TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames. NO contact with oxidizing agents.  Use water spray, alcohol-resistant foam, dry powder, carbon dioxide. 
EXPLOSION Above 90°C explosive vapour/air mixtures may be formed.  Above 90°C use a closed system and ventilation.   
 
EXPOSURE      
Inhalation Cough. Sore throat. Nausea. Convulsions. Dizziness. Laboured breathing. Pupillary constriction, muscle cramp, excessive salivation. Sweating. Unconciousness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. 
Skin MAY BE ABSORBED! Skin burns. Pain. Redness. See Inhalation.  Protective clothing. Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Pain. Redness. Severe deep burns.  Wear face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Burning sensation. Shock or collapse. Abdominal cramps. Diarrhoea. Vomiting. See Inhalation.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention . 

SPILLAGE DISPOSAL

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

Physical dangers
 

Chemical dangers
Reacts with oxidants. Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001). Decomposes on burning. This produces nitrogen oxides. 

Occupational exposure limits
TLV: 0.5ppm as TWA; (skin); BEI issued; (ACGIH 2004). 

Routes of exposure
The substance can be absorbed into the body by inhalation, 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 corrosive to the eyes and skin. The vapour is irritating to the respiratory tract. Corrosive on ingestion. The substance may cause effects on the central nervous system. This may result in convulsions and respiratory failure. Cholinesterase inhibition. Exposure could cause death. Medical observation is indicated. The effects may be delayed. 

Effects of long-term or repeated exposure
