Study Notes

Reporting Incidents

OSHA reporting: 8 hours for death, 24 hours for hospitalization, loss of eye, or amputation
DOT reporting: death, hospitalization, property damage over $50,000, public evacuation over 1 hour, or transport artery closure over 1 hour

Explosive Types

Mechanical, nuclear, electrical, and chemical
Chemical explosives: a mixture of materials that can cause an explosion
Chemical explosion: when a compound is ignited by heat, shock, impact, and/or friction

ATF Classification

High explosives: detonate rapidly, creating a supersonic shock wave (e.g., TNT)
Low explosives: deflagrate slowly, creating a subsonic shock wave (e.g., black powder)
Blasting Agents: a chemical mixture of fuel and oxidizer, not classified as an explosive (e.g., ammonium nitrate/fuel oil)

Explosives Information

Primary explosives: very sensitive to impact, friction, heat, static electricity
Secondary explosives: less sensitive, may need a Primary explosive to detonate
Tertiary explosives: need a Primary and/or Secondary to be set off

Safety Precautions

Minimize use, quantity, and personnel present (Min Min Min)
Proper PPE (personal protective equipment) must always be used
Non-static clothing: avoid nylon or wool
Minimize people in the test area
Test chamber design: explosives cannot be actuated with the door open

Fire Procedures

If no explosives or magazine involved, attempt to put out the fire safely
Leave room, trigger alarm, contact fire department, and have someone meet them

Improper Ignition Procedures

Flame-resistant lab coat, heavy gloves, and place spent igniter in a non-static container
Spray pyrotechnic material with water, wipe contaminated surfaces, and place contents in a sealable, non-static container

Explosive Misfire Procedures

Evacuate the area, wait at least 1 hour, and remove the unexploded item with long-handled tongs and place in a non-static generating container filled with water
Soak for 48 hours, then dispose of the item
