UN 0084
Class: 1
Placard type: Explosive 1.1D
ERG: Guide 112 (check current ERG)
Isolation: ERG 112: Initial isolation 500m in all directions. For fire involving explosives, evacuate 1600m radius and fight fire from maximum distance or use unmanned hose holders. Consider evacuation for large quantities.
Chemical & Response Details
| Also known as | Type D blasting explosiveClass 1.1D explosiveCommercial blasting agentHigh explosive blasting compound |
| Appearance | Varies by formulation; typically solid materials ranging from crystalline powders to plastic putty-like consistency. May be various colors (tan, white, yellow) depending on composition. Often odorless or with slight chemical odor. |
| Flash Point | Not applicable (explosive solid) |
| Boiling Point | Not applicable (decomposes/detonates) |
| Vapor Density | Not applicable (solid) |
| Water Reactivity | Generally stable in water, though some formulations may be sensitive to moisture. Do not use water on burning explosive. |
| Extinguishing | Do not attempt to extinguish burning explosive; evacuate and protect exposures only. If fire has not reached explosive, use water fog from distance. |
| PPE | ⚠️ Level A required for spill response; full structural firefighter protective clothing provides limited protection. Remote handling mandatory. SCBA required at all times. |
| Isolation | ERG 112: Initial isolation 500m in all directions. For fire involving explosives, evacuate 1600m radius and fight fire from maximum distance or use unmanned hose holders. Consider evacuation for large quantities. |
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.
