TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Highly flammable.  NO open flames, NO sparks and NO smoking.  Use foam, powder, carbon dioxide. 
EXPLOSION Vapour/air mixtures are explosive.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   AVOID ALL CONTACT!   
Inhalation Cough. Cough. Shortness of breath. Sore throat.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Redness. Pain.  Wear safety goggles 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 Abdominal pain. Diarrhoea. Nausea. Vomiting.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Remove all ignition sources. Collect leaking and spilled liquid in covered containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT let this chemical enter the environment. Personal protection: chemical protection suit and filter respirator for organic gases and vapours adapted to the airborne concentration of the substance.  Unbreakable packaging.
Put breakable packaging into closed unbreakable container.

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

Physical dangers
The vapour is heavier than air and may travel along the ground; distant ignition possible. Vapours are uninhibited and may polymerize, causing blockage of vents. 

Chemical dangers
The substance may spontaneously polymerize due to warming, under the influence of light and on contact with peroxides. Reacts violently with strong acids, strong bases and strong oxidants. This generates fire and explosion hazard. 

Occupational exposure limits
TLV: 2ppm as TWA; (skin); (SEN); A4 (not classifiable as a human carcinogen); (ACGIH 2003).
MAK: 5 ppm, 18 mg/m³; Peak limitation category: I(1); Pregnancy risk group: D; Sensitization of skin (SH); (DFG 2006). 

Routes of exposure
The substance can be absorbed into the body by inhalation, 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 severely irritating to the eyes. The substance is irritating to the skin and respiratory tract. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization.
