Fire Fighting MeasuresBack to Contents
【Flash Point】

>110
【Fire Fighting】

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Water Reactive. Material will react with water and may release a flammable and/or toxic gas. Contact with moisture or water may generate sufficient heat to ignite nearby combustible materials. Contact with acid or acid fumes evolves heat and flammable vapors. May re-ignite after fire is extinguished. May be ignited by heat, sparks, and flame. Extinguishing media: DO NOT USE WATER OR FOAM. For small fires use dry chemical, soda ash, lime or sand. For large fires use dry sand, dry chemical, soda ash or lime or withdraw from area and let fire burn. Contact with water or steam may produce toxic and flammable vapors.
Accidental Release MeasuresBack to Contents
【Small spills/leaks】

Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, using the appropriate protective equipment. Provide ventilation. Do not get water on spilled substances or inside containers. Cover with dry earth, dry sand, or other non-combustible material followed with plastic sheet to minimize spreading and contact with water. DO NOT CLEAN-UP OR DISPOSE OF, EXCEPT UNDER SUPERVISION OF A SPECIALIST.
