TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Flammable.  NO open flames, NO sparks and NO smoking.  Use AFFF, alcohol-resistant foam, powder, carbon dioxide. 
EXPLOSION Above 48°C explosive vapour/air mixtures may be formed.  Above 48°C use a closed system, ventilation and explosion-proof electrical equipment.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE      
Inhalation Cough. Dizziness. Headache. Unconciousness. Blurred vision.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Dry skin. Redness.  Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
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   Do not eat, drink, or smoke during work.  Rinse mouth. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Ventilation. Collect leaking and spilled liquid in sealable metal containers as far as possible. Absorb remaining liquid in dry sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer.

IMPORTANT DATA
Physical State; Appearance
COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
Reacts with oxidizing materials. Attacks some forms of plastic. 

Occupational exposure limits
TLV: 50ppm as TWA; (ACGIH 2004). 

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

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

Effects of short-term exposure
The substance 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 lowering of consciousness. 

Effects of long-term or repeated exposure
The liquid defats the skin.
