TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Flammable.  NO open flames, NO sparks and NO smoking.  Use water spray, powder, alcohol-resistant foam, carbon dioxide. 
EXPLOSION Above 33°C explosive vapour/air mixtures may be formed.  Above 33°C use a closed system, ventilation and explosion-proof electrical equipment.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   STRICT HYGIENE!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Cough. Sore throat.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED! Redness.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . Wear protective gloves when administering first aid. 
Eyes Pain. Severe deep burns.  Wear safety goggles, 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   Do not eat, drink, or smoke during work.  Rinse mouth. Rest. Refer for medical attention . 

SPILLAGE DISPOSAL

IMPORTANT DATA
Physical State; Appearance
COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
The vapour is heavier than air. 

Chemical dangers
The substance may polymerize under the influence of heat, oxidizers, peroxides and light. Reacts violently with oxidants. Attacks many plastics. 

Occupational exposure limits
TLV: 1ppm as TWA; (skin); (ACGIH 2004).
MAK: 2 ppm, 4.7 mg/m³; Peak limitation category: I(2); Pregnancy risk group: D; Skin absorption (H); (DFG 2006). 

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. 

Inhalation risk
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. The vapour is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the liver and kidneys. This may result in impaired functions. Exposure above the OEL could cause death. Medical observation is indicated. 

Effects of long-term or repeated exposure
