0351 ALUMINIUM OXIDE
IMPORTANT DATA
Physical State; Appearance Routes of exposure
WHITE POWDER. The substance can be absorbed into the body by inhalation of
its aerosol.
Occupational exposure limits
TLV: 10 mg/m3 (as TWA) A4, for particulate matter containing Inhalation risk
no asbestos and 1% crystalline silica (ACGIH 2000). Evaporation at 20掳C is negligible; a harmful concentration of
MAK: 1.5 mg/m3; respirable fraction of the aerosol (1999) airborne particles can, however, be reached quickly.
MAK: class II,2 (1999)
Effects of short-term exposure
Inhalation of high concentrations of dusts of this substance may
cause eyes and upper respiratory tract irritation.
Effects of long-term or repeated exposure
The substance may have effects on the central nervous
system.
