  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.    NO open flames.    Use water spray, foam, powder, carbon dioxide.   

 PREVENT GENERATION OF MISTS! AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Blue lips, fingernails and skin. Headache. Dizziness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Administration of oxygen may be needed. Refer immediately for medical attention. See Notes. 
Skin MAY BE ABSORBED! Further see Inhalation.  Protective gloves. Protective clothing.  Administration of oxygen may be needed. Remove contaminated clothes. Rinse and then wash skin with water and soap. See Notes. Refer immediately for medical attention. 
Eyes Redness. Pain.  Wear face shield or eye protection in combination with breathing protection.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion Nausea. Further see Inhalation.  Do not eat, drink, or smoke during work.  Administration of oxygen may be needed. Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer immediately for medical attention.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
RED-TO-YELLOW OILY LIQUID WITH CHARACTERISTIC ODOUR. TURNS BROWN ON EXPOSURE TO AIR. 

Physical dangers
The vapour is heavier than air and may travel along the ground; distant ignition possible. 

Chemical dangers
Decomposes on burning. This produces toxic fumes including nitrogen oxides, carbon monoxide and carbon dioxide. The solution in water is a weak base. Reacts with acids, chloroformates and strong oxidants. This generates fire and explosion hazard. Attacks some coatings, some forms of plastic and rubber.

Auto-ignition temperature: 430°C
Octanol/water partition coefficient as log Pow: 1.18
Viscosity: 2.028 mm²/s at 55°C 


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 may cause effects on the blood. This may result in the formation of methaemoglobin. See Notes. Exposure could cause haemolysis. This may result in haemolytic anaemia. The effects may be delayed. Medical observation is indicated. 

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

Effects of long-term or repeated exposure
The substance may have effects on the blood. This may result in the formation of methaemoglobin and anaemia. This substance is possibly carcinogenic to humans. 


Occupational exposure limits
TLV: 0.5 mg/m3, - ppm, as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued.
MAK: skin absorption (H); carcinogen category: 2 

ENVIRONMENT
The substance is toxic to aquatic organisms. It is strongly advised not to let the chemical enter into the environment. 

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
See ICSC 0971.
