Chemical & Response Details
| Also known as | Rocket motors with expelling chargePyrotechnic rocketsSignal rocketsIlluminating rockets |
| Appearance | Assembled cylindrical devices containing propellant and expelling charge mechanisms. Typically constructed of metal, plastic, or composite materials with solid propellant grains and pyrotechnic payloads. |
| Flash Point | Not applicable (explosive device) |
| Boiling Point | Not applicable (explosive device) |
| Vapor Density | Not applicable (solid device) |
| Water Reactivity | May react with water depending on propellant composition; water may cause degradation of explosive components |
| Extinguishing | Do not use water or foam; fight fire from maximum distance with dry chemical or CO2 if small fire; evacuate area for large fire |
| PPE | ⚠️ Level B minimum with full face SCBA; explosive ordnance disposal protective ensemble recommended; maintain safe distance due to fragmentation hazard |
| Isolation | ERG 112: isolate 500m in all directions; evacuate 1600m in all directions if fire involved; treat as mass explosion hazard |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Common hazards (high level)
- Projection and fragmentation hazard on initiation.
- Blast overpressure in immediate area.
- Sensitive to heat, shock, or electrical current.
- May initiate other explosives in proximity.
First actions (field-minded)
- CALL 911. Then call emergency response telephone number on shipping paper.
- Isolate minimum 500 meters; stage upwind and uphill.
- Request Hazmat + law enforcement immediately.
- Control ignition sources; deny unauthorized entry.
- Do not approach — projectile/fragmentation hazard.
- Consult current ERG Guide 112 and follow SOP/SOG.
