightning. We're back to where westarted in 1905! These arereported uniformly across the Nation. The system is obviously simpleto use and historically compatiblewith previous fire report data.If, however, managers want moredetailed fire prevention informationfor their administrative units, theycan also use the building block system contained on a supplementalfire report form.
Finally, to improve the qualityof the data, fire-cause investigarionis being emphasized nationwide.This is, in part, a reaction to the in-
crease in arson in the UnitedStates. Nationally, it's the numberone cause of wildfires. To get abetter handle on the magnitude ofthis problem, the wildland fire COmmunity has decided to improve itsinvestigative skills. With better investigative work comes better wildfire cause data.
What I've just described is ourcurrent system of reporting datathat is useful to the fire preventioncommunity. And it's a traditionalsystem. We use the information, aswe have for decades, to defineour fire prevention problemsin terms of number of fires, theircauses, acreage burned, and soforth. And, if we're asked to demonstrate our achievements. we pointto the increase or decrease in human-caused fires over time. But inour day and age, this is nolonger adequate.
With tightening budgets, cutbacksin our management programs andpersonnel, and mandates from Congress to demonstrate the cost effectiveness of our fire managementactivities, the Forest Service hasimplemented a national system foranalyzing, from an economic standpoint, fire management programs.
The system provides a formalprocess for evaluating the efficiencyand effectiveness of fire programsat the national and regional levels.
When I say "fire programs,"1 mean total fire management programs which include wildfireprevention. In the past, we've

tended to separate prevention fromthe rest of the fire picture. It wasalways an isolated event outside ofthe mainstream. Now. we're lookingat the complete picture, includingprevention, presuppression, and suppression activities. This brings upa number of questions about theeconomics of fire prevention programs. For instance:
• How much do our fire prevention programs cost us and whatdo they "buy" us in terms of number of wildfires?
• What is an efficient programlevel?
• What is an efficient budgetlevel?
• How many fires do these efficient program and budget levelsgenerate and what's the cost plusnet value change of these fires?
• How does fife prevention interact with the rest of fire management? If we reduce the number offires, how does that affect our suppression forces?
These are some of the questionsthat those of us in fire preventionare now asking and are required toask. We're no longer looking atjust an increase or decrease in thenumber of fires but, in addition,the costs and effects of thesechanges.
So, what kinds of additional prevention information do we need?
Initially we need to document:1. The kinds of educational, engi
neering. and law enforcement activities we perform.

of Arkansas. This figure depictsonly one aspect of their fire prevention program-law enforcement activities targeted at arson wildfires.
The axis pointing downward reflects the quantity or amount oflaw enforcement activity (in thiscase the number of prosecutions,convictions, and settlements) inArkansas; the axis pointing to theleft depicts the cost of these enforcement activities. The axis pointing to the right indicates the numberof arson wildfires that can occurin Arkansas, the axis pointing upward shows the suppressioncosts (C) plus net value changes(NYC) due to these fires.
The lines of this graph representrelationships. The diagonal line inthe lower left quadrant, for example,represents the relations betweenlaw enforcement activities and thecosts of those activities. This lineshows that as law enforcement activities increase, the costs of thoseactivities will also increase.We're assuming for the purposesof this exercise that each unit ofenforcement, i.e., each prosecution,conviction, or settlement, costs Arkansas $500. The curved line in thelower right quadrant indicates thatat low levels of law enforcementeffort, Arkansas can expect a highnumber of arson fires, but as theState increases its enforcement efforts, it can expect a gradual decrease in these fires. Finally, thestraight line in the upper right quadrant indicates that as the number
18
of arson fires increases, the C +NYC will increase correspondingly.The curved line in this quadrantreflects Arkansas' total fire management costs, including not only theC + NYC caused by arson wildfiresbut also the State's prevention (lawenforcement) costs.
So, how would a manager inArkansas use this diagram? Let'sassume that the manager is aimingto undertake 1,000 prosecutions,convictions, and settlements againstarsonists next year. That level oflaw enforcement effort (E), couldbe expected to cost about $500,000(C). (Follow the dashed line fromletter E to letter C.) Given those1,000 units of enforcement (E),1,300 arson wildfires (A) could beexpected. (Follow the dashed linefrom letter E to letter A.) The totalfire management costs (T), includingprevention (law enforcement) costs,would be about $8.7 million-themost efficient level of operation (thelowest point of the curve). (Followthe dashed line from letter A to letter T and over to the C + NYCaxis.)
What if the manager's preventionbudget were cut in half, from$500,000 to $250,000? What effectswould that have? With a $250,000prevention budget (Enforcement Costaxis), the manager could affordabout 500 units of enforcement (i.e.,500 prosecutions, convictions, andsettlements). With this reduced levelof prevention activity, about 1,400arson wildfires could be expected.
The C + NYC due to these additional fires would be $8.5 million,and the total fire management costwould add up to $8.8 million (C +NYC + enforcement costs).
There's a lot more that we cando with this diagram from an analysis standpoint, but I believe youcan get an idea of where we areheaded with our analyses of fire prevention programs. Although thisis a simplistic model, we're hopingto improve it greatly by collectingcost and prevention activity data foreach component of fire preventionso that we can more adequately reflect what's happening in the realworld. If we can do that, then wecan turn this into an operationallyuseful system.
Of course, no matter how sophisticated we get, we can't do ourjob well unless we have good fireprevention information. Some ofthat valuable information will comefrom better reporting systems andsome from better fire cause investigation. And with improved qualityof information, we scientists willbe able to give our clients betterproducts to work with. •

