PHYSICAL STATE; APPEARANCE:
COLOURLESS TO YELLOW SOLID IN VARIOUS FORMS

PHYSICAL DANGERS:


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

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK:
Carcinogen category: 2;
(DFG 2003).
OSHA PEL: none
NIOSH REL: Ca* See Appendix A *Note: Since metabolized to beta-Naphthylamine.
NIOSH IDLH: Ca N.D. See: IDLH INDEX


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and by ingestion.

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the blood , resulting in the formation of methaemoglobin. Medical observation is indicated. The effects may be delayed.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point: 304°C
Melting point: 79°C
Solubility in water, g/100 ml at °C:
very poor
Vapour pressure, kPa at 25°C: 0.000032
Relative vapour density (air = 1): 5.89
Octanol/water partition coefficient as log Pow: 2.78

ENVIRONMENTAL
DATA


N O T E S

Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. Similar substances cause bladder tumours in humans. See ICSC 0610 2-Naphthylamine.
