Small spills/leaks	Clean up spills immediately, using the appropriate protective equipment. Sweep up, then place into a suitable container for disposal. Avoid generating dusty conditions.
Stability	Stable under normal temperatures and pressures.
Incompatibilities	Metals, strong oxidizing agents, strong bases, alkalies.
Decomposition	Phosgene, carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, chloride fumes.

Fire.
Flash Point,°C		61
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. To extinguish fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
Fire potential		Nonflammable.
Combustion products		Irritating hydrogen chloride vapor may form in fire.

First aid
Ingestion	Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Inhalation	Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Skin	Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
