  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Flammable.  Above 25°C explosive vapour/air mixtures may be formed.  NO open flames, NO sparks and NO smoking.  Above 25°C use a closed system, ventilation and explosion-proof electrical equipment.  Use alcohol-resistant foam, powder, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

   
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough. Dizziness. Drowsiness. Headache. Sore throat.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin Dry skin. Redness.  Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear face shield or eye protection in combination with breathing protection.  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. Give one or two glasses of water to drink. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Remove all ignition sources. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. 

According to UN GHS Criteria

 

Transportation

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
The vapour is heavier than air. 

Chemical dangers
Reacts with oxidants. This generates fire and explosion hazard. Attacks many plastics.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. Exposure at high levels could cause lowering of consciousness. 

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

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


Occupational exposure limits
TLV: 50 ppm as TWA; 100 ppm as STEL.
MAK: 270 mg/m3, 50 ppm; peak limitation category: I(1); pregnancy risk group: C.
EU-OEL: 270 mg/m3, 50 ppm as TWA; 540 mg/m3, 100 ppm as STEL 

ENVIRONMENT
 

NOTES
Use of alcoholic beverages enhances the harmful effect.
