See Department of Transportation Emergency Response Guidebook GUIDE 153 and guidance for UN2810 VX (Table 1: Initial Isolation and Protective Action Distances).
Allow fire to continue to burn unless these actions would result in greater risk to the public.
Use protocols established for organophosphorus pesticides.
Use dry chemicals, carbon dioxide, alcohol-resistant foam or other foam materials to extinguish fires.
Fight fire from upwind and uphill, if at all possible.
Avoid using water to extinguish fires. FGAs are highly soluble in water, will persist, are highly mobile, and could contaminate larger areas.
Dike fire control water for later treatment and disposal; runoff from fire control or dilution water may be extremely toxic resulting in contaminated water supplies and further complicate clean-up efforts.
Smoke/steam plume may be contaminated by the agent; large areas downwind of fire may be affected by contaminated smoke/steam plume.
