ICSC: 1708

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALLINE POWDER

CHEMICAL DANGERS:
The substance decomposes on heating, producing toxic and corrosive gases including hydrogen chloride. Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established. MAK not established.

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

INHALATION RISK:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes, the skin and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the liver, resulting in impaired functions.
