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).

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV not established.
PDK not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol, through the skin or 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, kidney, oestrogens concentration and testes. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction.
