Important Data
|
Physical State; Appearance:
ODOURLESS,
COLOURLESS CRYSTALLINE POWDER.
Physical Dangers:
Dust explosion possible if in powder or granular form, mixed with air.
Chemical Dangers:
On combustion, forms irritating fumes of maleic anhydride.
Occupational Exposure Limits:
TLV not established.
|
Routes of Exposure:
The substance can be absorbed into the body
by ingestion.
Inhalation Risk:
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly.
Effects of Short-Term Exposure:
The substance
irritates the eyes, the skin and the respiratory tract.
Effects of Long-Term or Repeated Exposure:
|
|
Physical
Properties
|
Sublimation point: 200°C

|
|
Environmental
Data
|
|
|
N O T E S
