  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire.  Vapour/air mixtures are explosive.  NO open flames, NO sparks and NO smoking. NO contact with oxidizing agents.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.  Use water spray, powder, alcohol-resistant foam, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

   
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Incoordination. Confusion. Dizziness. Drowsiness. Headache. Nausea. Weakness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin Dry skin.  Protective gloves.  Rinse and then wash skin with water and soap. 
Eyes Redness. Pain. Blurred vision.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Sore throat. Vomiting. See Inhalation.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Ventilation. 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
UN Classification
UN Hazard Class: 3; UN Pack Group: II

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
CLEAR COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
The vapour mixes well with air, explosive mixtures are easily formed. 

Chemical dangers
Reacts with strong oxidants. This generates fire and explosion hazard. Attacks some forms of plastic and rubber.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the eyes. The substance may cause effects on the central nervous system. Exposure at high levels 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. 


Occupational exposure limits
TLV: 100 ppm as TWA; A4 (not classifiable as a human carcinogen) 

ENVIRONMENT
 

NOTES
Use of alcoholic beverages enhances the harmful effect.