The True Story of thePulaski Fire ToolJames B. Davis
Research forester, USDA Forest Service, Forest Fire andAtmospheric Sciences Research, Washington. DC
The nickel-plated pulaski looks asgood as new in its glass-fronted Collins Tool Company display case at theSmithsonian Museum of Arts and Industry in Washington, DC. Surrounded by equally shiny cutting toolsof all description, the pulaski was firstput on display at the Nation's Centennial Exhibit in Philadelphia in 1876.
Conventional wisdom holds that thepulaski fire tool was invented byEdward C. "Big Ed" Pulaski in thesecond decade of the 20th century. EdPulaski, a descendant of AmericanRevolution hero Casimir Pulaski, wasa hero of the Great Idaho Fire of1910, leading his crew to safety whenthey became imperiled. He was alsoone of a group of ranger tinkererswho struggled to solve the equipmentproblems of the budding forestry profession. However, the pulaski tool ondisplay at the Smithsonian must havebeen made when Big Ed was no morethan 6 years old!
In the early days of forestry in thiscountry, fire tools were whatever happened to be available. The earliestmethods of firefighting were confinedmostly to "knocking down" or "beating out" the flames, and the toolsused in the job were simple and primitive. The beating out, when such anapproach was possible, was often accomplished with a coat, slicker, wetsack, or even a saddle blanket. Acommonly used tool was a pine boughcut on arrival at the fire edge (4).
Soon farming and logging tools,available at general and hardwarestores, came into use. These included
1986 Volume 47, Number 3
the shovel, ax, hoe, and rake-all basic hand tools developed over centuries of manual labor. Even afterfirefighting became an importantfunction of forestry agencies, thesetools were accepted as they were,wherever they could be picked up,and little thought was given to size,weight, and balance. There appears tobe no record of the use of the CollinsTool Company pulaski for fire control. Most likely, it was sold to farmers for land clearing and may havebeen forgotten by the late 1800's (2).
With the advent of the USDA Forest Service and State forestry organizations, a generation of "ranger inventors" and tinkerers began toemerge. It became apparent that careful selection and modification was essential for efficient work and laborconservation. In the early days whenalmost everybody and everything hadto travel by horseback transportationwas a particular problem. For yearsforesters worked on the idea of combination tools. Most of the attemptswere built in home workshops, andmost "went with the wind." Two important survivors, now in general use,are the Mcleod tool, a sturdy combination of rake and hoe, and the combination of ax and mattock. TheMcLeod was probably the first firetool to be developed. It was designedin 1905 by Ranger Malcolm McLeodof the Sierra National Forest.
Who first invented the ax-hoe combination and used it for firefighting isa matter of minor dispute. Earle P.
Dudly claims to have had a pulaskilike tool made by having a lightweight mining pick modified by a local blacksmith. He says he used thetool for firefighting in the USDA Forest Service's Northern Rocky Mountain Region in 1907. Dudly was wellacquainted with Ed Pulaski, and thetwo had discussed fire tools.
Another account of the origin of thepulaski is that William G. Weigle, supervisor of the Coeur d' Alene National Forest, thought of the idea-butnot for firefighting (5). Rangers EdPulaski and Joe Halm worked underhim <all three became heroes of theGreat Idaho Fire) at Wallace, ro, thenheadquarters for the Coeur d'AleneNational Forest. At that time, planswere being made for some experimental reforestation, including the planting, pine seedlings. As SupervisorWeigle planned the job, he decided anew tool was needed to help with theplanting as well as other forestrywork. He decided on a combinationof ax, mattock, and shovel. One dayin late 1910 or 1911, Weigle sentRangers Joe Halm and Ed Holcomb toPulaski's home blacksmith shop totum out a combination tool that mightreplace the mattock that was then incommon use for tree planting. Halm,with Holcomb helping, cut one bladeoff a double-bitted ax, then welded amattock hoe on at right angles to theformer blade position. He then drilleda hole in an old shovel and attached itto the ax-mattock piece by means of awing bolt, placing it so the user couldsink the shovel into the earth by ap-

