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, foam, powder, carbon dioxide. 
EXPLOSION Above 79°C explosive vapour/air mixtures may be formed.  Above 79°C use a closed system and ventilation.   
 
EXPOSURE   PREVENT GENERATION OF MISTS!   
Inhalation Blue lips, fingernails and skin. Convulsions. Dizziness. Laboured breathing. Vomiting. Symptoms may be delayed. See Notes.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness. MAY BE ABSORBED! Further see Inhalation.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
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 See Inhalation.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Give one or two glasses of water to drink. Give a slurry of activated charcoal in water to drink. Refer for medical attention . See Notes.

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic fumes including nitrogen oxides. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. 

Effects of short-term exposure
The substance is irritating to the skin and eyes. The substance may cause effects on the blood. This may result in formation of methaemoglobin. Medical observation is indicated. The effects may be delayed. 

Effects of long-term or repeated exposure
The substance may have effects on the blood. This may result in anaemia.
