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

NFPA Code: H1; F3; R0. 
Fireproof. Separated from strong oxidants. Cool. Well closed. Keep in a well-ventilated room. 

IMPORTANT DATA
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. 

Occupational exposure limits
TLV: 200 ppm as TWA; 400 ppm as STEL; A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2005); notice of intended change (see Notes). 

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

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 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. 

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