plying foot pressure to the mattockblade.
The rather awkward device was nota success as a planting tool. Probablythe whole idea would have been abandoned had not Ranger Pulaski beenfascinated with the possibilities of thetool. He kept using it, experimentingwith it, and improving it. He soondiscovered that the bolted-on shovelwas awkward and unsatisfactory. Heabandoned the shovel part and alsolengthened and reshaped the ax andmattock blades. It is too bad Pulaskidid not know about the Collins Toolpulaski-it would have saved him alot of time. Nevertheless, by 1913Pulaski had succeeded in making awell-balanced tool with a sharp ax onone side and a mattock or grubbingblade on the other.
Pulaski use now spread throughoutthe Rocky Mountain region. However, it was used not for tree plantingbut for fire control. By 1920 the demand was so great that a commercialtool company was asked to handleproduction.
Although the pulaski went intowidespread use in the Rockies in the1920's, it saw little or no use in otherareas. Prior to 1931 the USDA ForestService had no good internal methodfor handling equipment developmentand promotion. Most new equipmentideas were introduced and discussedat the regular Western Forestry andConservation Association meetings(3, 7).
By the mid i930' s, with the adventof the CCC, fire tools began to prolif-
20
erate, and the USDA Forest Servicesought to standardize tools rather thandevelop new ones. It was at an equipment standardization conference atSpokane in 1936 that the pulaski toolwas proposed for national distribution. The conference instructed theUSDA Forest Service's Region I todevelop and further test a prototypesuitable for servicewide use (6, 8).

Although Ed Pulaski may not haveinvented the first fire tool put intogeneral use or even first thought ofthe tool that bears his name, he diddevelop, improve, and popularize thepulaski. The General Services Administration now puts out bids for morethan 35,000 new pulaskis each

Of the 361 records examined,201 or 55 percent indicated that thefires were set within 6 miles ofthe responding fire station. Almost19 percent of the arsonists set fireswithin I mile of the station (fig. I).Since most of our ranger stationsare located in rural communities thisinformation may indicate that thefire setters live in or near town.
The majority of the arson fires(5I.7 percent) were discovered bylocal residents. This fmding is consistent with the percentage of allfires discovered by the local citi-

Forest fire arson is a problemof some concern for forest fire control people in Wisconsin. In thepast 4 years, 567 forest fires wereintentionally set.

Fire responsibility for the remainder of the State lies with eitherthe township or municipal government.
Forest fire arson, for purposesof this article, consists of fires willfully set by anyone to burn vegetation or property not owned orcontrolled by the fire setter andwithout the consent of the owneror owner's agent (I).

In muchof the DNR's jurisdiction, the burning of trash on Sundays is prohibited, following the premise thatcareless campers, hikers, sightseers,and other recreationists would keepthe frrefighting forces busy. It appears that, with the demonstratedpeak of arson activity on Sundays,the banning of trash burning maybe even more justified.
The pattern for time of day forfire starts is interesting. Fire settingactivity seems to begin at about1200 hours, peaks at 1500 hours,decreases to a low point at 1700hours, and then rises again to alesser peak at 1900 hours. Fire setting then decreases to a low pointat 2200 hours, at which time over

quent fire runs by the fire agencies,ease of ignition of forest fuels atthis time of year, and the balminessof the weather, combine to stimulatefire selling behavior.
The day of the week that themost fires occurred was somewhatsurprising. Sunday ranked highest,with an average of 21 percent occurring on that day; 35 percent occurred on Saturday or Sunday.Forty- eight percent of all the firesoccurred on the first 3 days of theweek-Monday (14.8), Tuesday(18.4), and Wednesday (14.8).Thursday and Friday ranked thelowest at 9.7 and 7.5 percent, respectively (fig. 3).
Arson fires seem to pick up on
zenry as opposed to lookout towers,aircraft, or other means.
Almost 60 percent of the incendiary fires occurred in April, and bythe end of May, more than 75 percent of the State's incendiary fireshad been set (fig. 2). There appearto be two rather significant peaks.One is an II-day period from April24 through May 4 when 27 percentof this type arson fires were set.Another peak occurred during a9-day period from April 9 to April17, when 19 percent of the fireswere set.

