TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use water spray, foam, powder, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation   Use local exhaust or breathing protection.  Fresh air, rest. 
Skin Redness.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Nausea. Vomiting.  Do not eat, drink, or smoke during work.   

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Sweep spilled substance into covered 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. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance.

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

IMPORTANT DATA
Physical State; Appearance
COLOURLESS-TO-YELLOW SOLID IN VARIOUS FORMS WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic and corrosive fumes including hydrogen chloride. Reacts with oxidants. This generates fire hazard. 

Occupational exposure limits
TLV: 5mg/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
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. 

Effects of short-term exposure
The substance is mildly irritating to the eyes and skin. 

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

Bioaccumulation of this chemical may occur along the food chain, for example in crustacea. Bioaccumulation of this chemical may occur 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.
The health effects may vary with the proportion of the different isomers present.
Card has been partly updated in April 2005. See section Occupational Exposure Limits.
