Silica sand: This product is a potentially serious health hazard and should not be used as an abrasive. If silica containing (quartz) materials are selected for any reason, workers must wear a positive pressure or pressure demand respirator with an assigned protection factor (APF) of either 1000 or 2000.
Jun 17, 2020· To start, they must pay close attention to OSHA standards surrounding silica dust. For example, the exposure limit is 50 micrograms per cubic meter of air during a typical shift. That means supervisors need to ensure that silica dust levels are kept low, or that they provide proper protective equipment (PPE) to prevent inhalation.
OSHA Construction Standard. On March 24, 2016, OSHA issued a final silica standard for the construction industry.

Unimin 100 lb. Silica Sand is renowned for quality, uniformity and consistency. It has a 4060 grade (60% retained on 40 mesh or coarser) and a 2. 0 MILS surface profile when used as an abrasive. Its effective size in filtration is 0. 35 mm.
In 1974, the United States was poised to adopt a ban on silica sand for abrasive blasting on the recommendation of the National Institute for Occupational Safety and Health (NIOSH), but as discussed in our article on the Silica Rule, political forces hampered adoption, and wet abrasive blasting technology failed to find a foothold in North America.
Sep 25, 2014· Breathing sharp, freshly-cut sand dust, such as silica at sand mining and processing sites, carries a greater risk of pulmonary disease than breathing older, smoother particles weathered by heat, wind, and moisture – such as silica dust blown from cropland.
