PHYSICAL STATE; APPEARANCE:
CRYSTALLINE POWDER.




CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing toxic fumes (phosgene - see ICSC # 0007, hydrogen chloride - see ICSC # 0163). Reacts violently with dimethylformamide in the presence of iron.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.

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 irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system. Exposure may result in death.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the blood, liver. This substance is possibly carcinogenic to humans.
PHYSICAL
PROPERTIES
 Boiling point: 288°C
Melting point: 156-161°C
Relative density (water = 1): 1.87
 Solubility in water: none
Vapour pressure, Pa at 20°C: 3
Octanol/water partition coefficient as log Pow: 3.82
ENVIRONMENTAL
DATA
 This substance may be hazardous to the environment; special attention should be given to water organisms and shellfish. In the food chain important to humans, bioaccumulation takes place, specifically in seafood.
NOTES
This compound is a component of the insecticide hexachlorocyclohexane (mixed isomers). It is not commercially formulated alone. Data are insufficiently available on the effect of this substance on human health, therefore utmost care must be taken. Do NOT take working clothes home. Also consult ICSC # 0487.
