Des Plaines Fire

Department Hazardous Materials Operations Refresher

Program

Overview: Standards

• In our organization, we are trained to:

• NFPA 472 – Standard for Competence of Responders to

Hazardous Material/Weapons of Mass Destruction Incidents

• OSHA HAZWOPER (Hazardous Waste Operations and Emergency Response) standard 29 CFR 1910.120

• All DPFD personnel are trained to meet the minimum standard of the Hazmat Operations role. This role allows us to implement/support actions to protect nearby persons, the environment, or property from the effects of release of a hazardous material

Overview: Core Tasks

• Analyze the scene of a hazardous materials/WMD incident to determine the scope of the emergency

• Survey the scene to identify containers and materials involved

• Collect information from available reference sources

• Predict the likely behavior of a hazardous material

• Estimate the potential harm the substances might cause

• Plan a response to the release, including selection of the correct level of personal protective clothing

• Perform decontamination

• Preserve evidence

• Evaluate the status and effectiveness of the response

Primary Responsibilities

• Estimating the Potential Harm

• Identify a resource for determining the size of an

endangered area of a hazardous materials incident

• Using readily available reference sources, identify initial

containment and isolation zones for products identified

Primary Responsibilities

• Identification of Possible Hazard Sources

• For a given response identify what actions would be taken for a product release/leak

• Response route based on weather conditions

• Staging locations

• Product location

• Water supply options

• Possible evacuation distances

• Notification procedures for Technician Level response

Primary Responsibilities

• Predict the behavior of a material & its container

• Determine the potential consequences of container failure

and methods of determining product behavior

• Identify hazards associated with the container in a variety of

situations

• Use MSDS for product and identify basic chemical properties

DPFD Hazmat SOPs

• H:\Fire\Common\Policy\Emergency SOP's\Emergency SOP's\Hazmat\New SOPs per RRJ\HAZ-MAT Running Orders E.doc

• Communication #: 06-08-33 Effective Date: 08-29-06

• HAZARDOUS MATERIAL ALARM: An emergency involving the uncontrolled release of a hazardous substance that poses an unreasonable risk to health and safety of individuals and property.

• H:\Fire\Common\Policy\Emergency SOP's\Emergency SOP's\Hazmat

Hazmat Incident

Response Levels

• DPFD Level I: Incident that can be controlled by first

responders. No evacuation necessary beyond initial site.

Small area that poses no immediate threats to life,

property, or environment. May be handled by a single

engine company (ex. Auto leaking fuel)

Hazmat Incident

Response Levels

• DPFD Level II – Incident has greater hazard/area

involved than Level I. May pose danger to life, property,

and environment. This incident may require limited

evacuation/protective area of surrounding sites. If formal

response required, 12 technicians and MABAS would be

called. (ex. Minor accidental chemical spill at industrial

location)

Hazmat Incident

Response Levels

• DPFD Level III – Incident that poses severe danger to

life, property, and environment. May involve large scale

protective actions, etc. Incident will require MABAS

assistance as well as state/federal support(ex. Large scale

train derailment with numerous tanker cars on fire)

Routes of Exposure

• Inhalation

• Absorption

• Ingestion

• Penetration/Direct Contact

• Injection

• Radiation

Hazardous Material Health

Effects

• The acronym TRACEMP defines potential health effects:

• Thermal

• Radiological

• Asphyxiation

• Corrosive

• Etiological (bacterial infection/disease)

• Mechanical

• Psychological

Hazmat Exposure Limits

• Threshold Limit Value (TLV) – Exposure concentration

in PPM which begins to affect a person in any way

• Permissible Exposure Limit (PEL) – OSHA’s legal limit for exposure to a chemical substance

• Time Weighted Average (TLV/TWA) – Average exposure

limit over 8hr day and 40 hr work week

Hazmat Exposure Limits

• Ceiling (TLV/C) – Maximum concentration that should not be exceeded at any time

• Short Term Exposure Limit (TLV/STEL) – 15 min exposure limit concentration

• Cannot be repeated more than 4x per 24 hr period

• Should have at least 1 hr between exposure periods

• The lower the TLV/STEL, the more toxic the substance

• Immediately Dangerous to Life & Health (IDLH) – Immediate

• The concentration which poses an immediate threat to life or could cause irreversible or delayed health effects

• 3 types: Toxic, flammable, oxygen deficient

Commercial Occupancies

Containing Hazardous Materials

• Fuel storage facilities

• Gas/service stations and convenience stores

• Paint supply stores

• Plant nurseries, garden centers, and agricultural facilities

• Pest control and lawn care companies

• Medical facilities

• Photo processing laboratories

• Dry cleaners

• Plastic and high-technology factories

Site Management

• ALWAYS approach uphill and upwind if possible

• Look for possible clues to the incident upon approach

• Establish initial isolation perimeters/distances as soon as

possible (ERG)

• Establish cold, warm, and hot zones

Site Management: Public

• Shelter-in-place: Have areas affected turn off all HVAC,

close windows, etc. Stay indoors listening via radio or TV

for instructions

• Evacuation: Have people in affected areas physically

move to a safe specific location. Remember factors such

as ability to disseminate info, time involved, population at

risk, routes of travel, etc. (If in hot zone, mass emergency

decontamination may be required)

Hazmat Identification Methods

• 7 primary clues to identify a hazardous material:

• Shipping papers/documents

• Container shapes/types

• Placards/labels

• Detection equipment

• Markings/colors

• Type of occupancy/location

• Senses

Hazmat Identification Methods

• Sources for names of hazardous materials at transportation incidents:

• On-site personnel

• Shipping papers

• Material Safety Data Sheet (MSDS)

• Emergency Response Guide (requires general identification of U.S. DOT placards)

DOT Marking System

The DOT Marking System for

first responders is located in

the 2008 ERG pgs. 16-17

Once a placard is identified,

use this marking system to

establish initial containment

and isolation zones

NFPA 704 Marking System

Each diamond labeled

with a number from 0-4,

0 being least hazardous

and 4 being most

hazardous (Seeing a 4 in

any field will easily kill

you)

NFPA 704 Marking System

Blue = 0

-no health hazard

Red = 3

-can be ignited under almost

ambient temp conditions

Yellow = 0

-Normally stable, even under

fire conditions, not reactive

with water

White = blank

-No special considerations

NFPA 704 Marking System

Blue = 0

-Exposure would cause irritation

with only minor residual injury

Red = 4

-Flash point below 73 F

Will readily ignite at atm pressure

Yellow = 0

-Normally stable, even under

fire conditions, not reactive

with water

White = blank

-No special considerations
