  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  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, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

 AVOID ALL CONTACT! PREVENT GENERATION OF MISTS!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat. Burning sensation.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED! Redness. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain.  Wear face shield or eye protection in combination with breathing protection.  Rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention. 
Ingestion Abdominal pain. Burning sensation in the throat and chest. Vomiting.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Refer 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. Do NOT let this chemical enter the environment. 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
No data. 

Chemical dangers
The substance may polymerize due to heating and under the influence of light, and peroxides. Decomposes on heating. This produces toxic and corrosive fumes including acrolein. Reacts violently with strong acids, strong bases, strong oxidants and peroxides. This generates fire hazard.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is severely irritating to the skin and eyes. The substance is irritating to the respiratory tract. If swallowed the substance may cause vomiting and could result in aspiration pneumonitis. 

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

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


OCCUPATIONAL EXPOSURE LIMITS
MAK sensitization of skin (SH) 

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

NOTES
Do NOT take working clothes home.
Skin cross-sensitization with other acrylates is possible.
A typical commercial sample of hydroxypropyl acrylate contains approximately 75-80% 2-hydroxypropyl acrylate and 20-25% 1-methyl-2- hydroxyethyl acrylate. The purity of the saleable product is at least 97% combined isomers.
See ICSC 0899.
An added stabilizer or inhibitor can influence the toxicological properties of this substance; consult an expert.
The effectiveness of phenolic inhibitors is dependent on the presence of oxygen. Store under air rather than inert atmosphere.
