m-PHENYLENEDIAMINE ICSC: 1302
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALS, TURNS RED ON EXPOSURE TO AIR.

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

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.1 mg/m as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK: skin absorption (H); Carcinogen category: 3B; (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20C; on spraying or dispersing, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes and the skin. The substance may cause effects on the kidneys and blood, resulting in renal failure 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. The substance may have effects on the kidneys, resulting in renal failure.
PHYSICAL PROPERTIES
Boiling point: 284-287C
Melting point: 62-63C
Density: 1.14 g/cm
Solubility in water: soluble
Vapour pressure, Pa at 99.8C: 133
Relative vapour density (air = 1): 3.7
Flash point: 187C c.c.
Auto-ignition temperature: 560C
Octanol/water partition coefficient as log Pow: -0.33
ENVIRONMENTAL DATA
The substance is toxic to aquatic organisms.
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. Direct Brown BR, Direct Brown GG, Developer C, Developer H, Developer M, Developer 11 are trade names. See also ICSC0805 p-Phenylenediamine.
Card has been partly updated in October 2004 and April 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
