SilicaCutting and grinding concrete Use a respirator. An N95 filtering facepiece respirator i.e., dust mask may be appropriate when doing shortduration tasks, when local exhaust ventilation is available on tools, or when working outside. Otherwise, a more protective respirator is required. Minimum
If no dust extraction is available for drilling or grinding, running a water hose onto the surface or holding a vacuum up to the tool will keep dust down. Use a drill dust attachment by turning the vacuum on and sticking the attachment to the surface. The suction from the vacuum should hold it in place.
Concrete cutting and concrete grinding are very dusty jobs in the construction industry, both posing a serious health risk to masons. Masonry blocks, bricks, and concrete slabs contain concentrated amounts of crystalline silica. When these materials are drycut they release silica containing dust into the workers breathing zone. Regular exposure to this hazardous dust can
Crystalline silica is found widely in construction materials such as concrete, cement, mortar, brick and stone. When these materials are cut, drilled or ground, they produce dust that may contain small, respirable particles of crystalline silica, which has been linked to serious respiratory diseases like silicosis and COPD.
Silica Rule With OSHA39s new Silica Rule for roadway construction activies now being enforced, companies engaged in roadway construction must be aware of the potential for exposure to silica associated with common roadway construction activities, mitigation strategies and technologies, and reporting, monitoring, and other regulatory obligations.
