  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Above 90°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 90°C use a closed system and ventilation.  Use water spray, powder, alcohol-resistant foam, carbon dioxide.   

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation Burning sensation. Confusion. Dizziness. Drowsiness. Laboured breathing. Sore throat.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Dry skin.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Burning sensation. Convulsions. Diarrhoea. Drowsiness. Vomiting.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Rest. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Ventilation. Cover the spilled material with earth or sand. Collect leaking and spilled liquid in covered containers as far as possible. Wash away remainder with plenty of water. 

According to UN GHS Criteria

 

Transportation
UN Classification
 

STORAGE

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on burning. This produces irritating fumes. Reacts with strong oxidants. This generates fire and explosion hazard.

EXPOSURE & HEALTH EFFECTS

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

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

Inhalation risk
A harmful contamination of the air will be reached rather 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. The substance may have effects on the kidneys. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 10 ppm as TWA; A4 (not classifiable as a human carcinogen)
