What is Respirable Crystalline Silica? Crystalline silica is a common mineral found . in many naturally occurring and man-made . materials used at construction sites. Materials like sand, concrete, brick, block, stone and mortar contain crystalline silica. Amorphous silica, such as silica gel, is not crystalline silica.

Silica. Print. Photo by NIOSH. Millions of U.S. workers are exposed to respirable crystalline silica (RCS) in a variety of industries. Silica dust is made up of small particles that can become airborne during work activities with materials that contain silica. Particles that are small enough to be inhaled deep into the lungs are called respirable.

The proposed rule, Lowering Miners' Exposure to Respirable Crystalline Silica and Improving Respiratory Protection, would set the permissible exposure limit of respirable crystalline silica at 50 micrograms per cubic meter of air (µg/m3) for a full shift exposure, calculated as an 8-hour time weighted average, for all miners.
