TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Combustible.	NO open flames.	Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION	Above 74°C explosive vapour/air mixtures may be formed.	Above 74°C use a closed system, ventilation.	In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		AVOID ALL CONTACT!
Inhalation	Burning sensation. Cough. Headache. Nausea. Shortness of breath. Vomiting.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
Skin	Skin burns. Blisters.	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.	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 take to a doctor.
Ingestion	Burning sensation. Sore throat. (See Inhalation).	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. (Extra personal protection: complete protective clothing including self-contained breathing apparatus).	EU classification T+ Symbol R: 45-26-36/38 S: 53-45 Note: E UN classification UN Hazard Class: 6.1 UN Pack Group: I	Do not transport with food and feedstuffs.

EMERGENCY RESPONSE	SAFE STORAGE
NFPA Code: H0; F2; R0	Separated from food and feedstuffs. Cooled. Well closed. Ventilation along the floor.

IMPORTANT DATA
Physical State; Appearance COLOURLESS LIQUID, WITH PUNGENT ODOUR. Chemical dangers The substance may polymerize due to warming with fire or explosion hazard. Occupational exposure limits TLV: 0.5 ppm; 1.5 mg/m³ A3 (ACGIH 1997). MAK: skin absorption (H); Carcinogen category: 2 (DFG 2006).	Routes of exposure The substance can be absorbed into the body by inhalation and by ingestion. Effects of short-term exposure The substance is corrosive to the eyes and irritates, the skin and the respiratory tract. Effects of long-term or repeated exposure This substance is probably carcinogenic to humans.
