	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Flammable. Above 28°C explosive vapour/air mixtures may be formed.	NO open flames, NO sparks and NO smoking. Above 28°C use a closed system, ventilation and explosion-proof electrical equipment.	Use water in large amounts, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Burning sensation. Cough. Laboured breathing. Nausea. Vomiting.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Half-upright position. Refer for medical attention.
Skin	Redness. Pain. Skin burns.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .
Eyes	Redness. Pain. Severe deep burns.	Wear face shield or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion	Dizziness. Abdominal cramps. Burning sensation. Vomiting. Abdominal pain. Shock or collapse. Nausea.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Refer for medical attention . Give one or two glasses of water to drink.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Evacuate danger area! Personal protection: self-contained breathing apparatus. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.	According to UN GHS Criteria Transportation UN Classification UN Hazard Class: 8; UN Subsidiary Risks: 3; UN Pack Group: II
STORAGE
Fireproof. Separated from acids, oxidants, aluminium, copper, zinc and food and feedstuffs. Well closed.
PACKAGING
Do not transport with food and feedstuffs.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS-TO-YELLOW LIQUID WITH PUNGENT ODOUR. Physical dangers Chemical dangers Decomposes on burning. This produces toxic and corrosive fumes including nitrogen oxides. The substance is a strong base. It reacts violently with acid and is corrosive. Reacts violently with strong oxidants. This generates fire hazard. Attacks aluminium, copper and zinc.
