Exposure Control Plan for Cutting, Grinding, and Polishing Stone Containing Crystalline Silica (Quartz) The cutting, grinding, and polishing of stone (, granite) without proper dust controls can generate high levels of silicacontaining dust. Breathing in this fine dust can cause a serious lung disease called silicosis.
The particles are "inorganic" or "organic," depending on the source of the dust. Inorganic dusts can come from grinding metals or minerals such as rock or soil. Examples of inorganic dusts are silica, asbestos, and coal. Organic dusts originate from plants or animals. An example of organic dust is dust that arises from handling grain.

Generally, cutting, grinding, drilling, and polishing stone products with a higher silica content creates larger amounts of very small, crystalline silica dust particles that workers may breathe. Even though silica content is generally lower in natural stone products, workers can be .
However, cutting, grinding, chipping, sanding, drilling, and polishing natural and manufactured stone products can release hazardous levels of very small, crystalline silica dust particles into the air that workers breathe. Working with ground quartz in the countertop manufacturing industry can also expose workers to dangerous silica dust.
May 13, 2014· The requirements of COSHH — the need to assess the risk to workers and to ensure exposure is prevented or adequately controlled — apply when these concentrations of dust in air are exceeded. However, these levels, which were taken from figures developed more than 50 years ago by the American Conference of Government Industrial Hygienists ...
Graphite is widely used in industry, but it carries risks when its dust gets airborne. At certain levels of exposure, graphite is an inhalation hazard. Controlling workplace dust is crucial for protecting workers and for complying with the various regulations that exist for graphite.
That cloud of dust you see when a worker cuts or grinds concrete, brick, or stone is not just harmless dust... It contains crystalline silica... and IT CAN KILL. Most crystalline silica is in the form of quartz. Common sand is almost quartz. Fine particles created by cutting and grinding .

Grinding Stone. Using a vacuum dust . collection system . No engineering controls. NIOSH. Another type of engineering control for silica dust is a vacuum dust collection system. Vacuum dust collection systems remove dust at the point where it is made. These pictures show employees grinding stone, with and without a dust collection system.
The risks are much greater when working with engineered stone, as it contains up to 95 per cent crystalline silica, while natural stone contains 550 per cent. The workplace exposure standard for RCS will be exceeded if the amount of dust a worker breathes over a full shift contains more RCS than the amount shown here next to the five cent piece.
