Fireground Response Guidance — UN 2009
Extinguishing Media
Dry sand, dry chemical, soda ash; DO NOT use water, foam, CO2, or halogenated agents
PPE Requirements
⚠️ Level B minimum with SCBA; fire-resistant clothing; face shield; avoid skin contact with metal dust or heated surfaces
Isolation & Evacuation
ERG 135: isolate spill/leak area 25m in all directions; if fire involved, isolate 800m and consider evacuation 800m downwind
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 135).
First Actions for a UN 2009 Incident
- CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper
- Stay upwind, uphill and/or upstream.
- Keep unauthorized personnel away.
- Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters
- For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.
- For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind
