UN 0325 — Igniters
Placard: Explosive 1.4G. ERG Guide 114. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 0325 Igniters are small pyrotechnic devices—typically housed in metal or plastic casings—designed to initiate combustion in propellant or explosive systems. Classified as Explosive 1.4G, they present a localized fire and deflagration risk with limited blast potential under most conditions.
Hazard overview: If ignited, UN 0325 Igniters can undergo rapid deflagration, producing smoke, heat, and localized burning that may propagate to adjacent pyrotechnic material. The 1.4G classification indicates a minor blast hazard confined largely to the immediate package, though burning devices can scatter and ignite secondary fires.
Response guidance: Isolate the incident area a minimum of 100 meters in all directions; if cargo is involved in fire, expand isolation to 800 meters and evaluate evacuation of the same radius per ERG Guide 114. Apply water spray only from a safe standoff distance—avoid direct streams that could scatter burning devices—and consider dry chemical or CO2 as alternatives.
