⚠️ Level B minimum; SCBA required in enclosed spaces; insulated gloves for contact with liquefied gas to prevent frostbite
Isolation & Evacuation
ERG 126: isolate spill or leak area immediately for at least 100m in all directions; if tank/rail car involved in fire isolate 800m in all directions
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 126).
First Actions for a UN 1009 Incident
- CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper
- Keep unauthorized personnel away.