fire setting pattern is contrary to thegeneral belief the public has thatarson is a crime of the night. Ourexperience shows that wildland arsonoccurs in broad daylight during themost dangerous burning time, whenour firefighting forces are busiestwith accidental fires and when theset fires could potentially do themost destruction.
Another myth was brought downwith this study. It had generallybeen felt that State-ownedlands were targets for the arsonists.This proved not to be the case. Private landowners suffered the worstof the attacks-more than 57 percentof the arson fires occurred on private land. Federal lands weresingled out next with 15.3 percent,then State lands with 7.4 percent.The remaining fires were on county,municipal, and various highwayrights-of-way (fig. 5).
Of the 361 records that were studied, persons responsible for 54 fireswere identified, The demographicsdidn't produce any surprises: 97 percent were male and 63 percent were25 years of age and under. However, 24 percent were between 38and 56 years old. There seem tobe two main age groups involvedin fire setting: 25 and under andthe late 30's to early 50's (fig. 6and 7).
The people that set fires are generally not transients, vacationers,or summer people. Eighty percentwere identified as permanent residents, the group most likely to be

Properly equipped wildland firefighter in the process oj deploying fire shelter.
Introduction
Wildland fires trapped an estimated 200 firefighters during the1985 fire season. These entrapments,and the role fire shelters and otherpersonal protective equipment playedin saving lives and preventing serious bum injuries, have stimulatedgreat interest. The purpose of thisarticle is to provide field peoplewith additional information on thisvital safety equipment.
Fire shelters, special clothing,and other protective equipment existtoday hecause 28 years ago, afteran analysis of casualty-causing fires,the Forest Service committed itselfto developing effective personal protective gear for wildland firefighters.The Missoula Equipment Development Center (MEDC) has spearheaded this effort over the yearsand continues to improve the itemsthat make up the firefighter's personal protective system.
Personal Protective System
The basic components of the sys-tem include:
• Fire shelter• Hardhat• Goggles• Flame-resistant shirts and jeans• Leather boots and wool socksThe fire shelter provides protec-
tion during fire entrapment and protects vulnerable airways and lungs,which the other components ofthe system cannot do. We wroteabout the fire shelter in the last
26
issue of Fire Management Notes,so here we will focus on the other
items of personal protective equipment (PPE).

