It's More Than Dust
Inhalation of excess amounts of respirable crystalline dust can lead to worker illness such as silicosis (type of lung cancer), COPD, pneumoconiosis, and kidney disease.WP), a potentially disabling lung disease.

Real-time Results of Particulate Matter

How Big is Particulate Matter (PM)? 

Respirable Dust is measured in Particulate Matter (PM)

  • PM4 Respirable Crystalline Dust
  • PM10 Thoracic Dust (Dust, Pollen, Mold)
  • PM100 Inhaleable Dust
  • PM500 Table Salt
  • PM1000 United States Dime

What is important to know about measuring 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.
