IMPORTANT DATA
Physical State; Appearance WHITE, GREY. GREEN OR YELLOWISH FIBROUS SOLID.
Routes of exposure The substance can be absorbed into the body by inhalation.
Occupational exposure limits TLV: 0.1 fibres/cc (as TWA) A1 (ACGIH 1998. For fibres longer than 5 um with an aspect ratio equal to or greater than: 3:1 as determined by the membrane filter method at 400-450X magnefication (4-mm objective) phase contrast elimination). MAK: class III A1 (1993) 0.6 fibres/cm3 EC OELs
Inhalation risk Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.
Effects of long-term or repeated exposure The substance may have effects on the lungs, resulting in pulmonary fibrosis and mesothelioma. This substance is carcinogenic to humans.
Melting point (decomposes): see Notes Density: 2.2-2.6 g/cm3
PHYSICAL PROPERTIES
