OSHA Silica Medical Exam

The following is a summary from the Occupational Safety and Health Administration (OSHA Silica Medical Exam)


Department of Labor – on Occupational Exposure to Respirable Crystalline Silica:


“The Occupational Safety and Health Administration (OSHA) is amending its existing standards for occupational exposure to respirable crystalline silica. OSHA has determined that employees exposed to respirable crystalline silica at the previous permissible exposure limits face a significant risk of material impairment to their health. The evidence in the record for this rule making indicates that workers exposed to respirable crystalline silica are at increased risk of developing silicosis and other non-malignant respiratory diseases, lung cancer, and kidney disease. This final rule establishes a new permissible exposure limit of 50 micrograms of respirable crystalline silica per cubic meter of air (50 μg/m3) as an 8-hour time weighted average in all industries covered by the rule. It also includes other provisions to protect
employees, such as requirements for exposure assessment, methods for controlling exposure, respiratory protection, medical surveillance, hazard communication, and record keeping.

OSHA is issuing two separate standards – one for general industry and maritime, and the other for construction – in order to tailor requirements to the circumstances found in these sectors.”

“The new OSHA rule governing respirable crystalline silica calls for medical surveillance screenings to allow for identification of silica exposure-related health effects in your workers. But who exactly must be surveilled, when and how often do you conduct the surveillance?”
