TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Flammable. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames, NO sparks and NO smoking. NO contact with hot surfaces.  Use water spray, alcohol-resistant foam. 
EXPLOSION Above 32°C explosive vapour/air mixtures may be formed.  Above 32°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. Sore throat.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Redness. Pain. Blurred vision.  Wear safety goggles 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
PACKAGING & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. 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.   
EC Classification
 
UN Classification
UN Hazard Class: 3; UN Pack Group: III 
GHS Classification
 

EMERGENCY RESPONSE SAFE STORAGE
NFPA Code: H2; F3; R0.  Fireproof. Separated from strong oxidants. 

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

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic gases and vapours (ammonia; nitrogen oxides; carbon monoxide). Reacts violently with strong oxidants. This generates fire and explosion hazard. Attacks plastics, rubber and coatings. 

Occupational exposure limits
TLV: 5ppm as TWA; (skin); (ACGIH 2002). 

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

Inhalation risk
A harmful contamination of the air can be reached rather quickly 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 eyes. This may result in distortion of vision. 

Effects of long-term or repeated exposure
