UN 0106 — Fuzes, detonating
Placard: Explosive 1.1B. ERG Guide 112. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 0106 identifies detonating fuzes, which are metallic or plastic cylindrical devices containing primary and secondary explosive charges designed to initiate main explosive charges. These compact initiating devices fall under Explosive Class 1.1B, indicating a mass explosion hazard capable of simultaneous detonation of the entire load.
Hazard overview: UN 0106 presents a mass explosion hazard in which the entire load may detonate simultaneously, producing severe blast overpressure and dangerous fragmentation. These devices are highly sensitive to heat, shock, and friction, making any disturbance during an incident extremely dangerous.
Response guidance: Upon encountering UN 0106, immediately isolate the area a minimum of 500 meters in all directions and restrict access to trained EOD personnel only. If fire is involved, evacuate all persons at least 1600 meters in all directions and do not attempt extinguishment under any circumstances.

PPE Requirements
Approach to UN 0106 must never be made by untrained personnel; only EOD-qualified responders wearing full protective equipment should attempt any engagement after full area evacuation.
Isolation & Evacuation
First Actions for a UN 0106 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.
