TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames. NO contact with oxidizing agents.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION Risk of fire and explosion on contact with acids or oxidizing agents.    In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   PREVENT GENERATION OF MISTS! STRICT HYGIENE!   
Inhalation Headache. Blue lips, fingernails and skin. Dizziness. Laboured breathing.  Use local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. 
Skin MAY BE ABSORBED! Further see Inhalation.  Protective gloves. Protective clothing.  Rinse and then wash skin with water and soap. Refer for medical attention . Wear protective gloves when administering first aid. 
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 Abdominal pain. Further see Inhalation.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Refer for medical attention .

Physical dangers
 

Chemical dangers
Decomposes on contact with strong oxidants, reducing agents, acids or bases. This produces toxic fumes. This generates fire and explosion hazard. Attacks some forms of plastic, rubber and coatings. On combustion, forms nitrogen oxides and carbon monoxide. 

Occupational exposure limits
TLV: 2ppm as TWA; (skin); BEI issued; (ACGIH 2005).
MAK: Carcinogen category: 2; Germ cell mutagen group: 3B; Skin absorption (H); (DFG 2008). 

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol, 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 irritating to the eyes. 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
The substance may have effects on the liver, blood and testes.
