TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Flammable.  NO open flames, NO sparks and NO smoking. NO contact with strong oxidizing agents.  Use powder, AFFF, foam, carbon dioxide. 
EXPLOSION Above 36°C explosive vapour/air mixtures may be formed.  Above 36°C use a closed system, ventilation and explosion-proof electrical equipment. NO contact with strong oxidizing agents.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   PREVENT GENERATION OF MISTS! AVOID ALL CONTACT!   
Inhalation Burning sensation. 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. 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. Nausea. Vomiting. Diarrhoea.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: chemical protection suit and filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. 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.

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

Physical dangers
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 oxidants. This generates fire and explosion hazard. 

Occupational exposure limits
TLV: 2ppm as TWA; (SEN); A4 (not classifiable as a human carcinogen); (ACGIH 2002).
MAK: 2 ppm, 11 mg/m³; Peak limitation category: I(2); Pregnancy risk group: D; Sensitization of skin (SH); (DFG 2003). 

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

Inhalation risk
A harmful contamination of the air can be reached rather 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. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. 

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