PENTACHLORONAPHTHALENE ICSC: 0935
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
PALE YELLOW OR WHITE SOLID, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes of hydrogen chloride. Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.5 mg/m; (skin); (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 fumes and through the skin.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

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

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis (chloracne). The substance may have effects on the liver, resulting in liver impairment.
PHYSICAL PROPERTIES
Boiling point: 327-371C
Melting point: 120C
Density: 1.7 g/cm
Solubility in water: none
Vapour pressure, Pa at 20C: <0.1
Relative vapour density (air = 1): 10.4
Octanol/water partition coefficient as log Pow: 8.73-9.13
ENVIRONMENTAL DATA
Bioaccumulation of this chemical may occur along the food chain, for example in fish. It is strongly advised not to let the chemical enter into the environment because it persists in the environment. The substance may cause long-term effects in the aquatic environment.
NOTES
Halowax is a trade name for chlorinated naphthalenes.
Card has been partly updated in April 2005. See section Occupational Exposure Limits.
