INSTALLING IMPACCT ACCESSORYSafety Tips to Remember during Applicationa. If the area where public may be affected, ensure they have been notified. In critical areas hydraulically pressed sleeves may have to be used.b. Do not use or handle any explosives if a lightning storm is threatening. Also, keep clear of secured magazines during this condition.c. When installing sleeves, be sure all equipment and fire hazards have been removed to a safe distance. This includes welding equipment, torches, grinding operations, generators, compressors and electrical tools and extension cords. No other work is permitted in the blast site. Only those necessary to the operation should have access.d. Do not cut shock tube or detonating cord with wire cutters. Avoid grinding of explosives between two metal parts (like scissors or shears). One good method is to use a sharp knife or razor knife (box cutter) and cut on a wood or plastic surface. A special cutter tool (shown later in this manual) that uses utility knife cutting against a plastic strip is ideal. Also, do not cut against any hard (metal) or abrasive (concrete) surfaces. e. Blaster-in-Charge (BIC) should keep the Shock tube initiator in their control during application procedure. Only when the blast area is clear and IMPACCT installation is complete shall the starter be connected to the shock tubef. The blast area must be cleared before the lead-in-line (shock tube) is deployed from the blast site. Verify access to the blast area is blocked and all personnel and equipment are in a safe location.g. Always check for misfires before reentry into the blast site. This is especially true when firing multiple accessories at the same timeh. Stay clear of all explosive smoke. It can contain toxic gases and can be harmful to breathe.

Getting Started!Assign Authority The most important step needed before starting the installation is designating a “blaster-in-charge” (BIC). The BIC person is responsible for ensuring that all safety guidelines are followed and has the authority to direct the activities necessary to ensure the safety for all parties involved with the IMPACCT installation. The BIC has total authority at the blast site.

Identify the clearance area.One of the greatest challenges, which a blaster faces in construction blasting, is to accurately determine the bounds of the blast area. The blaster in charge must survey the area and set the bounds necessary to ensure safety. The recommend minimum distance for the IMPACCT product is 300 feet for individuals, personal vehicles and equipment (especially with glass). The BIC can be as close as 200 feet if wearing proper personal safety gear (ear and eye protection and a hard hat) AND he is behind a substantial barrier. A substantial barrier would be something like a large tree, rock, dumpster, etc. In any case, any person within the 300 foot radius of the blast should not be “in line of sight” of the accessory.

Removing employees from the blast area

THE BIC SHOULD BE AT LEAST 200 FEET AWAY BEHIND COVER WITH ALL OTHER PERSONAL AT LEAST 300 FEET AWAY FROM THE IMPACCT ACCESSORY WHEN IT IS DETONATED.

The blaster is responsible for ensuring that all employees are cleared from the blast area and removed to a safe location prior to any scheduled blasting. All equipment in the blast area should be removed to a safe distance. An accounting must be made for all employees to make sure that no one is left behind in the blast area. Arrangements should be made to ensure that no one can return back to the blast area prior to sounding an “all-clear” signal.

Access control To prevent unauthorized entry, guards should be posted at all access points leading to the blast area. Guards should physically remain at their duty stations until an “all-clear” signal is sounded. The guards must be attentive at all times to ensure the security of the blast. Additionally, barricades may be erected with signs in bold letters such as “Warning! Explosives in Use, Blasting Area, Do Not Enter” may be posted at all access points.

Effective communication Effective communication is a key element in preventing blasting injuries. Failure of effective communication may result in fatalities and serious injuries. Workers and visitors should be informed about the blasting signals, evacuation procedure, location, and timing of a scheduled blast. Audible signals, such as sirens, whistles, or horns mounted on a vehicle, are used in many operations to caution employees, visitors, and neighbors about a scheduled blasting event. Enough time should be provided to facilitate orderly evacuation of all personnel, whose presence is not required, from the blast area.

Warning signals before blastPrior to the blast, give at least 6 short signals with either an Air or Car Horn with one second intervals. Then wait at least 2 minutes and then initiate the charge. Do not return to the blast area until the BIC has initiated a 5 second “all clear” signal and declared the blast area safe. The BIC should inspect the area before giving the all clear signal.

The BIC is ultimately responsible for ensuring that the blast area clear even though he has sounded the blast alarm.




