UN 0186
Class: 1
Placard type: Explosive 1.3C
ERG: Guide 112 (check current ERG)
Isolation: ERG 112: Initial isolation 500m in all directions; if fire or cargo involved evacuate 1600m radius; protect from heat and ignition sources
Chemical & Response Details
| Also known as | Rocket motor assembliesSolid propellant rocket motorsRocket propulsion unitsRocket engines |
| Appearance | Metal cylindrical assemblies containing solid propellant fuel, typically gray or black in color. Contains composite propellant materials with oxidizer and fuel binder in a solid matrix. |
| Flash Point | Not applicable (solid propellant device) |
| Boiling Point | Not applicable (solid propellant device) |
| Vapor Density | Not applicable (solid device) |
| Water Reactivity | No significant reaction with water, though water cooling may be used on casings |
| Extinguishing | Water spray for cooling casings only; allow solid propellant to burn out; do not attempt to extinguish burning motors |
| PPE | ⚠️ Level B minimum with SCBA; structural firefighting gear with face shield; maintain distance due to fragment projection risk |
| Isolation | ERG 112: Initial isolation 500m in all directions; if fire or cargo involved evacuate 1600m radius; protect from heat and ignition sources |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Common hazards (high level)
- Fire and burning hazard — not mass explosion.
- Intense heat and possible fragment projection.
- May deflagrate and initiate other materials.
- Smoke and toxic combustion products.
First actions (field-minded)
- CALL 911. Then call emergency response telephone number on shipping paper.
- Isolate area; stage upwind — fire and fragment hazard.
- Request Hazmat + law enforcement.
- Control ignition sources; deny entry.
- Consult current ERG Guide 112 and follow SOP/SOG.
