TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Flammable.  NO open flames, NO sparks and NO smoking.  Use water spray, powder, alcohol-resistant foam, carbon dioxide. 
EXPLOSION Above 41°C explosive vapour/air mixtures may be formed.  Above 41°C use a closed system, ventilation and explosion-proof electrical equipment.   
 
EXPOSURE   PREVENT GENERATION OF MISTS!   
Inhalation Cough. Sore throat. Unconciousness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. 
Skin Dry skin. Redness. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain.  Wear safety goggles.  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. Rest. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Ventilation. Collect leaking liquid in sealable containers. Absorb remaining liquid in 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. 

Physical dangers
The vapour is heavier than air and may travel along the ground; distant ignition possible. 

Chemical dangers
Reacts with strong oxidants. 

Occupational exposure limits
TLV: 25 ppm as TWA; 40 ppm as STEL; (skin); (ACGIH 2004).
MAK: 20 ppm, 85 mg/m³; Peak limitation category: I(1); Pregnancy risk group: D; (DFG 2006). 

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

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. Exposure could cause lowering of consciousness. 

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