STORAGE The blaster is responsible for ensuring that all explosive materials, detonators,, detonating cord, accessories with detonating cord, shock tube, must be stored in magazines constructed and located in accordance with federal, state and local regulations. Magazines should be kept locked at all times except for inspection, inventory, or the movement of explosive materials in or out of the magazine.

Remember, detonators can never be stored with detonating cord (or accessories with detonating cord) in the same magazine. Bulk shock tube (without detonators) should be stored with your detonating cord. If your have other explosive products unrelated to the IMPACCT Accessories, contact the manufacture or the ATF to determine storage compatibility.

The shot-shell primers are not regulated by the ATF and are not required to be stored in a magazine. In fact, they should not be stored in the magazine with either the caps or the detonating cord. The primers are sensitive to moisture and must be kept dry. An ideal storage method would be to keep them in a small plastic, waterproof container. You can find these in some sporting goods department for camping supplies. Look for the containers with an O-ring for cell phones and PDAs. If possible, keep the primers in their original packing trays with in the water tight container. Although not as powerful as detonators, they are dangerous and should be locked up and away from children.

Waiting Period in the event of a MisfireIf you have a misfire with the IMPACCT Accessory using the recommended and authorized procedures described here, wait a minimum of 30 minutes before reentering the blast area, unless the manufacturer recommends additional time. Entry to the blast area should be restricted during the waiting period. The shock tube initiator should be removed and from the shock tube and secured during this time. It is acceptable and recommend to attempt to re-fire the shot if it is suspected that the reason for the failure involves the initiation device being held by the BIC. Be sure to follow all safety procedures when refiring the shot, especially access control. It would be easy for someone to wander into the restricted zone while the BIC was trying to correct the problem and refire the shot. Always cut off about 3 feet of shock tube to expose a fresh end before reattaching the initiation device.

Misfire Resolution Procedures After the appropriate 30 minute waiting period after the last attempt to fire the shot, the blaster-in-charge (BIC) and an absolute minimum number of authorized, competent, and experienced personnel required to assess the situation may enter the blast area. The BIC should develop a plan for resolving the misfire and communicate that plan to essential personnel before work begins.

Clean UpAll boxes and material associated with the explosive material must be destroyed in safe manner. Prior to leaving the site, the BIC is responsible for waste disposal of this material. OHSA (Occupational Health and Safety Act) requires that empty explosive packaging be burned. If possible and permitted, burn the empty boxes on site. If this is not possible, burn off site or otherwise have them incinerated. In any case, do not reuse the boxes for anything or put them in a common garbage, dumpsters or recycling bins. This is for two reasons. First, someone may recover an explosive box and use it for another purpose. This could cause and emergency response if the package is discovered by someone. Secondly, certain explosive may contaminate the package with explosive residue. Although the IMPACCT product is unlikely to do this, casual reuse of explosive packaging is never a good idea.

One possible exception of the above is the repacking of an identical explosive product that was in the same type of packaging. For example, if you need to replace a damaged box. In this case, you must transfer the date codes, description, etc. on the outside of the box to match item in the box.

Installation Procedure for AFL IMPACCT Compression Joint – ACSRInstallation of the IMPACCT cannot be performed during inclement weather and the conductor must be free of moisture.

Prior to making connections, conductor and accessory “bore” must be clean. Regardless of conductor condition, the strands need to be cleaned with a wire brush or abrasive cloth. Check accessory “bore” for foreign particles, removing if present.

Straighten out several feet of conductor removing set caused by reel. Ensure conductor end is in good condition for use. If conductor is to be cut, use tape or tie wire to temporarily retain the conductor’s strands in a tight configuration, remove when appropriate from assembly.

2.0 Procedure for Attaching Detonator & Firing the IMPACCT AccessoryThe IMPACCT Accessory should be ready for install at this point!

The following procedures describe the steps to attach a shock tube detonator (blasting cap) to an IMPACCT Accessory. After properly preparing the accessory as described earlier, the following steps are exactly the same for all of the products.

Note: Except for a few very important and specific points, all of the many safety procedures are not addressed here. Please refer to the previous sections for general explosive safety concerning handling, transportation, storage, etc. for these potentially dangerous products.

Also, the following is not intended to substitute for hands on personal training which is required by the manufacture and by law to use these products. If you have not been properly trained in person by the manufacturer of the IMPACCT Accessories, THEN STOP AND DO NOT CONTINUE.

