NRMCA Executive Vice President, Compliance & Operations Gary Mullings and Vice President, Compliance & Regulatory Affairs Kevin Walgenbach review raw materials, plant conditions, housekeeping measures, worker protection, exposure monitoring and best compliance practices in “Guide for Silica Regulations and the Ready Mixed Concrete Industry.”
Based on the Occupational Health and Safety Administration’s “Small Entity Compliance Guide for the Respirable Crystalline Silica Standard for General Industry and Maritime,” the document was prepared to help producer members abide agency regulations effective June 23, 2018. The General Industry standard (1910.1053) for silica exposure follows a companion Construction (1926.1153) standard effective September 2017. Both lower thresholds for silica exposure and establish new workplace or site monitoring procedures.
