It's More Than Dust
OSHA Lowers the Permissible Exposure Limit (PEL)
The PEL for respirable crystalline silica is 50 μg/m3 (micrograms of silica per cubic meter of air) averaged over eight hours called Time Weighted Average (TWA). Worker direct exposure is identified through laboratory analysis of the sample. If the sample result is above the PEL, employers must resample every three months.
Action Level of 25 μg/m3 TWA
Employers are not required to monitor for silica if they can demonstrate the occupational exposure is below the Action Level, TWA, of 25 μg/m3. If employers are above the Action Level, the employer must resample every six months.
Laboratories Must Analyze Silica Samples
Air samples must be analyzed by certified laboratories that use specific sampling and analytical methods.
Written Exposure Plan
The Exposure Plan must be 1) written for each facility, 2) reviewed and updated annually, 3) work positions or technology used to reduce exposures must be listed, and 4) must be readily available to all workers. Employers should determine areas with potential for exposure and create regulated areas with limited access.
