  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Flammable. Gives off irritating or toxic fumes (or gases) in a fire.  Above 35°C explosive vapour/air mixtures may be formed.  NO open flames, NO sparks and NO smoking.  Above 35°C use a closed system, ventilation and explosion-proof electrical equipment.  Use water spray, powder, alcohol-resistant foam, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

 STRICT HYGIENE!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Sore throat. Cough. Burning sensation. Shortness of breath.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer for medical attention. 
Skin MAY BE ABSORBED! Redness. Pain. Blisters. See Notes.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Watering of the eyes. Pain. Burns.  Wear face shield or eye protection in combination with breathing protection.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention. 
Ingestion Burning sensation in the throat and chest.  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 CLASSIFICATION & LABELLING
Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Ventilation. Collect leaking liquid in covered containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS LIQUID WITH PUNGENT ODOUR. TURNS DARK ON EXPOSURE TO LIGHT. 

Physical dangers
 

Chemical dangers
The substance slowly polymerizes under the influence of light. This generates fire or explosion hazard. Decomposes on heating and on burning.

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
Lachrymation. The substance is severely irritating to the eyes, skin and respiratory tract. 

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

Effects of long-term or repeated exposure
 


Occupational exposure limits
TLV: 1 ppm as STEL; (skin) 

ENVIRONMENT
 

NOTES
After contact with liquid blister formation may be delayed until several hours have passed.
Explosive limits are unknown in literature, although the substance is combustible and has a flash point < 61°C.
The occupational exposure limit value should not be exceeded during any part of the working exposure.
The odour warning when the exposure limit value is exceeded is insufficient.
An added stabilizer or inhibitor can influence the toxicological properties of this substance; consult an expert.
