2,4-TOLUENEDIAMINE ICSC: 0582
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS. TURNS DARK ON EXPOSURE TO AIR.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic fumes of nitrogen oxides.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: skin absorption (H); sensitization of skin (Sh); Carcinogen category: 2; (DFG 2005).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol or vapour (when in molten state), through the skin and by ingestion.

INHALATION RISK:
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract. The hot liquid may cause severe skin burns. The substance may cause effects on the liver and blood, resulting in liver damage and formation of methaemoglobin. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization. This substance is possibly carcinogenic to humans. May cause genetic damage in humans.

Octanol/water partition coefficient as log Pow: 0.35
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
May be handled and shipped in the molten state. Density of the solid is unknown in literature, but density of the liquid (water = 1) at 100C is 1.045. 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. Azogen Developer H, Benzofur MT, Eucanine GB, Fouramine, Fourrine, Pelagol, Pontamine Developer TN, Tertral G, Zoba GKE, and Zogen Developer H are trade names. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
