  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Above 78°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 78°C use a closed system and ventilation.  Use water spray, powder, alcohol-resistant foam, carbon dioxide.   

   
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation   Use ventilation. Use local exhaust.  Fresh air, rest. 
Skin Dry skin.  Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  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. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Collect leaking liquid in sealable containers. Wash away remainder with plenty of water. 

According to UN GHS Criteria

EXPOSURE & HEALTH EFFECTS

Routes of exposure
 

Effects of short-term exposure
The substance is irritating to the eyes. 

Inhalation risk
A harmful contamination of the air will be reached slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. 

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


Occupational exposure limits
TLV: 10 ppm as TWA.
MAK: 67 mg/m3, 10 ppm; peak limitation category: I(1); pregnancy risk group: C.
EU-OEL: 67.5 mg/m3, 10 ppm as TWA; 101.2 mg/m3, 15 ppm as STEL 

ENVIRONMENT
 

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