EXPOSURE & HEALTH EFFECTS

Routes of exposure

Effects of short-term exposure
May cause mechanical irritation.

Inhalation risk
A nuisance-causing concentration of airborne particles can be reached quickly when dispersed.

Effects of long-term or repeated exposure

OCCUPATIONAL EXPOSURE LIMITS
TLV: (inhalable fraction): 10 mg/m³, as TWA. TLV: (respirable fraction): 3 mg/m³, as TWA. MAK: carcinogen category: 2

ENVIRONMENT

NOTES
This card does not apply to silicon carbide in "fibrous" or "whisker" form. 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.
