UN 0110 — Grenades, practice
Placard: Explosive 1.4G. ERG Guide 114. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 0110 refers to practice grenades, which are training devices containing a small explosive charge designed only to simulate the effects of a live grenade. These metal or composite shell devices present a limited but real explosive hazard and must be handled according to ERG Guide 114 protocols.
Hazard overview: UN 0110 practice grenades carry a minor blast and fire hazard, with potential for localized deflagration, smoke, and heat if the devices are damaged or exposed to flame. Fragmentation risk is low but cannot be ruled out, particularly if multiple devices are involved or subjected to sustained heat.
Response guidance: Responders should isolate the area to a minimum of 100 meters in all directions for any incident involving UN 0110 practice grenades. If fire or fragmentation hazard is present, the evacuation radius must be expanded to 250 meters in all directions per ERG Guide 114.