In
Together, these items protect firefighters from thermal and other jobhazards while they work. Severalkey requirements guide the MissoulaCenter's development and test workon PPE. Each item must protectthe wearer and not contribute to fatigue or injury by premature failure.In addition, it must be lightweight,functional, durable, comfortable, andeconomical. With regard to comfort,heat stress is a prime concern. Whenwe speak of economical equipment,we don't necessarily mean thelowest in price. We look at anitem's life-cycle cost, not just acquisition cost. A good example isflame-resistant clothing. A garmentthat costs twice as much as anothermay still be more economical ifit outwears the less expensive garment by a factor of more than twoto one.
Hardhat
With the possible exception ofthe fire shelter, the hardhat is themost important piece of wildlandfuefighting safety equipment. Hardhats have saved many lives andprevented serious injuries by protecting the wearer against falling trees,limbs, and rolling rocks.
The literature indicates that approximately 15 percent of the body'sheat is lost through the head, sohardhats, which are cooler andlighter in weight, are preferred overhelmets designed for structural firefighting. Special clips are addedto attach goggles and night firefight-
1986 Volume 47, Number 3
ing headlamps. As wildland firefighters confront more fires in areaswhere there are structures and associated electrical hazards, class Bplastic hardhats, which provide electrical hazard protection, are preferred.
Goggles
A study conducted from 1967through 1971 showed that eye injuries accounted for about 7 percentof all fire suppression injuries. Dust,smoke, brush and branches, andhot substances cause most eye injuries.
Thus goggles are an importantcomponent of the PPE system. Firefighters are dissatisfied with thegoggles now available. A recentsurvey indicated comfortable gogglesthat won't fog or scratch are oneof the firefighter's greatest needs.We hope to begin a project aimedat finding better fog-free gogglesfor forest workers that will meetfirefighting needs.
Development of Flame-ResistantClothing
Work on flame-resistant clothingbegan in 1958 concurrently withfire shelter development. The objective was to design garments thatwould offer firefighters protection(1) against flames, falling embers,and coals; (2) when dashing forsafety to avoid entrapment; (3) during entrapment without a fire shelterand added protection within a shel-
ter; and (4) if involved in an aircraftaccident.
Extensive use of flame-resistantshirts began in 1962 with the introduction of flame-retardant treated(FRT) cotton shirts. FRT cottontrousers were field evaluated alongwith shirts. But trousers are subjectto greater wear, and FRT cottonhad poor durability, so flame-resistant trousers were impractical untilNomex" fabrics became available inthe early 1970's.
After using orange FRT cottonshirts for several years, we switchedto yellow shirts in the late 1960's.Studies on PPE for urban firefighters showed yellow to bemore visible in dark and smokeyenvironments. Also, there were several incidents in which the orangeshirts were mistaken for flames andaircraft dropped fire retardant oncrews on the line.
Firefighters wore FRT cottonshirts for about 10 years. Then in1973, after many years of field evaluation, we adopted flame-resistantNomex" for shirts. Nomex" iswoven from a nylon-type fiber designed to withstand high temperatures. Like most fabrics, Nomex"bums if exposed to flame, but unlike the others, it stops burningwhen removed from the flame. Instead of melting or burning to ash,it forms a char that continues tohelp protect the skin. In 1974,Nomex'" pants became available.We've worked to improve thesegarments over the years.
27
Flame-Resistant Shirt
MEDC specialists worked withthe producer of Nomex" fiber andseveral fabric weavers for 3 yearsto develop a more comfortableflame-resistant shirt fabric. The newfabric has a more open, thickerweave. Weight and fire resistancyremain the same. Forest Servicefield evaluators said the new shirtsare cooler on hot days and warmeron cool nights. The openness ofthe weave improves evaporativecooling while its thickness traps airnext to the skin to keep the wearerwarmer at night.
The fabric feels softer, too, evaluators said. The softer fabric shouldreduce chafing problems some people experienced with the previousNomex" shirts.
To insure a better fit for morepeople, the shirts are being madein a new extra-small size.
Key features of the earlier designhave been retained. Sleeves are cutfull for ventilation plus free movement of tbe arms. This reduces fabric stress at the elbows and improvesdurability of the shirt. For addedprotection against radiant heat andfalling embers, the collar can beturned up. Sleeves can be drawnsnugly around the wrists with quickfastening Velcro" closures. Buttonsare oversized for easy fastening.Two large pockets with flaps holdmaps, note pads, and similar items.The shirt can be worn inside thetrousers, or outside of the jacket.Wearing the shirt inside offers the
28
most thermal protection.
Flame-Resistant JeansThe firefighters pants were re
designed into a basic jean cut. Forgreater comfort, they have a littlefuller cut in the crotch, upper leg,and seat. The new jean design features western scoop front pocketsand a return to hook and pile tabson the back pockets. These pocketsremain large for carrying extra personal items and to increase thermalprotection with a double layer offabric.
The zipper fly was retained, butthe waistband is now closed witha traditional metal jean rivet button.The button is embossed with theletters FSS for Federal Supply System.
These jeans also come in twonew waist sizes: 26 inch and 40inch. And there is a choice of twoinseam sizes, 3D and 34 inches.For those who need 31- or 32-inchinseams. it is easier to let out the3D-inch inseam than to cut and rehem the 34 inch. The 34-inch inseam can be let out to inseams of3S to 36 inches.
What To Wear with Nomex"
The other clothes worn withNome,," shirts and jeans affect theirprotective qualities. Underwear ofa polyester cotton blend is acceptable, but we recommend T-shirtsand undershorts of 100 percent cotton. AU-synthetic underwearshould never be worn. Two layers
of clothing, that is Nome,," plusunderwear, provide better thermalprotection. But don't wear otherwork clothing under or over yourNomexe garments, Doing so increases body heat and puts an addedload on the heart.
For colder weather and nights,jackets should be all wool, all cotton, or wool blends of at least 85percent wool.
Coveralls or Jumpsuits
Firefighters in some agencies wearNomex lltl or FRT cotton coverallsor jumpsuits, and we are often askedwhy the Forest Service doesn't usethem.
We favor shirts and pants anddiscourage coveralls and jumpsuitsfor these reasons: (I) Coveralls areusually worn over other garments.This restricts body cooling,which results in higher heart ratesand increased heat stress. (2) Coveralls are made from a single-weightfabric, but ideally different weightfabrics are needed for the upper andlower parts of the body; for example, a heavier, more durable fabricto protect legs from brush and general abrasion, and a lighter-weightfabric with a more open weave tohelp dissipate heat ftom arms, chest,and back. One-piece garments ofa heavy trouser-weight fabric, likework coveralls, restrict cooling.They also chafe parts of the upperbody if worn only over T-shirts.Jumpsuits are made from shirtweight fabric and do not provide

