This is believed to be …
Respiratory Protective Equipment (RPE) ... This shows how much silica is created when grinding concrete without dust extraction. The Workplace Exposure Limit for silica is 0.1 mg/m 3 when averaged over 8 hours. The work quickly produces high peak exposures of around 1-2 mg/m. Note that this is with a relatively slowly moving grinding disc.
silica standard by using a VDCS to control dust when using a handheld grinder. Use a: • Commercially available shroud and dust collection system on the grinding wheel appropriate for the grinder and wheel size. • Vacuum that provides at least 25 cubic feet per minute (cfm) of airflow per inch of blade to capture dust at the point of grinding.
