Enhanced Respirable Crystalline Silica Analysis Surpasses Previous Reporting Limits

Post by:

Although respirable silica has been regulated for decades, the Occupational Health and Safety Administration (OSHA) put new guidelines into place in 2016, updating the existing 1971 rules. Across most industries, the new PEL level is 50 µg/m3 over an eight-hour shift, with an action level of 25 µg/m3. Our AIHA accredited laboratory provides sampling media […]

OSHA has proposed new standards for respirable crystalline silica exposure and a new uniform airborne permissible exposure limit (PEL), calculated as an eight-hour time-weighted average. The agency has identified 25 industry subsectors encompassing approximately 130 industrial and maritime operations in which exposure to respirable crystalline silica is common during operations such as cutting and grinding […]