adequate leg protection. (3) Firefighter's clothing is produced ina limited number of sizes to keepcosts down. With such a limitedsize distribution, one-piece garmentsseldom fit many people properlybecause the distance between crotchand shoulders varies so much. Ina work situation this causes chafingand discomfort. (4) One-piece garments made from flame-resistantfabrics are expensive. Unlike shirtsand jeans, if part of the garmentbecomes unserviceable, the entiregarment must be replaced.
Flame-Resistant Gloves
Specially designed gloves areessential in protecting the firefighter's hands against blisters,scratches, small cuts, and minorbums during routine frrefighting.But they also play a major fire protection role in event of an aircraftaccident or fireline entrapment.
Reviews of past fire entrapmentsshow that those trapped burnedwhile attempting to flee entrapmentsometimes lost fingers if theywere not wearing gloves or if theirconventional oil-tanned work glovesburned or shrunk from intense heat.Additionally, reports from peopleentrapped in shelters emphasize theimportance of gloves in holdingdown hot shelter material withoutgetting burned.
After numerous material and design changes, MEDC's late-st modelforest workers' gloves appear tobe meeting firefighting and general
1986 Volume 47, Number 3
forestry requirements very well.The new gloves are full-grain,
chrome-tanned leather; previousmodels were split-grain leather. Fullgrain leather is stronger, so the newgloves wear better and last longer.Full-grain leather requires narrowerseam margins to hold stitches, whichreduces bulk. Compared with oiltanning, chrome tanning providesexcellent protection against heatand shrinkage. These gloves alsoresist stretching and retain theirshape better wet or dry because theleather is water and oil resistant.
A drawstring wrist closure keepsembers and debris from getting intothe gloves.
Leather Boots and Wool Socks
Past fire entrapment investigationsfound that good quality leather bootstraditionally worn for wildland firefighting provide adequate foot protection. All-wool or mostly woolsocks offer added thermal protection.Wool wicks moisture from the skin.This helps keep feet cooler anddryer, reducing the chance of blisters, a common firefighting injury.
The Forest Service requires thefirefighter to wear a lace-type leatherboot with at least an 8-inch top.Skid-resistant soles are required,with a lug-type sole preferred. Slipsand falls account for many firefighting injuries. One study overa lO-year period indicates that 17percent of injuries result from slipsand falls. So the importance of goodskid-resistant soles cannot be over-
emphasized.
Chain Saw Chaps
One last piece of PPE that we'dlike to review is chain saw chaps.Since not all firefighters wear them,we don't include chaps as a component of the basic PPE system.However, due to the extensive useof chain saws in firefighting, wefeel a brief review of this item isappropriate.
Chain saw chaps were redesignedin 1982. The redesign focused onincreasing sawyer protection andcomfort while minimizing costs.
MEDC tested many combinationsof materials to find the best protection with the least weight. Thenew outer shell is II-ounce Cordura" nylon, replacing the bulky 15ounce cotton canvas. Cordura'"cleans easily, resists tears and abrasions, and keeps the protective padfree of oil better than cotton canvas.The protective pads combine twolayers of woven Kevlar" with twolayers of Kevlar" felt. Kevlar" isan aramid fiber like Nomex", butwith more flame resistance. Moreover, because of its cut resistance, itcan slow and quickly jam the chainbefore cutters penetrate the leg. At 2pounds, the new chaps weigh 40percent less than the old style andoffer 50 percent more protection.
Quick-release buckles make thechaps easy to put on and take off.This is a nice feature for firefightingbecause the chaps can be easilyremoved to reduce heat stress when
29
sawing is completed. Leg strapshave been relocated to improve fitand minimize snagging, and a toolpouch was added to hold a roundfile, file guide, flat file, spark plugwrench, and screwdriver. A pamphlet titled "Inspecting and RepairingYour Chain Saw Chaps" is availablefrom the MEDC.
Respiratory Protection
Even though the personal protective system doesn't include any kindof breathing device, we want todiscuss briefly respiratory protection.
As we pointed out above, thefire shelter protects the firefighter'sairways and lungs during fire entrapment. But what about protectingthe working firefighter's respiratorysystem from smoke, dust, and hotgases?
Periodically, MEDC has beenfunded to search for effective, practical respiratory protection that
30
does this. Self-contained breathingapparatus used by municipal andindustrial firefighters are effectivebut impractical for wildland firefighting. The Center has testedvarious types of respirators, andall restrict breathing and don't filtergases well, exposing the wearerto high concentrations of poisonouscarbon monoxide and other toxicgases. For this reason, we haven'tbeen ahle to recommend respirators.
For limited smoke and dust protection, firefighters have worn bandannas for years and are beginningto use disposable dust filters.Bandannas or dust filters shouldbe kept dry. In intense heat, aswhen working against a hot flamefront, there is a possibility thatbreathing hot, moist air through awet dust filter or bandanna candamage the respiratory system.
Furthermore, firefighters shouldbe cautioned against covering too
much of the face. Cheeks and earsare excellent heat sensors. Coveringthem can lead a person to worktoo long in a hot situation. The result can be dehydration, heat stress,and prolonged elevated heart rateleading to premature fatigue, orworse.
Conclusion
Improvement of personal protective equipment is a dynamic process.Materials and production technologychange constantly. And newknowledge, particularly in the arenaof human physiology, is expandingrapidly. The staff at the MissoulaEquipment Development Centerkeeps up with these changes so asto continue to improve personalprotective equipment for the wildland firefighter. We always welcomecomments on product improvements.•

