Exposure Controls/Personal Protection

Personal Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).

Fire Fighting Measures

Fire Fighting
Small Fires: Dry chemical, carbon dioxide, water spray or regular foam. Large Fires: Flood fire area with water from a distance.
Fire Potential
Self-decomposition or self-ignition may be triggered by heat, chemical reaction, friction or impact.

Accidental Release Measures

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.
