UN 0267 — Detonators, non-electric, for blasting
Placard: Explosive 1.4B. ERG Guide 114. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 0267 covers non-electric detonators for blasting, also known as non-electric blasting caps, shock tube detonators, and safety fuse detonators, which contain primary explosive charges in small metal or plastic cylindrical shells. These devices are classified as Explosive 1.4B, indicating a minor blast or fire hazard with effects largely confined to the immediate area.
Hazard overview: UN 0267 detonators present a risk of localized deflagration or burning, producing smoke and heat if ignited, with blast effects limited in scope due to the 1.4B classification. The primary danger escalates significantly if the devices are exposed to fire, as sympathetic detonation of nearby units is possible.
Response guidance: Responders should not attempt to fight a fire that has reached UN 0267 detonators; if fighting fire is feasible from a safe distance, flooding amounts of water may be applied. Isolate all directions to a minimum of 100 meters, expanding to 500 meters with an 800-meter evacuation zone if a large fire or any fire involves the explosives.

PPE Requirements
A minimum of Level B protection is required, as structural firefighter protective clothing provides only limited protection against the blast and fragmentation hazards of UN 0267 detonators.
Isolation & Evacuation
First Actions for a UN 0267 Incident
- CALL 911. Notify law enforcement.
- Isolate area; keep unauthorized personnel away.
- Stage upwind; eliminate ignition sources.
- Request Hazmat + law enforcement.
- Consult current ERG Guide 114 and follow SOP/SOG.