Before performing the following steps, the IMPACCT Accessory to be fired should have been completely prepared. The area should have also been cleared of persons, equipment, etc. in preparation for the blast. Please see the section on pre-blast procedures for detailed instructions.

Step One:Preparing the DetonatorDetonators with Shock Tube, also called Shock Tube type blasting caps, are the type of detonators authorized to be used with the IMPACCT Accessories. Do not use electric or fuse type detonators with this product. Shock Tube Detonators (STDs) are inherently safer than other kinds of blasting caps for this application. For more information on Shock Tube and detonators in general, please refer to the introduction section for explosives.

STDs are always manufactured with some length of Shock Tube already attached. If the STDs are purchased with a relatively short length of tube (for example: 8 to 24 feet), then more tube must be spliced onto the detonator’s tube in order to allow the operator to be a safe distance away from the blast.

The package shown in Figure 1 contains 25 each, STDs with 16 foot long tubes. These are DOT Class 1.4S, which means that they can be easily transported. Please see the section on explosives transportation regulations for more information on this subject.

ATTENTIONEXPLOSIVES - DANGEROUS

If you have found this product unattended on a job site, contact your supervisor immediately. If you have found this product outside of a job site, do not touch it and contact your local law enforcement agency immediately.

Fig. 2 Fig. 3 Fig. 4

Also, note that these are “0” (zero) delay blasting caps. This means they have no delay, thus they are “Instant” blasting caps. These instant blasting caps are preferred, but delay caps may used under most circumstances. If you need more information on this subject, please contact the manufacturer.

As shown in Figure 5, the end of the Shock Tube opposite the blasting cap is sealed at the factory.

ATTENTION: DO NOT ATTACH THE DETONATOR TO THE ACCESSORY UNTIL JUST BEFORE BLASTING. MAKE SURE THE DETONATOR IS NOT ATTACHED TO THE ACCESSORY BEFORE CONTINUING

This sealed end must be removed before it can be spliced onto a longer tube. The cutters shown below (Figures 6 and 7) are the preferred type. These have a replaceable blade and cut cleanly on a plastic surface. The cutter recommended is a “Superknife Cutter” available from Omni Explosives at 800-277-6664.

A sharp razor knife can also be used to cut the tube (see Figure 8). It is best to cut the tube against a wooden or plastic surface. Shock Tube itself is very insensitive and it is almost impossible to initiate without a very strong shock from another explosive. Cutting, fire, moderate impact and sparks will not cause the tube to fire. The main reason to cut against a wood surface is simply to keep your cutter sharp. However, as with all explosives, treat them with respect. The detonator, on the other hand, WILL explode if subjected to a fire or strong impact. Keep the detonator away from your body and in a safe place when working on the Shock Tube.

DO NOT DRIVE OVER OR STEP ON SHOCK TUBE. IT CAN BECOME DAMAGED AND CAUSE MISFIRES.

Note: Shock Tube is manufactured in various colors. The green and yellow tube shown here are exactlythe same, just different colors.

Fig. 5 Showing sealed end of Shock Tube on the opposite end of the tube from the blasting cap.

Figure 6Cutting off the sealed end of the Shock Tube

Figure 7 Preferred cutting tool for Shock Tube




In any case, Shock Tube should be cut with a sharp blade to make a good square, clean cut. Never cut Shock Tube with wire cutters scissors or any other tool that will crush and deform the plastic. Figure 9 shows the WRONG way to cut Shock Tube. Doing this will cause misfires.

Also, after cutting, you need to splice the joint immediately. Do not get the cut ends of the tube wet. The side the plastic tubing is waterproof. If water or another liquid enter the cut end of the tube, it will misfire.

Bulk shock tube comes on a roll, normally 2500 feet as shown in Figure 10. It is usually best to go ahead and reel out the length of shock tube off the bulk roll from your work area to the safe area before continuing. The safe area is where you will be when you initiate the blast. See the section on safety to determine this distance, but it will usually be about 200 to 300 feet away from the IMPACCT Accessory.

After cutting your length of tube from the bulk roll, seal all cut ends of the tube with the rubber tips provided or with electrical tape. Be sure to return the unused shock tube to your day box or magazine if it is not to be used again in the immediate future.

