FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Powder, water spray, foam, carbon dioxide.
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.

EXPOSURE
PREVENT DISPERSION OF DUST!

Inhalation Cough. Sore throat. Blue lips or finger nails. Blue skin. Headache. Dizziness. Nausea. Confusion. Convulsions. Unconsciousness.
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention. See Notes.
Skin MAY BE ABSORBED! Redness. Blue lips or fingernails. Blue skin. (Further see Inhalation).
Protective gloves. Protective clothing.
Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes Redness.

IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS, WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
Dust explosion possible if in powder or granular form, mixed with air.

CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing toxic fumes including nitrogen oxides. Reacts with strong oxidants and strong acids.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 10 mg/m as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2005).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes, the skin and the respiratory tract. The substance may cause effects on the blood, resulting in formation of methaemoglobin. See Notes.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the kidneys and blood, resulting in the formation of methaemoglobin.
PHYSICAL PROPERTIES

Vapour pressure, Pa at 108C: 133
Relative vapour density (air = 1): 5.8
Flash point: 153C c.c.
Auto-ignition temperature: 634C
Octanol/water partition coefficient as log Pow: 3.34
ENVIRONMENTAL DATA
The substance is toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment.
NOTES
Technical product may contain a carcinogenic impurity (4-aminobiphenyl). 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.
The cards has been partly updated in April 2005. See sections Environmental Data, EU classification, Occupational Exposure Limits.
