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 strong oxidizing agents or sulfuric acid.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION Risk of fire and explosion on contact with strong oxidizing agents or sulfuric acid.    Combat fire from a sheltered position. 
 
EXPOSURE      
Inhalation Blue lips, fingernails and skin. Confusion. Convulsions. Dizziness. Headache. Nausea. Unconciousness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED! Redness. See Inhalation.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
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.  Rinse mouth. Refer for medical attention .

Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic gases including carbon monoxide and nitrogen oxides. Reacts with strong oxidants and sulfuric acid. This generates fire and explosion hazard. Attacks plastics, rubber and coatings. 

Occupational exposure limits
TLV: 2ppm as TWA; (skin); BEI issued; (ACGIH 2004).
MAK: 5 ppm, 28 mg/m³; Peak limitation category: II(2); Skin absorption (H); (DFG 2004). 

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 will be reached rather slowly on evaporation of this substance at 20°C. 

Effects of short-term exposure
The substance is mildly irritating to the eyes and skin. 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
