  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Highly flammable.  Vapour/air mixtures are explosive. Heating will cause rise in pressure with risk of bursting.  NO open flames, NO sparks and NO smoking.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Use non-sparking handtools. 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 Sore throat. Cough. 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.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. Seek medical attention if you feel unwell. 

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. 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
Reacts with strong oxidants. This generates fire and explosion hazard. Reacts violently with strong bases and strong acids. 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 substance is mildly irritating to the eyes and respiratory tract. 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 will be reached rather slowly 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: 400 ppm as TWA.
MAK: 750 mg/m3, 200 ppm; peak limitation category: I(2); pregnancy risk group: C.
EU-OEL: 734 mg/m3, 200 ppm as TWA; 1468 mg/m3, 400 ppm as STEL
