Absorb spill using an absorbent, non-combustible material such as earth, sand, or vermiculite. Provide ventilation. Do not get water inside containers.
Stable under normal temperatures and pressures. May decompose on exposure to moist air or water.
Moisture, water, alcohols, amines, acids, heat, strong oxidizing agents, strong bases.
Hydrogen chloride, hydrogen cyanide, nitrogen oxides, carbon monoxide, oxides of sulfur, irritating and toxic fumes and gases, carbon dioxide.
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. Extinguishing media: Do NOT get water inside containers. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
Contact with metals may evolve flammable hydrogen gas.
Fire may produce irritating, corrosive and/or toxic gases.
May cause irritation of the digestive tract. The toxicological properties of this substance have not been fully investigated.
May cause respiratory tract irritation. The toxicological properties of this substance have not been fully investigated. May cause burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting.
May cause skin irritation.
May cause eye irritation. Lachrymator.
Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
