PHYSICAL STATE; APPEARANCE:
ODOURLESS, COLOURLESS LIQUID.

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance decomposes on burning producing irritating fumes .

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 by ingestion.

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