Personal Air Monitoring For Silica

Msha requires regular sampling of sand and gravel pits rock crushers aggregate recycling and stone quarries personal.

Personal air monitoring for silica.

As this new rule for respirable crystalline silica exposure takes effect customers have asked the raeco rents team for help with the proper personal monitoring instruments. 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. Option 2 perform air monitoring. 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.

Since the new osha respirable crystalline silica rule was issued many health and safety professionals have had to evaluate how they will achieve compliance. How do you monitor silica dust. For more information on the sm 4000 personal silica monitor contact your local air met office. 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.

The type of air monitor used to measure crystalline silica exposure and the level of crystalline silica exposure requiring respiratory protection is dependent on the size of the crystalline silica particles being generated. 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. 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. Sampling involves the use of a pump to collect a sample onto a filter that can be sent to a lab for analysis.

The parameters of determining how to monitor for crystalline silica exposure can be found in in 29 cfr 1910 1053. 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. To sample worker exposure personal sampling diffusion detector tubes vapor monitoring badges or personal air sampling pumps are all potential options. New regulations are changing standards for silica dust exposure.
