TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames.  Use water spray, foam, alcohol-resistant foam, carbon dioxide. 
EXPLOSION      
 
EXPOSURE      
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
PACKAGING & 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.

IMPORTANT DATA
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. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
 

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

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

Effects of long-term or repeated exposure