In order to splice the detonator’s shock tube to the long tube, you will need a clear plastic splicer. It looks like a small piece of aquarium tubing, which is basically what it is. Be sure to use the ones provided, as they are a special size that is not readily available at the hardware store. Follow the following steps which should be self explanatory:

Step 1. Insert the first tube in the splicer, Figure 11.Step 2. Insert the tube to a depth of at least 1/3 the splicer length, Figure 12.Step 3. Insert the second tube the same depth as the first, Figure 13.Step 4. Finished Splice, Figure 14 (The tube ends should not touch).

Figure 9NO! DO NOT cut Tube like this.

Figure 10 Roll of Shock Tube, 2500 feet long. No detonator, just Shock Tube.

Fig. 11 Fig. 12 Fig. 13 Fig. 14




After pushing both tubes into the splicing tube, there will be a gap as shown in Figures 14 and 15. It is neither necessary nor desired to push the Shock Tubes together until they touch in the middle, Figure 15.

Note: Before splicing, it is never a bad idea to cut a foot or so off the free end of the spool’s tube in case the end of the tube has been contaminated.

So that the splice will not come apart easily, make a stress relief by means of electrical tape (Figure 16) or by tying an overhand knot in both tubes. Tie the knot snug, but don’t over do it. The Shock tube will fire through the knot without a problem.

In most cases, a more desirable way to handle the blasting cap situation is to order your STDs with long lengths of Shock Tube already attached. By doing this, you avoid having to splice the tubes. Another benefit is that there is one less inventory item to deal with. These STDs can be had with any length of tube attached, 200 to 300 feet being typical. They are supplied on a fiberboard reel, so deploying the tube is very easy. See Figure 18.

Step Two:Attaching Detonator to Accessory

ATTENTION: DO NOT ATTACH THE DETONATOR TO THE ACCESSORY UNTIL JUST BEFORE BLASTING.

AT THIS POINT, THE ACCESSORY SHOULD BE 100 PERCENT PREPARED AND PRE-BLAST PROCEDURES, SEE APPENDIX I, SHOULD BE AS COMPLETE TO THIS POINT.

ALL NON-ESSENTIAL PERSONNEL SHOULD BE VACATED FROM THE BLAST ZONE.


THE SHOCK TUBE INITIATOR SHOULD NOT BE CONNECTED TO THE OTHER END OF THE SHOCK TUBE. DO NOT ALLOW ANYONE TO BE NEAR OR TOUCH THE OPPOSITE END OF THE SHOCK TUBE WHEN YOU ARE IN CLOSE VICINITY OF THE EXPLOSIVE ACCESSORY AND BLASTING CAP.

Until this part of the procedure, the Stock Tube Detonator (STD) should be kept in a protected and safe place away from the explosive accessory. Regardless of the type of accessory you are using, all IMPACCT products are wrapped with a linear explosive called detonating cord. It is essentially an explosive rope. The cord is usually orange or yellow, but it could be another color. The STD is used to detonate this explosive in order to compress the joint around the cable.

The STD is easy to attach to the accessory. There will be a label on top of the detonating cord indicating where to put the detonator as shown in Figure 19. Figure 20 shows the detonator being attached to the accessory with electrical tape. The tip of the detonator should be near the tip of one of the arrows. It does not matter which direction the detonator is pointing, just as long as it is parallel to the accessory.

Only the front half of the detonator contains explosive. This is the part of the blasting cap that actually explodes and communicates the detonation wave to the accessory. Therefore, it is very important to secure this section of the detonator firmly with the electrical tape. See Figure 21.

The last step is to apply another round of tape for a stress relief, see Figure 22. This will prevent movement and damage to the STD if the tube is accidentally pulled.

ATTENTION: AFTER THE DETONATOR IS ATTACHED TO THE ACCESSORY, ALL PERSONS SHOULD LEAVE THE AREA OF THE BLAST SITE AS SOON AS POSSIBLE.

FOLLOW YOUR BLASTING PROCEDURES, PREVENT ALL UNAUTHORIZED PERSONS FROM ENTERING THE PREDETERMINED SAFETY PERIMETER OF THE BLAST SITE.

