Hazards and Protection.
Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
ELIMINATE all ignition sources and combustible materials. Do not touch spilled material. Stop leak if you can do it without risk. Take up with inert, damp, noncombustible material using clean non-sparking tools and place into loosely covered plastic containers for later disposal. For large spills, contact specialist for clean-up or disposal instructions.

Fire.
Fire fighting
The temperature of the substance must be maintained at or below the Control Temperature at all times. Small Fires: Water spray or fog is preferred; if water not available use dry chemical, carbon dioxide or regular foam. Large Fires: Flood fire area with water from a distance. Use water spray or fog; do not use straight streams.
Fire potential
May explode from heat, contamination or loss of temperature control. Particularly sensitive to temperature rises.
Hazards
May ignite combustibles (wood, paper, oil, clothing, etc.). May ignite spontaneously if exposed to air. May be ignited by heat, sparks or flames.
Combustion products
Fire may produce irritating, corrosive and/or toxic gases.
