Disposal Procedures Flashcards
When should deteriorated dynamite be moved by hand?
When the area cannot accept a detonation, protective measures cannot be utilized, and some form of life threatening situation exists
Why should gasoline never be used to enhance a fire?

What is the preferred method of disposal for most high explosives?
Disposal by detonation
What is a safe distance for locating a demo area away from an inhabited building?

Which disposal option is reasonable for desensitized product?
Open Burn
What measure ensures safer, more efficient disposal operations?
Mandatory Safety Briefing
When should non-emergency disposal operations be accomplished?
Daylight hours
What are the four factors of consideration for disposal operations?
Safety, Environment, Logistics, Security
What is the minimum separation for a personnel shelter during demolition operations?
300 feet
What considerations are taken into account for setting range limits?
Noise, Ground Shock, and Air Shock Waves
What are the distances to keep explosive material away from disposal work in progress?
Excess of >25lb not less than 150 feet, 50lb see CFR29
To re-use a burn hole what must you do?
Wait 24 hours or soak with water and wait 12 hours
What are the Disposal Methods?
Detonate in place, TRANSPORT AND DETONATE, buried detonation, burn in place, TRANSPORT AND BURN, transfer, neutralize
What are the methods for destroying Good explosives?
Detonation, Function as designed, Burning
What does the EPA recommend for burning dynamite?
Burn Pans
What dangerous product forms on copper caps?
Copper Azide (do not open boxes)
What are the classes of fireworks?
Class “C” 1.4g (Common Fireworks), Class “B” 1.3g (Special Fireworks)
What size of an area should be cleared of combustible materials around the demo pit?
An area 200 feet in radius
Which procedure In a bomb technicians scope of practice is the most hazardous
Disposal with disposal of fireworks being the most deadly
When can the emergency threat exemption be utilized
In the presence of an imminent threat to life
When should non-emergency disposal procedures be conducted
During daylight hours
Considerations for selection of a disposal site
Safety, logistics, and security
Safety distances for a disposal site
- 200ft radius clear if combustibles, vegetation, and bunker
- 300ft from storage bunker and shelter with frontal and overhead protection
- 2400ft from all inhabited or occupied dwellings
Range limit
Limits the amount explosives which can be detonated in your disposal area.
You are never to exceed range limit
Wait times for “hot hole”
24 hours from end of fire
Or
12 hours from soaking hole with water
Distance of Storage of explosive materials
25lbs or less - 50’ from work in progress
25-50lbs - 150’
50lbs+ - use distance chart
Material used for neutralization of ANFO
Water, which causes separation of components
Material used for neutralization of Dynamite (nitroglycerin)
Diesel fuel, which causes desensitization (less sensitive to heat shock and friction). Must be reapplied.
Things which should never be done when conducting a disposal by burning
Never use gasoline
Never extinguish the fire
Disposal by burning of black powder requires a trench of which width
2” wide
When disposing of a pipe bomb, what are the minimums for explosives
1.5 of explosive or a shape charge of detonation velocity of 4000 meters per second (13,200 FPS)
