Remove contaminated clothing. Wash thoroughly with soap and water. Seek medical attention.
Open eyelids and flush with running water for 15 minutes. Seek medical attention.
Move to fresh air. If breathing stops, perform artificial respiration. Give oxygen. Seek medical attention.
Drink warm water, induce vomiting. Seek medical attention.
Combustible when exposed to open flame or high heat. Decomposes under high heat, releasing toxic fumes.
Carbon monoxide, carbon dioxide, nitrogen oxides, hydrogen chloride.
Water spray, foam, carbon dioxide, dry sand.
Firefighters must wear gas masks and full fire-fighting suits. Do not use direct water stream.
99 C
Isolate the contaminated area. Set up warning signs. Emergency responders should wear gas masks and general fire-fighting clothing. Do not contact spillage directly. Absorb with sand, vermiculite or other inert material. Collect and transport to waste disposal site. For large spills, collect for recycling or disposal after treatment.
Handle in enclosed systems with local exhaust ventilation. Operators must be specially trained. Wear self-priming filter respirator (half-mask), chemical safety goggles, chemical-resistant clothing and rubber gloves. Keep away from fire and heat sources. No smoking in work area. Use explosion-proof ventilation systems. Avoid contact with oxidizers, acids, acid anhydrides and acid chlorides.
Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. Keep container sealed. Store separately from oxidizers, acids, acid anhydrides and acid chlorides.
Enclosed production processes with general ventilation.
Wear gas mask when air concentration is high.
Chemical safety goggles.
Close-fitting work clothes and rubber boots.
Protective gloves.