Step Three: Loading the Shock Tube InitiatorThere are several different kinds of “starters” or “initiators” for use with shock tube. Two of the most common are electronic versions that utilize a powerful spark and others that use a common shotgun shell primer. Of these two, it is recommended that a shot gun primer type be used with the IMPACCT Accessories. Without going into details, these have been found to be more reliable and less expensive. One type is shown in Figure 23 along with a box of primers

The following captions on the figures below will explain the procedure for loading a firing the Shock Tube Initiator Device. If using another type of initiator, follow that manufacturer’s instructions.

When reassembling the device, make sure the primer does not fall out of place (Figure 25). It may help to turn the device downward while tightening. Also, make sure the brass part holding the primer “bottoms out” before the lock ring touches. Tighten the lock ring last to make sure the primer holder does not move. More complete instructions will be included with the particular device you use.

ATTENTION: THIS IS THE LAST STEP BEFORE FIRING SHOTDO NOT PROCEED UNTIL YOU HAVE COMPLETED YOUR PRE-BLAST CHECK LIST, SEE APPENDIX II,

AND YOUR SITE INSPECTION CHECKLIST, SEE APPENDIX III

UNTIL YOU ATTACH THE SHOCK TUBE TO THE INITIATOR, IT WOULD BE VERY UNLIKELY HAVE AN ACCIDENTAL DETONATION

MAKE SURE THAT THE BLAST SITE IS SECURE AND CLEAR BEFORE YOU ATTACH THE SHOCK TUBE TO THE INITIATOR

IF YOU HAVE AN UNEXPECTED DETONATION, YOU WANT IT TO BE AN EMBARRASSING SURPRISE, NOT A DEADLY DISASTER

Fig. 25 Place a standard #209 Shotgun Shell Primer into the holder.

Fig. 26 Primer shown in correct position.

Fig. 27 Double check the safety pin before reassembly




Step Four: Firing the Shot

Start by loosening the knurled brass collet on the front part of the initiator. Take the Shock Tube and cut a fresh end before inserting it into the initiator. Push it into the device as far as it will go, but not past the vent holes located above the lock ring. Tighten the collet nut firmly to retain the Shock Tube.

ATTENTION: THIS IS THE LAST CHANCE TO CHECK THE AREA BEFORE FIRING THE SHOT


ASSUMING EVERYTHING IS RIGHT, YOU ARE READY TO FIRE THE SHOT.

YOU SHOULD BE WEARING EYE AND EAR PROTECTIONFROM THIS POINT FORWARD.

Before you remove the safety pin from the initiator, make sure the firing pin thumb bolt is in the “cocked” position. If the firing pin if resting on the safety pin, the device will fire upon removal of the safety pin.

To fire the shot, simply pull the bolt back with your thumb, move it over and “snap” it. Do not “ride” it down with your thumb, as it may cause a light strike on the primer. If it does not fire, try again. If still does not work, follow misfire procedures.

IF YOU HAD A MISFIRE, FOLLOW YOUR MISFIRE PROCEDURES.

The following is abbreviated version for reference only. You need to follow your detailed misfire procedures

1) Start by securing the Shock Tube Initiator, then follow the procedures in this guide in exactly the reverse order until you find the problem or secure the explosives to a safe condition. 2) Wait at least 30 minutes before approaching the accessory since the LAST time you attempted to fire the shot. 3) Secure the area until the Blaster in Charge declares it safe and clear4) Upon arriving at the accessory, remove and secure the detonator before doing anything else.

Step Five: After the ShotIF YOU HAD A SUCCESSFUL SHOT, PROCEED WITH YOUR POST BLAST PROCEDURE, SEE APPENDIX IV.After detonation, remove the debris from accessory and cable. Clean surface of Accessory with cleaner and cloth to remove powder residue. The Joint should be straight in appearance. Its surface should be smooth and continuous without depressions.

Note: A depressions at location of “Core sleeve” and Conductor interface (See step 4)would indicate the conductor had pulled away form “Core sleeve”. This condition would lessen the holding strength of the accessory and it should be considered for removal.

APPENDIX IIMPACCT Pre-Blast ProcedureThe following procedures are to be employed when using the explosive IMPACCT Accessories. Site specific procedures will need to be implemented due to geographic, demographic, meteorological variables as well as the existence of commercial and residential buildings in the vicinity.

DefinitionsBlasting Zone: The general area within the job site where blasting is to be conducted. This zone would include, but not be limited to, the area where explosives are being handled, used, temporarily stored (day boxes), and/or loaded and unloaded from vehicles.

