IMPORTANT DATA

Physical State; Appearance
WHITE CRYSTALS, WITH CHARACTERISTIC ODOUR. TURNS RED ON EXPOSURE TO AIR, LIGHT AND MOISTURE.

Chemical dangers
The substance decomposes on burning producing nitrogen oxides and carbon monoxide.
The substance is a weak base.

Occupational exposure limits
TLV not established. MAK not established.

Routes of exposure
The substance can be absorbed into the body by inhalation and through the skin and by ingestion.

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

Effects of short-term exposure
The substance is mildly irritating to the eyes and the skin. The substance may cause effects on the blood, resulting in the formation of methaemoglobin. The effects may be delayed. Medical observation is indicated. See Notes.

Effects of long-term or repeated exposure
See Notes.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 300.8°C Melting point: 50.0°C Density: 1.12 g/cm³ Solubility in water: none Vapour pressure, Pa at 20°C: 0.53 Relative vapour density (air = 1): 4.93 Flash point: 157°C c.c. Auto-ignition temperature: 460°C Octanol/water partition coefficient as log Pow: 2.25	The substance is harmful to aquatic organisms. It is strongly advised not to let the chemical enter into the environment because it persists in the environment.

NOTES

Depending on the degree of exposure, periodic medical examination is indicated.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Bladder cancers reported after occupational exposure to 1-naphthylamine may be due to contamination with 2-naphthylamine which is a human carcinogen.
