UN 0382 — Components, explosive train, n.o.s.
Placard: Explosive 1.1B. ERG Guide 112. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 0382 encompasses a range of Class 1.1B explosive train components—including detonators, boosters, primers, and igniter assemblies—housed in metallic or plastic bodies containing sensitive explosive compositions. The 1.1B classification signals the most severe explosive risk category, with the potential for instantaneous mass detonation of the entire load.
Hazard overview: A mass explosion involving UN 0382 can detonate the complete shipment simultaneously, generating catastrophic blast overpressure and high-velocity fragmentation across a wide radius. The sensitive nature of the individual components means that heat, shock, or friction can trigger cascading initiation through the explosive train.
Response guidance: Immediately isolate 500 meters in all directions and evacuate a 1,600-meter radius if any cargo is exposed to fire or heat; no personnel should approach without bomb squad or EOD authorization. Do not apply water, foam, or any suppression agent—evacuate the area and use distance and protective barriers as the sole protective measures.

PPE Requirements
No responder should approach without EOD clearance; if entry is absolutely required, minimum Level B with blast-resistant protection from the maximum achievable safe distance is the floor—not the standard.
Isolation & Evacuation
First Actions for a UN 0382 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.
