  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Highly flammable.  Vapour/air mixtures are explosive.  NO open flames, NO sparks and NO smoking.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.  Use alcohol-resistant foam, foam, powder, carbon dioxide, fine water spray.  In case of fire: keep drums, etc., cool by spraying with water. 

 PREVENT GENERATION OF MISTS!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough. Sore throat. Headache. Drowsiness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness. Dry skin.  Protective gloves.  Rinse contaminated clothes (fire hazard) with plenty of water. Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness.  Wear safety spectacles or eye protection in combination with breathing protection.  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. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Do NOT wash away into sewer. Do NOT let this chemical enter the environment. Collect leaking liquid in sealable 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 WITH CHARACTERISTIC ODOUR. 

Physical dangers
The vapour mixes well with air, explosive mixtures are easily formed. 

Chemical dangers
Reacts with strong oxidants. This generates fire and explosion hazard. Reacts violently with strong acids and strong bases. Attacks rubber and some forms of plastic.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The vapour is mildly irritating to the eyes, respiratory tract and skin. The substance may cause effects on the central nervous system. Exposure far above the OEL could cause lowering of consciousness. 

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

Effects of long-term or repeated exposure
The substance defats the skin, which may cause dryness or cracking. 


Occupational exposure limits
TLV: 200 ppm as TWA; 250 ppm as STEL.
MAK: 420 mg/m3, 100 ppm; peak limitation category: I(2); pregnancy risk group: D 

ENVIRONMENT
The substance is harmful to aquatic organisms. 

NOTES
Do NOT take working clothes home.
