PHYSICAL STATE; APPEARANCE:
VISCOUS COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating producing toxic and corrosive fumes including acetic acid fumes , hydrogen sulfide and sulfur oxides . Reacts violently with strong acids and strong oxidants to produce hydrogen sulfide .

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


ROUTES OF EXPOSURE:


INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.

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

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
