Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
Small spills/leaks
Do not use water. Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Keep material dry.
Stability
No data.
Incompatibilities
Sensitive to shock, friction and heat Can react with metal powders (Cu, Ag) to form very sensitive detonators.

Fire.
Fire fighting
Do not use water. Use graphite, soda ash, powdered sodium chloride, or suitable dry powder.
Hazards
Produce flammable gases on contact with water. May ignite on contact with water or moist air. Some react vigorously or explosively on contact with water. May be ignited by heat, sparks or flames. May re-ignite after fire is extinguished. Some are transported in highly flammable liquids. Runoff may create fire or explosion hazard.
