Sampling must be similar to those likely to be experienced by the Samples be representative of a miner's normal, typical workĪctivity and exposure so that overexposures can be prevented.Ĭonditions within the work environment on the day or week of The objective of all sampling strategies is that the collected Number of samples required to evaluate the exposureĪvailability of sample analytical facilitiesĪvailability of personnel for surveillance Miner location, nature of work operations/exposure duration The following basic considerations can be used to help develop a Strategy or plan for all work and exposure situations, and theĬhoice of a strategy should be based on site-specific conditions. Measuring occupational health hazards and determining the needįor environmental controls. The collection of valid exposure measurements is necessary for The following gives an overview of the basic elements of a mine Seeking appropriate assistance in the recognitionĪnd control of health hazards in the work environment. Implementing adequate and appropriate hazard control Interpreting environmental sampling results and determining A successful program involves the recognition,Įvaluation and control of health hazards in the work environment.Įvaluating the work environment by examining work operationsĪnd processes, determining the presence of hazards, and Prevented by limiting miner exposure to physical and chemical The ultimate goal of mine operator sampling activities is the Monitoring and control measures taken in regard to hazardous Representatives in understanding or otherwise questioning various This information may also assist affected miners and their ![]() Monitoring of their employees' exposures to silica dust and otherĪirborne contaminants, and in determining the various needs forĪnd adequacy of control measures required by 30 CFR 56/57.5002. Material to assist mine operators in planning for effective The following information has been prepared as basic guidance Theįollowing is the first in the series and is intended to provideĪn introduction to the subject of operator air sampling programs. 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.
