  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Flammable. Heating will cause rise in pressure with risk of bursting.  Above 60°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 60°C use a closed system, ventilation and explosion-proof electrical equipment.  Use water spray, foam, powder, carbon dioxide.  In case of fire: keep cylinder cool by spraying with water. 

 PREVENT GENERATION OF MISTS!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Dizziness. Drowsiness. Lethargy. Headache. Sore throat.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. 
Skin Dry skin. Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Redness.  Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Nausea. 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: self-contained breathing apparatus. Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. 

According to UN GHS Criteria

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
The vapour is heavier than air and may travel along the ground; distant ignition possible. 

Chemical dangers
The substance may polymerize due to warming. This generates fire or explosion hazard. Reacts with strong oxidants and strong acids. 

Formula: CH3C6H4CH=CH2 / C9H10
Molecular mass: 118.2
Boiling point: 172°C
Relative density (water = 1): 0.91
Relative vapour density (air = 1): 4.1
Flash point: 60°C
Explosive limits, vol% in air: 1.9-6.1
Octanol/water partition coefficient as log Pow: 3.580  


EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the central nervous system. 

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. The substance defats the skin, which may cause dryness or cracking. The substance may have effects on the liver and kidneys. This may result in tissue lesions. 


OCCUPATIONAL EXPOSURE LIMITS
MAK: 98 mg/m3, 20 ppm; peak limitation category: I(2); pregnancy risk group: D.
