CHEMICAL DANGERS:


OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: ppm; 2 mg/m3 as TWA (ACGIH 1993-1994).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

EFFECTS OF SHORT-TERM EXPOSURE:


EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the lungs , resulting in talc pneumoconiosis.
