TETRACHLORONAPHTHALENE ICSC: 1387
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS TO PALE YELLOW CRYSTALS, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic gases (hydrogen chloride, phosgene). Reacts with strong oxidants causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 2 mg/m as TWA; (ACGIH 2004).
MAK: IIb (not established but data is available); skin absorption (H); (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its fumes and through the skin.

INHALATION RISK:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20C; on spraying or dispersing, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is mildly irritating to the eyes and the skin.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the liver, resulting in liver impairment.
PHYSICAL PROPERTIES
Boiling point: 312-360C
Melting point: 182C
Density: 1.6 g/cm
Solubility in water: none
Vapour pressure, Pa at 25C: < 0.1
Relative vapour density (air = 1): 9.2
Flash point: 210C o.c.
Octanol/water partition coefficient as log Pow: 5.75-6.19
ENVIRONMENTAL DATA
Bioaccumulation of this chemical may occur in fish. It is strongly advised that this substance does not enter the environment. The substance may cause long-term effects in the aquatic environment.
NOTES
Halowax is a trade name for chlorinated naphthalenes. The health effects may vary with the proportion of the different isomers present.
