  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.    NO open flames.    Use water spray, foam, alcohol-resistant foam, carbon dioxide.   

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Nausea.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Diarrhoea. Nausea. Vomiting.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: protective gloves and safety goggles. Collect leaking and spilled liquid in covered containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS VISCOUS LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic and corrosive fumes including acetic acid fumes, hydrogen sulfide and sulfur oxides. Reacts violently with strong acids and strong oxidants. This produces hydrogen sulfide.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
 

Effects of short-term exposure
The substance is mildly irritating to the eyes and respiratory tract. 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying. 

Effects of long-term or repeated exposure
 


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
 

NOTES
The boiling point is higher than the autoignition temperature.