Using Interactive VideodiscTechnology in Wildland Fire BehaviorTrainingM.J. Jenkins and K.Y. Matsnmoto-Grah
Assistant professor and researchassistant, respectively, Departmentof Forest Resources, Utah StateUniversity, Logan, UT
,I' .
In recent years, fire research hasdeveloped a large body of complexinformation. Proper wildland firemanagement and use requires a thorough understanding of combustion,fire behavior, fire ecology andhistory, fire economics, fire effects,and prescribed fire practices. Largeareas of valuable resources andhuman lives are often at stake during prescribed fire and fire suppression activities, making thorough,up-to-date professional training essentiaL Because safety is such anoverriding concern, adequate trainingis mandatory to reduce risk.
Most fire management organizations require approximately 40 hoursof formal training as a basic prerequisite to any entry level suppressionposition. The curriculum includesfundamentals of fire behavior, firesuppression, fire organization, tooland equipment use, and safety. Firebehavior is central to this curriculum, and a subject taught by all firemanagement agencies. A complete,multilevel instructional packagedeveloped by the National WildfireCoordinating Group (NWCG) isthe training standard in fire behaviorfor all NWCG agencies.
Our project involves using existing fire behavior curricula in aninteractive Videodisc/computer training system. This disc will supplement existing training courses inwildland fire behavior and will include materials produced by NWCGon introductory, intermediate, and
1986 Volume 47, Number 3
advanced fire behavior. In addition,elements from existing courses onfuels inventories, debris prediction,and prescribed fire will be includedon the program (9).
The objective of this project isto demonstrate the application ofinteractive videodisc instruction towildland fire management byproducing a program on wildlandfire behavior. This training packagewill not replace existing instructionalmaterials, but will act as a supplement to current training materials.The project is funded by NWCGand is being administered by Bureauof Land Management, Division ofTraining, Boise Interagency FireCenter.
Interactive Training andInstruction
Basic principles of interactivedesign must be clearly understoodin order to realize the benefits whichcan occur through the use of aninteractive training medium. In orderto provide useful interaction betweenthe learner and the instructionalprogram, intellectual options shouldbe provided that allow users to actively make decisions and be subjected to their consequences (1). Forexample, an incorrect calculationof a fire's rate of spread in a givensimulation may result in inappropriate tactical response to the incident. Learners make choices, andthe system responds, sometimes in
surprising ways. An interactive videodisc lesson should allow learnersto "create" their own training experience, to interview and make frequem decisions about the content ofthe lesson and the way it isdelivered.
The instructional system respondsinstantly to learner input by providing relevant, previously designedinstructional cues, reinforcement,and feedback segments composedof computer text and graphics, stilland motion video, with or withoutaudio. The scope, sequence, rate,style, duration, level, and mediumof instruction is, to a large degree,determined by a dialog betweenthe learner and the system.
The linear, presequenced formatof most traditional instructional materials such as texts, workbooks,films, or slide/tape presentationstreats all learners alike and does notallow the learner to actively takepart in the choice of sequence orcontent of a lesson (5).
Interactive video is a powerfulmedium, bringing together the emotional impact of video and film andthe interactive capabilities of thecomputer. Development of interactive videodisc instruction has, toa large degree, mirrored computerassisted instruction (CAl). Like CAl,interactive videodisc instruction canbe used as a tutorial, for drill andpractice and in simulations, as wellas for information storage.

A branching program has alternate tracks for therapid and slow learner, can followup certain responses in detail, allowlearners to see only the materialsthey need or want to see, test learners on the comprehension of thematerials, allow learners to repeatmaterial or to have remedial workwhen needed, and effectively pose aquestion without demanding oneunique, correct answer.

linearDesigning Interactive VideodiscInstruction
The process of designing, writing,directing, and producing an interactive videodisc/computer lesson inwildland fire behavior is very similarto the basic design and productionof an instructional film, However,the major challenge is the integrationof various media, designing thedynamic relationship between userand the system, and working with amodular, rather than a linear medium (4).
Instructional Matrix. A contentmatrix for the instructional packagein wildland fire behavior was initially developed from a careful analysis of program goals and objectives, existing course materials,learner characteristics, and the various forms of media used withinthe disc to be selected. This matrixlists the appropriate instructionalsegments classified by topic and intended learner group in a matrixstructure. The matrix thus acts asa "map" to guide the designer increating the dynamic flowchart thatrepresents the interactive branching training program.
Interactive instruction is designedto be modular and nonlinear. withhundreds of preplanned optionsavailable to learners based on priorknowledge of their unique interests,abilities, feedback preferences, primary language ability, and leamingstyles (fig. 1).

