  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Highly flammable.  Vapour/air mixtures are explosive.  NO open flames, NO sparks and NO smoking.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools.  Use water spray, powder, alcohol-resistant foam, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

 AVOID ALL CONTACT!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
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 clothing. Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain. Blurred vision.  Wear safety spectacles 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 CLASSIFICATION & LABELLING
Evacuate danger area! Consult an expert! Personal protection: self-contained breathing apparatus. Remove all ignition sources. Do NOT let this chemical enter the environment. 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

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS LIQUID WITH PUNGENT ODOUR. 

Physical dangers
The vapour mixes well with air, explosive mixtures are easily formed. 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.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. 

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

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. Tumours have been detected in experimental animals but may not be relevant to humans. 


Occupational exposure limits
TLV: 5 ppm as TWA; 15 ppm as STEL; A4 (not classifiable as a human carcinogen).
MAK: 8.3 mg/m3, 2 ppm; peak limitation category: I(2); skin absorption (H); sensitization of skin (SH); pregnancy risk group: C.
EU-OEL: 21 mg/m3, 5 ppm as TWA; 42 mg/m3, 10 ppm as STEL 

ENVIRONMENT
The substance is toxic to aquatic organisms. 

NOTES
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
Do NOT take working clothes home.
