EC Number: 212-782-2

  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Above 97°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 97°C use a closed system and ventilation.  Use water spray, dry powder, alcohol-resistant foam.  In case of fire: keep drums, etc., cool by spraying with water. 

 PREVENT GENERATION OF MISTS!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat.  Use ventilation (not if powder), local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness.  Protective gloves. Protective clothing.  First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention . 
Eyes Redness.  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 Sore throat. Aspiration hazard!  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer immediately for medical attention. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: chemical protection suit and filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. 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. 

Physical dangers
 

Chemical dangers
The substance will polymerize due to heating, on contact with peroxides, and under the influence of light. Heating may cause violent combustion or explosion. This produces acrid smoke. The substance may spontaneously polymerize if it is not stabilized.

See Notes.
Melting point: <-60°C
Density: 1.07 g/cm³
Solubility in water: miscible
Vapour pressure, Pa at 25°C: 17
Relative vapour density (air = 1): 4.5
Flash point: 97°C c.c.
Octanol/water partition coefficient as log Pow: 0.42

EXPOSURE & HEALTH EFFECTS

Routes of exposure
 

Effects of short-term exposure
The substance is substance irritating to the eyes, skin and respiratory tract. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. 

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

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


OCCUPATIONAL EXPOSURE LIMITS
MAK sensitization of skin (SH) 

ENVIRONMENT
 

NOTES
Boiling Point cannot be experimentally determined: at 1013 hPa polymerization occurs at elevated temperatures, other boiling point: 67 C at 4.6 hPa.
Methacrylates are normally stabilized by addition of phenolic inhibitors during transport and storage.
An added stabilizer or inhibitor can influence the toxicological properties of this substance; consult an expert.
May cause cross sensitization towards other acrylates.