frame, both still frames and motionsequences, all branching options,menu driven and under programcontrol, all "help" routines, all testitems, and dedicated jump forwardand review options.
The procedures used in flowcharting interactive instruction are similarto those used in any flowchartingoperation. Symbols are very nearlythe same, with a few variationsto allow for easy identification ofthe nature of the instructional frame,whether it is a still of freeze frame,or motion sequence. A sample flowchart is shown in figure 2 to demonstrate the complexity involved inthe development of an interactivelesson in wildland fire behavior.
Script, Narrative Writing, andGraphics. After the major elementsof flowchart construction are completed, scripts and narratives mustbe written, including all text, computer and quiz screens, and testitems. Special terms are used tohelp integrate the various media,and keep track of hundreds of instructional segments that will beused to individualize instruction fora variety of learners. Scripts andstoryboards are then drafted and reviewed for content, style, and feasibility; graphics, animation, andspecial effects are also planned atthis time. Formative evaluation andrevision are also appropriate atthis stage of design.
Preproduction. The preproductionphase of an interactive videodisc
1986 Volume 47, Number 3 .
is very similar to that of a film orvideotape. However, there are somesteps unique to the videodisc medium, including the mapping of the"geographical" layout of the disc,writing of the accompanying computer program, and locating the simple time code numbers for the videoframes from the master tape. Thesesteps must be completed beforethe final production and the mastering of the videodisc (4, 11).
Production details will not bediscussed, as basic production fora videodisc is almost identical tothat of other media such as videotape or film. Once a master videotape of the training materials isedited and contains all instructionalsequences, the tape is sent to oneof five mastering houses, where thevisual images and audio are transferred onto a videodisc.
Hardware and Software Considerations
Intaractive videodisc training isorientad toward the developmentof learning stations for individualand small group learning. Interactiveinstruction can take place in anylocation where an individual orsmall group can have access to acomputer that controls several peripherals, including a videodiscplayer and monitor (fig. 3 and 4).Input to the computer can bethrough a touch screen, light pen,or keyboard. The video output from
the computer, as well as video/audiofrom the. disc, appears on a singlescreen or two separate screens. Thedelivery system chosen for thisproject uses one screen, allowingboth video from the videodisc, andtext over the video, which is generated by the computer. "Windows"of video can be opened to illustratea point described by computer text,or lettering can be written over avideo image.
The hardware configuration selected for this project includes anIBM PC computer, Pioneer LDV-lOOO videodisc player, and Zenithcolor monitor. Programming is beingdone using an authoring systemcalled "Quest."
Expected Benefits
Interactive videodisc technologyhas proven to be a powerful educational tool, using computer-basedlearning systems that can dis-play high-quality video imagery,provide rapid access to images, andutilize quality audio. The individualized, self-paced format representedby videodisc instruction focuseson learner needs, rather than a--predetermined pace and sequence. Alearner is able to choose amonga variety of instructional options,and learning is directed accordingto performance and measurements ofunderstanding. Interactive videodiscallows learners to have remedial

Because of the huge storage capacity of a videodisc, beginning, intermediate, and advanced fire behaviortraining courses can be placed onone disc, allowing the learner toseek remedial help when necessaryor go on to advance material whendesired. Fire behavior simulationexercises can also be included, allowing learners to apply their knowledge of fire behavior in lifelikescenarios requiring management decisions. Such simulations are moreversatile and "transportable" thanpreviously developed fire simulators,and can be used in small or remotecenters or for individual use forreview or training. The incorporationof tutorial lessons, as well as drilland practice, test items, and information storage make interactivevideodisc an efficient, space-savingmedium for instruction and a potentially powerful training tool for firemanagers and personnel.

Other benefits of using interactivesystems include; the use of programsby either individuals or smallgroups, flexible scheduling of training, ease of transport of instructionto remote training sites, and trainingcosts much lower than for traditionaltraining methods.
Recent studies i.ll the comparisonof videodisc instruction to traditionalmethods of instruction have shown
1986 Volume 47, Number 3
numerous advantages from theuse of interactive videodisc. Suchfactors include; savings in actuallearning time, higher mastery rate,and favorable response to the medium. Other cost-related benefits areless time spent away from the job,reduced travellliving expenses fortraining, reduced need for classroominstructors, and use in remote training stations (6, 7).
