PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALS , WITH CHARACTERISTIC ODOUR. TURNS RED ON EXPOSURE TO AIR, LIGHT AND MOISTURE.

PHYSICAL DANGERS:


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.
OSHA PEL: 1910.1004 See Appendix B
NIOSH REL: Ca See Appendix A
NIOSH IDLH: Ca N.D. See: IDLH INDEX


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.

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.

N O T E S

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.
