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/m³ 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 20°C; 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	ENVIRONMENTAL DATA
Boiling point: 284-287°C Melting point: 62-63°C Density: 1.14 g/cm³ Solubility in water: soluble Vapour pressure, Pa at 99.8°C: 133 Relative vapour density (air = 1): 3.7 Flash point: 187°C c.c. Auto-ignition temperature: 560°C Octanol/water partition coefficient as log Pow: -0.33	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.
