  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Risk of fire and explosion on contact with acids or oxidizing agents.  NO open flames. NO contact with oxidizing agents.  NO contact with incompatible materials: See Chemical Dangers  Use water spray, powder, foam, carbon dioxide.   

 PREVENT GENERATION OF MISTS! AVOID ALL CONTACT!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Headache. Blue lips, fingernails and skin. Dizziness. Shortness of breath.  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.  Wear protective gloves when administering first aid. 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 Abdominal pain. Further see Inhalation.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Refer for medical attention .

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
YELLOW-TO-COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. 

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.

EXPOSURE & HEALTH EFFECTS

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

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

Inhalation risk
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C. 

Effects of long-term or repeated exposure
The substance may have effects on the liver, blood and testes. This substance is probably carcinogenic to humans. May cause heritable genetic damage to human germ cells. Animal tests show that this substance possibly causes toxic effects upon human reproduction. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 2 ppm as TWA; (skin); BEI issued.
MAK: skin absorption (H); carcinogen category: 2; germ cell mutagen group: 3B 

ENVIRONMENT
The substance is toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. It is strongly advised not to let the chemical enter into the environment. 

NOTES
Specific treatment may be necessary in case of poisoning with this substance; the appropriate means with instructions should be available.
Do NOT take working clothes home.
Depending on the degree of exposure, periodic medical examination is suggested.
