Hazards and Protection.
Storage
Store in a cool, dry area in a tightly closed container. Keep away from sparks, heat and flame.
B6
Handling
Preferably, use in an inert atmosphere of nitrogen or argon. Use in work area where relative humidity is below 50%. Use only in work areas haveing adequate ventilation or use an approved respirator.
Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
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
Stable.
Incompatibilities
Incompatible with oxidizing agents such as atmospheric oxygen Incompatible with acids, particularly oxidizing acids Reacts violently with copper(I) chloride to produce metallic copper Reacts exothermically with silicon tetrafluoride, leading to explosion.
Decomposition
Reacts violently with water producing ammonia. and may be shock sensitive.

Fire.
Fire fighting
Do not use water. Do not use dry chemical or carbon dioxide. Use graphite, soda ash or powdered sodium chloride.
Fire potential
Produce flammable gases on contact with water.
Hazards
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.
Combustion products
Fire will produce irritating, corrosive and/or toxic gases.
