Oxidizing agents.
Decomposition
Irritating and toxic fumes and gases, ammonia and/or derivatives.

Fire.
Fire fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Water Reactive. Material will react with water and may release a flammable and/or toxic gas. Flammable when exposed to flame. May ignite or explode on contact with steam or moist air. Extinguishing media: Do NOT use water directly on fire. DO NOT USE WATER! Contact professional fire-fighters immediately. For large fires use dry sand, dry chemical, soda ash or lime or withdraw from area and let fire burn. For small fires, use dry chemical, soda ash, lime or dry sand.
Hazards
Produce flammable and toxic 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.
Combustion products
Fire will produce irritating, corrosive and/or toxic gases.
