Fire may produce irritating and/or toxic gases.
Runoff from fire control or dilution water may cause environmental contamination.

Fire or explosion

Some of these materials may burn, but none ignite readily.
Most vapors are heavier than air.
Air/vapor mixtures may explode when ignited.

Public Safety

General

CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.
Keep unauthorized personnel away.
Stay upwind, uphill and/or upstream.
Many gases are heavier than air and will spread along the ground and collect in low or confined areas (sewers, basements, tanks, etc.).
Ventilate closed spaces before entering, but only if properly trained and equipped.

Protective clothing

Wear positive pressure self-contained breathing apparatus (SCBA).
Wear chemical protective clothing that is specifically recommended by the manufacturer when there is NO RISK OF FIRE.
Structural firefighters' protective clothing provides thermal protection but only limited chemical protection.

Evacuation

Immediate precautionary measure
Isolate spill or leak area for at least 50 meters (150 feet) in all directions.
Large Spill
Consider initial downwind evacuation for at least 100 meters (330 feet).
Fire
If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions.
