IMPORTANT DATA
Physical State; Appearance YELLOW TO GREEN TO BLUE TO BLACK CRYSTALS, DEPENDING ON PURITY
Occupational exposure limits TLV: (as inhalable dust) 10 mg/m³ as TWA; TLV: (as respirable dust) 3 mg/m³ as TWA; (ACGIH 2004). MAK: (respirable fraction of the aerosol) 1.5 mg/m³; (DFG 2004).
Inhalation risk A nuisance-causing concentration of airborne particles can be reached quickly when dispersed.
Effects of short-term exposure May cause mechanical irritation.

NOTES
This card does not apply to silicon carbide in "fibrous" or "whisker" form. Carborundum is a trade name. There is evidence of fibrosis in mixed dust situations, the risk of which is enhanced in persons with tuberculosis. There is no evidence that silicon carbide (non-fibrous) causes fibrosis in the absence of other dusts.
