TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.		Water spray, foam, powder, carbon dioxide.
EXPLOSION

EXPOSURE		PREVENT DISPERSION OF DUST! STRICT HYGIENE!	IN ALL CASES CONSULT A DOCTOR!
Inhalation		Local exhaust or breathing protection.	Fresh air, rest.
Skin	MAY BE ABSORBED! Redness. Pain.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes	Redness. Pain.	Face shield or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion		Do not eat, drink, or smoke during work.	Rinse mouth. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment. Chemical protection suit. Personal protection: P2 filter respirator for harmful particles.

EMERGENCY RESPONSE	SAFE STORAGE
	Separated from strong oxidants, food and feedstuffs.

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/m³; (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 20°C 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	ENVIRONMENTAL DATA
Boiling point: 327-371°C Melting point: 120°C Density: 1.7 g/cm³ Solubility in water: none Vapour pressure, Pa at 20°C: <0.1 Relative vapour density (air = 1): 10.4 Octanol/water partition coefficient as log Pow: 8.73-9.13	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.
