Chemical & Response Details
| Also known as | Explosive boostersDetonating boostersPriming charges with detonatorBooster explosives with initiator |
| Appearance | Solid explosive charges combined with detonating devices, typically cylindrical or shaped blocks of high explosives (often yellow, tan, or white depending on composition) packaged with attached detonators. |
| Flash Point | Not applicable (explosive material) |
| Boiling Point | Not applicable (decomposes explosively) |
| Vapor Density | Not applicable (solid explosive) |
| Water Reactivity | No significant reaction with water, but water should not be relied upon for fire suppression |
| Extinguishing | DO NOT use water or foam on burning explosives; evacuate area immediately and allow to burn if safe to do so |
| PPE | ⚠️ Minimum safe distance — do not approach; if intervention required before fire, Level A with blast-resistant shelter; SCBA mandatory; bomb disposal personnel only |
| Isolation | ERG 112: Isolate 800m (1/2 mile) in all directions; evacuate 1600m (1 mile) if fire; mass explosion hazard affects entire area |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Common hazards (high level)
- Mass explosion hazard — entire load may detonate simultaneously.
- Severe blast overpressure and fragmentation.
- Sensitive to heat, shock, and friction.
- Secondary fire and debris hazard.
First actions (field-minded)
- CALL 911. Then call emergency response telephone number on shipping paper.
- Establish large isolation zone — minimum 500 meters in all directions.
- Stage upwind, uphill; limit personnel to essential responders only.
- Request Hazmat + law enforcement + additional resources immediately.
- Do not fight fire — evacuate and isolate; let burn if no life safety risk.
- Protect exposures only if safe and directed by command.
- Consult current ERG Guide 112 and follow SOP/SOG.
