Application Spotlight

Testing for Respirable Silica

In 2024, the Mine Safety and Health Administration (MSHA) significantly lowered the permissible exposure limit (PEL) for respirable crystalline silica. Mine operators must routinely collect and submit air samples using a cyclone sampler with filter cartridge or a disposable parallel particle impactor (PPI). To maintain compliance and profitability, operators need an experienced partner for testing and analysis of air samples who can provide fast, accurate, and dependable results. 

The geologists and EH&S professionals at RJ Lee Group have been helping keep miners safe for over 40 years. We conduct on-site and off-site testing, help develop in-house laboratory capabilities, set up structured compliance timelines, and conduct routine audits tailored to align with MSHA standards. 

  • X-Ray Diffraction (XRD) equipment to process samples faster and with greater resolution.

  • Sensitivity to detect silica at very low limits, allowing us process samples from even a short duration exposure.

  • Experienced geologists to identify iterferences including mica, clays, kaolin, feldspar, graphite, and other minerals for greater accuracy and identification of other hazards.

  • Processing of bulk samples and air samples.

  • Rapid turnaround times at competitive prices.
