  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Above 71°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 71°C use a closed system and ventilation.  Use water spray, powder, alcohol-resistant foam, carbon dioxide.   

 PREVENT GENERATION OF MISTS!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Headache. Dizziness. Drowsiness. Nausea.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED! Redness. Dry skin.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Burning sensation in the throat and chest. Vomiting. Further see Inhalation.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The vapour is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the central nervous system. Exposure far above the OEL could cause unconsciousness. The substance may cause effects on the blood. This may result in lesions of blood cells and kidney impairment. 

Inhalation risk
 

Effects of long-term or repeated exposure
The substance defats the skin, which may cause dryness or cracking. The substance may have effects on the blood. This may result in anaemia and kidney impairment. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 20 ppm as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans).
MAK: 66 mg/m3, 10 ppm; peak limitation category: I(2); skin absorption (H); carcinogen category: 4; pregnancy risk group: C.
EU-OEL: 133 mg/m3, 20 ppm as TWA; 333 mg/m3, 50 ppm as STEL; (skin) 

ENVIRONMENT
The substance is harmful to aquatic organisms. 

NOTES
Check for peroxides prior to distillation; eliminate if found.
