PHYSICAL STATE; APPEARANCE:
WHITE OR COLOURLESS FLUFFY CRYSTALS

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance decomposes on heating and under the influence of UV light producing toxic and corrosive fumes, including hydrogen chloride (See ICSC 0163) and nitrogen dioxide (See ICSC 0930) .

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK 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:
A nuisance-causing concentration of airborne particles can be reached quickly when dispersed

EFFECTS OF SHORT-TERM EXPOSURE:
May cause mechanical irritation.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
