Introduction. Crystalline silica is the name for a group of naturally occurring minerals found in many types of rock. It can be released into the air when the rock or articles made from the rock are crushed, cut, or worked in some other way. It is the fine fraction of the dust, the respirable fraction, that is harmful to health when inhaled.
However, the handling of such silica waste should be done in a manner to minimize employee exposure to respirable silica dust. Unless employee exposure will remain below the action level of 25 µg/m 3 as an 8-hour time-weighted average (TWA) under any foreseeable conditions, ...
