Chemical & Response Details
| Also known as | Surface flaresMarine distress flaresRoad flaresSignal flaresPyrotechnic flares |
| Appearance | Cylindrical pyrotechnic devices containing combustible compositions, oxidizers, and binding agents. Typically red or orange colored casing. Solid at room temperature. |
| Flash Point | Not applicable (pyrotechnic device) |
| Boiling Point | Not applicable (pyrotechnic composition) |
| Vapor Density | Not applicable (solid pyrotechnic) |
| Water Reactivity | May contain water-reactive components; water generally not recommended for extinguishment |
| Extinguishing | Do not use water or foam; allow to burn out in controlled manner; sand or dry earth for small quantities |
| PPE | ⚠️ Level B minimum; structural firefighting gear with SCBA; face shield and heat-resistant clothing; maintain distance from burning flares |
| Isolation | ERG 112: isolate 500m in all directions; if fire or cargo fire, evacuate 1600m radius; allow flares to burn out if safe to do so |
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.
