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.    Use water spray, foam, powder, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST! STRICT HYGIENE!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation   Use 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.  Wear 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 refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: chemical protection suit and particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT let this chemical enter the environment.

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

IMPORTANT DATA
Physical State; Appearance
WHITE SOLID IN VARIOUS FORMS WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic gases including hydrogen chloride and phosgene. Reacts with strong oxidants. 

Occupational exposure limits
TLV: 0.2mg/m³ as TWA; (skin); (ACGIH 2004).
MAK: Skin absorption (H); (DFG 2004). 

Routes of exposure
The substance can be absorbed into the body by inhalation of fume 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 skin. 

Effects of long-term or repeated exposure
May cause chloracne. The substance may have effects on the liver. This may result in liver impairment. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 344-388°C
Melting point: 137°C
Density: 1.78 g/cm³
Solubility in water: none
Vapour pressure, Pa at ?°C: <0.01
Relative vapour density (air = 1): 11.6
Octanol/water partition coefficient as log Pow: 7.59  
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 is persistent. The substance may cause long-term effects in the aquatic environment. 

NOTES
Halowax is a trade namefor chlorinated naphthalenes.
