NSSGA is pleased to Part 1 of an interactive webinar series on medical surveillance programs for workers with silica dust exposures. A medical surveillance program is a significant part of an occupational health program for workers exposed to silica dust, is required to be offered under the Occupational Safety and Health Administration (OSHA) silica standard and is expected to be included in the upcoming Mine Safety and Health Administration (MSHA) rule on silica dust.