Restricted Zone: This is the area within the blasting zone where all persons except the Blaster in Charge (BIC) are forbidden to be. The Restricted Zone rules are to be in force anytime the detonator is attached to, or being attached to the accessory. No persons are permitted to return to the Restricted Zone until the “All Clear” signal is given by the BIC. The Restricted Zone is typically a 300 foot (minimum) radius from the IMPACCT Accessory being fired.

Shot or Shot Firing: The detonation of an IMPACCT Accessory.

Blasting Operations: the detonating (firing) of the IMPACCT Accessory.

Transients: visitors, vendors, non-employees, etc.

During the week before the blasting is to commence, the Blaster in Charge should verify that all State, Local and Federal rules and regulations will be satisfied. This includes licenses, permits, etc. for the company, the Blaster in Charge as well as any handlers or assistants that may be required. The Blaster in Charge should contact the local Fire Department, Sheriff’s Department and Police Departments within the jurisdiction. If in doubt, contact them. One of the most important pieces of information to obtain is the contact number for the dispatch center of each agency. The dispatchers will need to be called the morning of each day blasting operations will be conducted. Just ask them how they would like to be notified, as it will vary from place to place. The importance of this cannot be overstated.

If there are commercial or residential buildings in the vicinity, it is highly recommended that someone contact them and explain what is going on. A simple flyer with a description of the activities, what to expect, time frames, etc. will head off most potential complaints. Be sure to include contact information in case the blasting operations cause any problems.

Each Job site shall establish procedures to ensure that site personnel and transients are not exposed to fragments or excessive blast overpressure from a shot. In establishing these procedures, the following guidelines shall be considered:

• During blasting operations, personnel access to each site shall be controlled. Unattended roadblocks, gates or doors used to prevent personnel from entering the danger zone during a shot should be interlocked or locked with specially controlled keys.

• Before shot firing, all firing site personnel and visitors shall be accounted for and in a safe place.

• A visual inspection of the Restricted Zone shall be performed immediately before each shot or series of shots as applicable, to ensure that no transients or other personnel are present.

• The Restricted Zone shall be free of service personnel (e.g., telephone repairmen, surveyors, or road maintenance crews, etc.) during blasting operations. The control point shall notify service personnel of the specific requirements under which they may safely work in the area when blasting is not in progress. In addition, the control point shall notify firing site personnel of the presence and location of service personnel in their areas.

• Clearance for a firing a shot or a series of shots shall be coordinated with all other sites and other areas that could be affected. A warning shall be provided to every affected area immediately before each firing.

• Detonation of very large explosive shots or numerous smaller shots may result in hearing damage and may exceed the OSHA allowable limits for impulse noise. Perform a noise evaluation of these activities to ensure that adequate hearing protection is provided to those involved.

• During blasting operations, all personnel assigned to the test area shall be continuously alert for movement of personnel, vehicles, and aircraft. Shot firings often create hazardous conditions for aircraft operating in the airspace near the Restricted Zone. If this airspace is subject to air traffic, precautions shall be taken to ensure that the airspace is clear of traffic at the time of firing.

• Each Blasting Zone shall establish personnel limits based on the number of people actually needed to conduct an operation and the number of casuals that should be present. The Blaster in Charge at the firing site shall enforce these personnel limits.

• Detonation of explosives can result in personnel exposure to toxic decomposition products such as carbon monoxide, and nitrogen oxides It is good practice to allow the detonation cloud to disperse before leaving protective area. The Restricted Zone distances are normally adequate to allow cloud dispersal and protect outside personnel from excessive exposure.




APPENDIX IIIMPACCT Misfire ProcedureIf you have attempted to detonate the IMPACCT Accessory and it did not explode, then you have had a misfire. There are many reasons for misfires. Some are easy fixes, some are not so apparent. Most will be caused by user error, but faulty products or equipment is sometimes to blame. It is important that you follow the steps listed below to correct the situation without to avoid accidents.

First, do not allow anyone into the blast zone until the Blaster In Charge (BIC) has given the all clear signal. The BIC is the only person who is allowed to perform any of the following steps. The procedure below is basically the reverse of the procedure used to fire the IMPACCT Accessory, along with a little common sense.

