UN 0012 — Cartridges for weapons, inert projectile
Placard: Explosive 1.4S. ERG Guide 114. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 0012 is Cartridges for weapons, inert projectile, a Class 1.4S ammunition or propellant-related entry assigned to ERG Guide 114. It presents a limited fire or deflagration hazard, but smoke, heat and fragments can still injure nearby personnel.
Hazard overview: UN 0012 presents a limited ammunition or propellant fire hazard. Heat or fire may cause localized deflagration, popping, fragments or smoke, especially if packages are damaged or quantities are larger than initially reported.
Response guidance: For a UN 0012 incident, responders should confirm the product using shipping papers, markings and ERG Guide 114. Isolate the area, keep personnel out of smoke, control ignition sources and expand the perimeter if fire involves additional ammunition or propellant.
Firefighter training notes: Training should emphasize the difference between limited-effect explosives and higher-hazard Class 1 materials. Common errors include standing too close to heated packages, dismissing smoke hazards, disturbing damaged articles and failing to check for adjacent explosives or ammunition.
Regulatory context: Cartridges for weapons, inert projectile is regulated as a Class 1 explosive hazardous material. Transportation, storage, quantity limits, fire code controls and reporting requirements may vary by jurisdiction. Responders should verify current requirements through shipping papers, SDS or product documents and applicable DOT, ATF, OSHA, NFPA, military, state or local authority guidance.
Storage & handling: Cartridges for weapons, inert projectile should be stored only in approved packaging, magazines or authorized explosive storage areas, separated from ignition sources, incompatible materials and unauthorized access. Packages should be protected from heat, impact, friction, moisture where relevant and physical damage according to product documentation and applicable explosive storage regulations.
