Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion on contact with heat or combustible substances.
NO contact with flammables.
In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water.
Cough. Shortness of breath.
Use local exhaust or breathing protection.
Fresh air, rest.
