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.  Use alcohol-resistant foam, carbon dioxide, water spray, powder. 
EXPLOSION      
 
EXPOSURE   STRICT HYGIENE!   
Inhalation See Ingestion.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED!  Protective gloves. Protective clothing.  Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Blue lips, fingernails and skin. Confusion. Convulsions. Cough. Dizziness. Headache. Laboured breathing. Nausea. Unconsciousness. Symptoms may be delayed. See Notes.  Do not eat, drink, or smoke during work.  Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING

IMPORTANT DATA
Physical State; Appearance
COLOURLESS-TO-WHITE CRYSTALS. TURNS DARK ON EXPOSURE TO AIR OR LIGHT. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic fumes of nitrogen oxides. Reacts violently with oxidants. This generates fire and explosion hazard. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

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

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization.
