Hazards and Protection.
Storage
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Do not use water. Cover all suspected material with dry sand or earth to prevent ignition until material can be permanently disposed of. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Water spill: Use natural barriers or oil spill control booms to limit spill travel. Use natural deep water pockets, excavated lagoons, or sand bag barriers to trap material at bottom.
Stability
No data.
Incompatibilities
Reacts with acids to generate hydrogen sulfide, a toxic gas Reacts slowly with water and is decomposed by steam, generating hydrogen sulfide.

Fire.
Fire fighting
Do not use water. Use graphite, soda ash, powdered sodium chloride, or suitable dry powder. If fire is massive, back off, protect surroundings, and let burn. Keep run-off water out of sewers and water sources.
Fire potential
Flammable/combustible material.
Hazards
May ignite on contact with moist air or moisture. May burn rapidly with flare-burning effect. Some react vigorously or explosively on contact with water. Some may decompose explosively when heated or involved in a fire. May re-ignite after fire is extinguished. Runoff may create fire or explosion hazard.
Combustion products
Fire will produce irritating, corrosive and/or toxic gases.
