Hydrogen chloride, nitrogen oxides, carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, nitrogen.
Fire-fighters should wear full protective clothing including self-contained breathing apparatus. In case of fire use water spray or fog type extinguishers (large quantities are required).
May explode from heat or contamination. May react explosively with hydrocarbons (fuels). May ignite combustibles.
May form toxic chlorine and other gases in fire.
Swallowing can result in diarrhoea, abdominal pain, ulceration of the stomach, lachrymation, difficulty in breathing, loss of consciousness, coma & possible death.
Inhalation of the dust will result in respiratory irritation. Decomposes when wet to evolve chlorine gas. Inhalation of chlorine will result in severe respiratory irritation. Delayed effects can include shortness of breath, severe headache, pulmonary oedema and pneumonia.
Contact with the skin will result in mild irritation. Repeated or prolonged skin contact may lead to allergic contact dermatitis.
A severe eye irritant. Contamination of the eyes can result in permanent injury. Corrosive to eyes; contact can cause corneal burns.