1) When you attempted initiate the charge, did the shotgun primer fire in the firing device? (You will know if it fired or not, it makes a loud “pop” if it fires)

a) Yes, proceed to step 2

b) No, it did not flash or I am not sure. Cut away about 3 feet of shock tube, replace the primer and try again. Watch the tube to see if it flashes. Repeat 3 times, or until you see the flash or the accessory explodes.

Still nothing? About 3 feet from the firing device, cut out a 6 inch piece of shock tube. Put one end of the 6 inch piece of shock tube to your lips blow while holding the other end a fraction of an inch from the palm of your hand. If you see a silvery powder appear on your palm, then the shock tube has not fired. This probably means that the firing device bore is blocked (not uncommon), or the shock tube is defective (very rare).

If you blow the tube and nothing comes out, this probably means that the tube has fired. In bright sunlight, it is sometimes hard to see the flash of the tube. Proceed to step 3.

3) Unload the firing device (remove the primer) and disconnect the firing device from the shock tube. Secure the firing device on your person or lock it away so nobody else has access to it.

YOU MUST WAIT AT LEAST 30 MINUTES FROM THE LAST ATTEMPT TO FIRE THE ACCESSORY BEFORE YOU START WALKING TOWARD

THE CHARGE.

4) After waiting 30 minutes from the last attempted firing, the BIC should walk toward the charge alone. While walking forward, hold the shock tube lead-in-line loosely in your hand. As it runs through your hand, feel for any cuts, nicks, bulges or thin spots in the tube. If a defect is discovered, check to see if the line has fired by blowing into a 6 inch piece as previously described. If you find that it has not fired at some point, another blasting cap can be attached to the shock tube with electrical tape. You can then retreat to your safe area and fire the charge.

5) As you arrive at the IMPACCT Accessory, look to see if the detonator (blasting cap) at the end of the shock tube is still intact in its original condition. If the detonator is still attached to the Accessory, immediately remove it and secure it in a safe place away from the Accessory and other explosives.

6) At this point, the Accessory is safe and others can be allowed into the area if needed. If you want to attempt to fire the accessory again, then keep the blasting clear. Follow the firing procedures from whatever point is appropriate.

Summary:

Try to again to fire the charge. See if you can find the problem at your safe area.

If you have to return to the accessory, remove and secure the firing device and wait 30 minutes after the last attempted firing.

Upon returning to the accessory, immediately remove and secure the unfired detonator. The Blaster In Charge is the only person to ever be in within the restricted blasting area when the detonator is attached to the accessory.

Find the problem, regroup and follow the firing procedures as needed.

Note: If multiple accessories are being fired simultaneously (or sequentially) make sure ALL accessories have detonated before the all clear signal is given. If one or more accessories has misfired, then follow the procedures above until the situation is resolved.

Appendix IV: IMPACCT Post Blast Procedures1) After the blast, the Blaster in Charge can give the “All Clear” signal. If multiple shots are being fired simultaneously or sequentially, the BIC must confirm that all of the IMPACCT Accessories have successfully detonated. If not, then misfire procedures must be followed. BIC must wait for all smoke and dust to clear before “All Clear” signal is sounded.

2) Workers can return to blast area after all clear signal has been given. Release road access guards. Resume work and business activities

3) Call or otherwise notify Sheriff or Fire Department as needed or as required.

4) The Blaster in Charge must complete the Blaster’s Log Sheet. Log must be completed in its entirety. Enter blaster’s name. Enter date. Enter time of blast. Enter name of worksite or project. Enter specific location of blast. Describe weather conditions, to include clouds cover, temperature, etc. Enter quantity, type, date code and/or serial number of accessories fired (detonated). Also record quantity, description and date code of blasting caps and shock tube used for each blast. Enter time of detonation. Note any misfires or other abnormal events. Blaster’s log must be filed and distributed according to policy.

5) Before leaving the worksite: Gather and dispose of ** used shock tube. Gather and dispose of ** any containers and packages that previously contained explosive products. Police the area for any “live” blasting caps (detonators), shock tube or other explosive items that may have accidentally set aside or dropped (see #6 below). Account for all equipment including firing devices, primers, etc.

** Follow accepted disposal procedures described elsewhere.

5) Return unused explosives to inventory and make appropriate entries in ATF daily magazine inventory record book. This includes day boxes (temporary) and permanent (overnight) magazines. Note: no explosive should have been left out of the day box during blasting operations.
