OSHA’s Proposed Rule Against Toxic Silica Dust

By Williams & Brown LLP on November 29, 2013

Waco Toxic Tort AttorneyThe Occupational Safety and Health Administration (OSHA) has proposed a new safety regulation that would drastically reduce the exposure limit for airborne crystalline silica in all industries. The toxic dust has been linked to silicosis, an incurable and often fatal lung disease that threatens nearly 2.2 million workers in the U.S.

What is Silica?

Silica is a mineral found in sand, rock, and other ores, such as quartz, which are commonly used in a wide range of industrial operations.

Silica can become a fine, airborne dust as a result of cutting, grinding, or abrasive blasting of objects that contain the mineral. Exposure to respirable silica most often occurs in construction, mining, manufacturing, and maritime work.

The Dangers of Crystalline Silica

When silica dust enters the lungs it causes the formation of scar tissue and greatly reduces the lungs’ ability to absorb oxygen, which significantly contributes to the risk of silicosis, tuberculosis, chronic bronchitis, and renal disease, among other illnesses. Workers that are regularly exposed to airborne crystalline silica can develop serious health consequences over a period of only a few months to several years.

Taking Action

The proposed rule would reduce the permissible exposure limit (PEL) for crystalline silica to 50 micrograms over an 8-hour work day for workers. In addition, the proposed rule would include the following provisions:

  • Limiting workers’ access to areas of high silica exposure,
  • Providing medical exams to workers with high levels of exposure, and
  • Training for workers about silica dangers and how to reduce exposure.

OSHA has invited the public to participate in developing the final rule by submitting comments and attending public hearings. For more information, please visit:
