    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

    Shipping Actuators or Airbag Assemblies

    • Airbag assemblies: UN Number - 3268, Proper Shipping Name - Air Bag Inflator, Transportation Hazard Class - 9, Hazard Label - Safety Devices, Electrically initiated

    Initiator Disposal

    • Unused initiators: contains Perchlorate, classified as D00S RCRA hazardous waste
    • Used initiators: most likely has Perchlorate residue, perchlorate and its salts

    Massachusetts Regulations

    • Explosives Certificate of Competency, Limited to Research and Development
    • Limited to 50 lbs / 22.7 kg of explosives
