	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Flammable. Above 54°C explosive vapour/air mixtures may be formed. Risk of fire and explosion on contact with strong bases, strong oxidants or metals. See Chemical Dangers.	NO open flames, NO sparks and NO smoking. NO contact with strong bases, strong oxidizing agents or metals. See Chemical Dangers. Above 54°C use a closed system, ventilation and explosion-proof electrical equipment.	Use water spray, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

AVOID ALL CONTACT!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat. Burning sensation. Shortness of breath.	Use ventilation and local exhaust.	Fresh air, rest. Half-upright position. Refer immediately for medical attention.
Skin	Redness. Pain. Skin burns. Blisters.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer immediately for medical attention .
Eyes	Redness. Pain. Blurred vision. Severe burns.	Wear face shield.	Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.
Ingestion	Burning sensation. Sore throat. Abdominal pain. Vomiting. Shock or collapse.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Give nothing to drink. Refer immediately for medical attention.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance OILY COLOURLESS LIQUID WITH PUNGENT ODOUR. Physical dangers Chemical dangers The substance is a medium strong acid. Reacts with strong bases and strong oxidants. This generates fire and explosion hazard. This produces irritating or toxic fumes (or gases). Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001).
