Health HazardsExcerpt from NIOSH Pocket Guide for Perlite:
Hazards Summary
No abnormal findings have been documented in workers exposed to perlite alone. [Harber, p. 349] Documentation and TLV withdrawn in 2006 because of insufficient data; [ACGIH] Perlite ores may be contaminated with silica, and cases of complicated mixed-dust pneumoconiosis have been diagnosed in New Mexico perlite workers. [Hendrick, p. 171]
Chemie und Industrie
Verwendung und Herstellung
Uses
A non-crystalline silicate that occurs naturally in volcanic ash deposits; [Harber, p. 349] Perlite consists of small beads of volcanic glass that can be popped, i.e., heated until it expands into a styrofoam-like material that is used in construction products and soil conditioners. [Hendrick, p. 171] Crystalline silica not bound to other minerals is free silica. Silicates are minerals in which silicon and oxygen are combined with other elements. [Rom, p. 364]
