UN 0284 — Grenades, hand or rifle, with bursting charge

Placard: Explosive 1.1F. ERG Guide 112. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.

🚒☣️
⚠️ 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 0284 covers hand and rifle grenades containing high explosive bursting charges designed to produce lethal blast overpressure and fragmentation upon detonation. These military munitions are classified as Division 1.1F explosives, meaning the entire shipment load is capable of mass detonation simultaneously.

Hazard overview: UN 0284 grenades present a dual-kill mechanism: severe blast overpressure capable of causing fatal injuries at distance, combined with high-velocity metal fragmentation projected outward from the explosive core. The devices are sensitive to heat, shock, and friction, making accidental initiation a serious risk during fire, collision, or improper handling.

Response guidance: Emergency responders must not attempt firefighting if UN 0284 grenades are directly exposed to flames — immediate withdrawal and full evacuation to 1600 meters (1 mile) is the required action. Isolation of 500 meters (1600 ft) in all directions must be established immediately, and all decisions should defer to explosive ordnance disposal (EOD) personnel.

Fireground Response Guidance — UN 0284

Extinguishing Media

DO NOT fight fire — withdraw immediately if grenades exposed to fire; use unmanned hose holders or monitor nozzles from maximum distance if fighting peripheral fires

PPE Requirements

⚠️ Evacuation only — no firefighting recommended; if absolutely necessary, full structural firefighting gear with SCBA from maximum distance behind blast-resistant barriers

Evacuation is the only recommended protective action — if peripheral fire suppression is absolutely unavoidable, full structural firefighting gear with SCBA must be worn from maximum distance behind blast-resistant barriers.

Isolation & Evacuation

ERG 112: Isolate 500m (1600 ft) all directions; if fire or explosion involved, evacuate 1600m (1 mile) radius; treat as mass explosion hazard (1.1)
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 112).

First Actions for a UN 0284 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 0284

Yes, UN 0284 is classified Division 1.1F, meaning the entire load can detonate simultaneously, producing a single catastrophic mass explosion event.

Full structural firefighting gear with SCBA is the minimum if evacuation is somehow not possible, but complete withdrawal is strongly preferred over any direct intervention.

No — while UN 0284 grenades do not react dangerously with water, immersion does not render them inert or safe for handling.
