UN 0314 — Igniters
Placard: Explosive 1.1G. ERG Guide 112. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 0314 covers Igniters — small pyrotechnic devices classified as Explosives 1.1G, used to initiate propellant or explosive charges via electrical or mechanical activation. A single incident involving UN 0314 can result in simultaneous detonation of the entire load, posing catastrophic risk to personnel and infrastructure.
Hazard overview: UN 0314 Igniters present a mass explosion hazard in which the complete cargo quantity may detonate as a single event, generating severe blast overpressure and high-velocity fragmentation. These devices are acutely sensitive to heat, shock, and friction, making any physical disturbance during an incident potentially initiating.
Response guidance: Emergency responders must immediately isolate the area 500 meters in all directions and evacuate at least 800 meters if fire or a major spill is present, per ERG Guide 112. If UN 0314 Igniters are directly involved in fire, personnel must withdraw immediately — fighting the fire is not an option and the fire should be allowed to burn out under controlled evacuation conditions.

PPE Requirements
Full structural firefighting gear with SCBA is mandatory but provides only limited protection against blast and fragmentation — immediate withdrawal is required if igniters are directly exposed to fire.
Isolation & Evacuation
First Actions for a UN 0314 Incident
- 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.
