⚠️ This page is a quick-reference aid. For real incidents: stage upwind, isolate, deny entry, request Hazmat early, and consult the current ERG + SOP/SOG.

UN 0360, Detonator assemblies non-electric for blasting, are Class 1.1B explosive devices consisting of cylindrical metal or plastic housings containing primary and secondary explosive charges connected by shock tube or detonating cord. Their 1.1B classification indicates a mass explosion hazard, meaning the entire quantity present could detonate simultaneously under fire or shock conditions.

Hazard overview: UN 0360 presents a severe mass explosion hazard capable of producing catastrophic blast overpressure waves and high-velocity fragmentation across a wide radius if the load is involved in fire or subjected to mechanical shock. Unlike fire-only hazards, a sympathetic detonation event with these assemblies offers responders virtually no intervention window.

Response guidance: Evacuation is the primary and preferred response for any incident involving UN 0360; per ERG Guide 112, immediately isolate 500 meters in all directions and evacuate 1600 meters if the cargo is on fire. Fire suppression must not be attempted — responders should use maximum distance and solid barriers for protection and deny all access to the hazard zone.

Fireground Response Guidance — UN 0360

Extinguishing Media

Do not use water or foam; use distance and protective barriers only; do not attempt fire suppression

PPE Requirements

⚠️ Evacuation is primary response; if approach required, Level B with blast-resistant cover, SCBA mandatory, approach from maximum distance behind barriers

Evacuation is the primary protective action; if approach is absolutely unavoidable, Level B protection with SCBA is mandatory, and responders must approach from maximum possible distance using blast-resistant cover as shielding.

Isolation & Evacuation

ERG 112: Initial isolation 500m in all directions; if fire or cargo involved, evacuate 1600m radius; treat as mass detonation hazard

Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 112).

First Actions for a UN 0360 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.

Frequently Asked Questions about UN 0360

Yes, UN 0360 detonator assemblies are classified 1.1B, indicating a mass explosion hazard. In a fire scenario, the entire quantity present can detonate simultaneously, producing severe blast overpressure and fragmentation with no safe suppression option for first responders.

ERG Guide 112 specifies an initial isolation of 500 meters in all directions for UN 0360 incidents. If the material is on fire or involved in an explosion, the evacuation radius expands to 1600 meters, and the area must be denied to all non-essential personnel.

UN 0360 detonators are engineered for transport safety when handled correctly per DOT and ADR regulations, but they remain Class 1.1B mass explosion hazards that require strict segregation, proper placarding, and immediate emergency protocols if an incident occurs.
