| 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 | |||
|
Boiling point: 300.8°C Melting point: 50.0°C Density: 1.12 g/cm^3 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 | ||
| ENVIRONMENTAL DATA | |||
|
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.
