CHLORDANE (TECHNICAL PRODUCT) ICSC: 0740
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
TECHNICAL: LIGHT YELLOW TO AMBER VISCOUS LIQUID

CHEMICAL DANGERS:
The substance decomposes on burning, on contact with bases producing toxic fumes including phosgene, hydrogen chloride. Attacks iron, zinc, plastic, rubber and coatings.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.5 mg/m as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2004).
MAK: (Inhalable fraction) 0.5 mg/m; Peak limitation category: II(8); skin absorption (H); Carcinogen category: 3B; (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

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

EFFECTS OF SHORT-TERM EXPOSURE:
Exposure at high levels may result in disorientation, tremors, convulsions, respiratory failure and death. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the liver and immune system, resulting in tissue lesions and liver impairment. This substance is possibly carcinogenic to humans.
PHYSICAL PROPERTIES
Boiling point at 0.27kPa: 175C
Relative density (water = 1): 1.59-1.63
Solubility in water: none
Vapour pressure, Pa at 25C: 0.0013
Octanol/water partition coefficient as log Pow: 2.78
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to soil organisms, honey bees. It is strongly advised that this substance does not enter the environment. The substance may cause long-term effects in the aquatic environment.
NOTES
If the substance is formulated with solvents also consult the ICSCs of these materials. Carrier solvents used in commercial formulations may change physical and toxicological properties. Belt, Chlor Kil, Chlortox, Corodan, Gold Crest, Intox, Kypchlor, Niran, Octachlor, Sydane, Synklor, Termi-Ded, Topiclor, and Toxichlor are trade names. Also consult ICSC 0743 Heptachlor. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, Emergency Response.
