March 2009
CAS #: 29590-42-9
UN #: 3082
EC Number: 249-707-8

  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Above 91°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 91°C use a closed system and ventilation.  Use water spray, dry powder, alcohol-resistant foam, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

 AVOID ALL CONTACT!  
  SYMPTOMS PREVENTION FIRST AID
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 CLASSIFICATION & LABELLING

PHYSICAL & CHEMICAL INFORMATION

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).

EXPOSURE & HEALTH EFFECTS

Routes of exposure
 

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. 

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


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
The substance is very toxic to aquatic organisms. It is strongly advised not to let the chemical enter into the environment. 

NOTES
May cause cross sensitization towards other acrylates.
Do NOT take working clothes home.
Refer for medical attention if breathing difficulties and/or fever develop.
An added stabilizer or inhibitor can influence the toxicological properties of this substance; consult an expert.
Health effects of exposure to the substance have not been investigated adequately.
