Personal Air Monitoring For Silica

Approved sampling methods developed by niosh osha and msha exist for crystalline silica sampling.

Personal air monitoring for silica.

How do you monitor silica dust. Option 2 perform air monitoring. The parameters of determining how to monitor for crystalline silica exposure can be found in in 29 cfr 1910 1053. New regulations are changing standards for silica dust exposure.

For more information on the sm 4000 personal silica monitor contact your local air met office. To sample worker exposure personal sampling diffusion detector tubes vapor monitoring badges or personal air sampling pumps are all potential options. Under the rcs standard s scheduled monitoring option employers must conduct initial monitoring to assess the 8 hour twa exposure for each employee on the basis of one or more personal breathing zone air samples that reflect the exposures of employees on each shift for each job classification and in each work area. Sampling the air for respirable silica when a dust producing task is being performed is the best way to determine if and how much silica dust is in the air the worker is breathing.

And of course you re in the best hands as sgs galson currently meets all of the new laboratory qualifications for silica and we re ready to help. The sm 4000 silica monitor is ideal for perimeter monitoring of regulated areas with user set alarms task monitoring recording time history of dust levels and more. The most widely used and preferred option is to connect a battery operated pump to a filter medium tubes and filters to collect the contaminant so it can be analyzed and exposures levels. Msha requires regular sampling of sand and gravel pits rock crushers aggregate recycling and stone quarries personal.

Osha 29 cfr 1926 1153 d 2 v limits exposure the time of exposure to crystalline silica to 50 micrograms per cubic meter of air. Note the final rule reduces the permissible exposure limit for crystalline silica to 50 micrograms per cubic meter of air averaged over an eight hour shift. Since the new osha respirable crystalline silica rule was issued many health and safety professionals have had to evaluate how they will achieve compliance. Seasoned professionals and those new to the silica sampling process have questions on how to achieve the required appropriate exposure monitoring plan or schedule monitoring option.
