TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames.  Use water spray, dry powder, alcohol-resistant foam, carbon dioxide. 
EXPLOSION Above 91°C explosive vapour/air mixtures may be formed.  Above 91°C use a closed system and ventilation.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   AVOID ALL CONTACT!   
Inhalation Cough.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin Redness.  Protective clothing. Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety spectacles.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion Vomiting. Aspiration hazard!  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. Seek medical attention if you feel unwell. See Notes. 

SPILLAGE DISPOSAL

IMPORTANT DATA
Physical State; Appearance
COLOURLESS LIQUID. 

Physical dangers
No data. 

Chemical dangers
The substance may polymerize due to heating. Decomposes on heating. This produces acrid fumes (acrylic acid, acrolein). 

Occupational exposure limits
TLV not established.
MAK (not established):. 

Routes of exposure
 

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. If swallowed the substance easily enters the airways and could result in aspiration pneumonitis. 

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