UN 0323 — Cartridges, power device
Placard: Explosive 1.4S. ERG Guide 114. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 0323 identifies Cartridges, power device — small propellant-loaded metallic cartridges used in industrial power tools and actuating devices, classified as Division 1.4S explosives. These articles pose a minor blast or fire hazard with limited effect, though localized deflagration and smoke generation are possible under fire conditions.
Hazard overview: UN 0323 cartridges may undergo localized burning or deflagration if exposed to fire, producing smoke and heat but typically limited blast overpressure due to their 1.4S classification. Mass detonation is not expected; however, bulk quantities in a fire scenario can produce multiple small-scale reactions in rapid succession.
Response guidance: Per ERG Guide 114, establish an isolation perimeter of 100 meters in all directions; if cartridges are involved in fire or explosion, evacuate a 500-meter radius. Suppress surrounding fires with water spray, dry chemical, or CO2, but avoid direct attack on burning cartridges — allow to burn out if safe to do so.
