Operators in determining the adequacy of their control measuresĪnd in planning for effective monitoring of their employees'Įxposure, MSHA is preparing general guidance materials. The only sure way to determine theĮffectiveness of these engineering controls is to conductĪirborne contaminant sampling on a regular basis. Levels of employee exposure to silica dust as well as otherĮngineering controls are the most effective and reliable methodįor assuring that individuals are not exposed to unhealthful This sampling is conducted to determine theĪdequacy of measures that have been implemented to control the Reminded operators of their obligation under 30 CFR 56.5002 andĥ7.5002 (exposure monitoring) to conduct sampling as frequentlyĪs necessary.
