PHYSICAL STATE; APPEARANCE:
PALE YELLOW, ODOURLESS POWDER.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on burning producing toxic and corrosive gases including carbon oxides, nitrogen oxides, sulfur oxides.

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 and through the skin.

INHALATION RISK:
Evaporation at 20C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may irritate the eyes, the skin and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization.
PHYSICAL
PROPERTIES
