Fire Fighting Measures

Flash Point

-18

Fire Fighting

DO NOT USE WATER, carbon dioxide OR FOAM ON MATERIAL ITSELF. It may react violently with water. Smothering may not be effect.

Fire Potential

Flammable/combustible material. Spontaneously flammable in air.

Accidental Release Measures

Small spills/leaks

Use a fully encapsulating, vapor protective clothing should be worn for spills and leaks with no fire. ELIMINATE all ignition sources and prevent all contact with spilled material. Stop leak if you can do it without risk. Cover with DRY earth, DRY sand, or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain. Use clean non-sparking tools to collect material and place it into loosley covered plastic containers for later disposal. This is a generic DOT guideline. EXCEPTION: For Dithionite (Hydrosulfite/Hydrosulphite) spills, UN1384, UN1923 and UN1929, dissolve with 5 parts water and collect for proper disposal.
