TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Highly flammable. Heating will cause rise in pressure with risk of bursting. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames, NO sparks and NO smoking.  Use water spray, alcohol-resistant foam, powder, carbon dioxide. 
EXPLOSION Vapour/air mixtures are explosive.  Closed system, ventilation, explosion-proof electrical equipment and lighting.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE      
Inhalation Headache. Nausea. Dizziness. Palpitations.  Use closed system or ventilation.  Fresh air, rest. 
Skin   Protective gloves.  Rinse and then wash skin with water and soap. 
Eyes   Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. Rest. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer.

IMPORTANT DATA
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
On combustion, forms sulfur oxides. Reacts with strong oxidants such as nitric acid. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK: 50 ppm, 180 mg/m³; Peak limitation category: I(1); Pregnancy risk group: D; (DFG 2005). 

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

Inhalation risk
 

Effects of short-term exposure
The substance may cause effects on the central nervous system. 

Effects of long-term or repeated exposure
