UN 0092 — Flares, surface
Placard: Explosive 1.3G. ERG Guide 112. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 0092 covers surface flares, which are cylindrical pyrotechnic devices containing combustible materials and oxidizers designed to produce intense light and heat when ignited. These devices are classified as Class 1 explosives under placard Explosive 1.3G and are referenced under ERG Guide 112.
Hazard overview: UN 0092 surface flares present a serious fire and burning hazard with potential for intense heat output and fragment projection upon ignition or damage. These devices may deflagrate and initiate combustion in nearby materials, though they do not pose a mass explosion risk.
Response guidance: In an incident involving UN 0092, isolate the spill or leak area to a minimum of 500 meters in all directions and expand the evacuation radius to 800 meters if fire is involved. Do not use water or foam to extinguish burning flares; instead, apply dry sand or earth to cover them and allow them to burn out in a controlled manner.

PPE Requirements
Responders handling UN 0092 surface flares require a minimum of Level C protection with full face coverage, heat-resistant gloves, mandatory eye protection, and SCBA if smoke is present.
Isolation & Evacuation
First Actions for a UN 0092 Incident
- CALL 911. Then call emergency response telephone number on shipping paper.
- Isolate area; stage upwind — fire and fragment hazard.
- Request Hazmat + law enforcement.
- Control ignition sources; deny entry.
- Consult current ERG Guide 112 and follow SOP/SOG.
