UN 0174 — Rivets, explosive
Placard: Explosive 1.4S. ERG Guide 114. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 0174 refers to explosive rivets, which are metallic fasteners containing small integral explosive charges used in industrial and aerospace applications. These devices are classified as Class 1 explosives with a 1.4S placard, indicating a minor blast or fire hazard with effects largely confined to the immediate package.
Hazard overview: UN 0174 explosive rivets present a localized blast and deflagration risk, with any detonation or burning typically limited in effect and unlikely to cause mass explosion. Smoke and heat generated from burning units may pose secondary hazards to responders in close proximity.
Response guidance: In the event of a UN 0174 incident, establish an isolation perimeter of at least 200 meters in all directions and expand to 800 meters with downwind evacuation if fire is involved. Apply dry chemical, sand, or water spray from a safe distance, and avoid directing high-pressure streams directly onto burning or damaged devices.
