Silica Air Monitoring Equipment

New regulations are changing standards for silica dust exposure.

Silica air monitoring equipment.

The chosen method will guide you through. Control of silica will start with employers identifying and quantifying respirable silica exposure. 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 i know what air monitoring equipment to use.

The work practices used. All employees may be fitted with the sampling device or just a select few who are closest to the silica source may be fitted. The parameters of determining how to monitor for crystalline silica exposure can be found in in 29 cfr 1910 1053. A sample pump collect an air sample by pulling air through a cyclone.

The proper respirable silica sampling equipment is available to you through our popular freepumploan program. Approved sampling methods developed by niosh osha and msha exist for crystalline silica sampling. 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. Whether an employer s air monitoring data accurately reflect current exposures depends on several factors including the degree to which exposures vary by day shift or process.

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. Each method incorporates the use of a cyclone sampler. And the condition of the equipment. Sampling involves the use of a pump to collect a sample onto a filter that can be sent to a lab for analysis.

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. The cyclone assembly and sampling pump will be placed on an employee who will wear the device throughout the work shift for up to 8 hours. Measuring silica with gravimetric sampling and real time monitoring how is gravimetric sampling done for respirable crystalline silica. Choosing the right sampling pump.

Appendix a to 29 cfr 1910 1053 identifies the methods to follow for a collection of a respirable silica sample. Different cyclones allow differently sized particles to pass through. How do you monitor silica dust. See 81 fr 16763 march 25 2016.
