Crystalline silica is found in sand, stone, concrete and mortar. When workers cut, crush, drill, polish, saw or grind products containing silica, dust particles are generated that are small enough to lodge deep in the lungs and cause illness or disease including silicosis.
Materials like sand, concrete, stone and mortar contain crystalline silica. Crystalline silica is also used to make products such as glass, pottery, ceramics, bricks, concrete and artificial stone. Industrial sand used in certain operations, such as foundry work and hydraulic fracturing (fracking), is also a source of crystalline silica exposure.
Oct 20, 2014· The effect of cumulative silica dust exposure on airflow obstruction is independent of silicosis. Pulmonary siderosis. Those who work with metal grinding or welding have a risk of inhalation of metallic particles. Iron absorbs X-rays and produces very impressive shadows on CXR but it has little effect on pulmonary function and little long-term ...
Specifically, workers who transport, handle, process, polish, ground, or shape a variety of workplace materials can be exposed to combustible dust. Workers can also release combustible dust when they take part in abrasive blasting, cutting, crushing, mixing, sifting, or screening dry materials. Common sources of combustible dust are as follows:
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.
For businesses in the stone benchtop industry, the Managing respirable crystalline silica dust exposure in the stone benchtop industry Code of Practice 2019(PDF, 930.96 KB) sets out the minimum standards that must be met for respiratory protective equipment for workers–stone benchtop fabrication workers must wear a powered air purifying ...
Dec 08, 2015· When materials such as concrete, stone, brick, or granite are cut or ground by workers, it can create extremely fine dust particles, which can make their way deep into the lungs if inhaled. These silica dust particles can cause scarring in the lungs, leading to a serious and irreversible lung condition known as silicosis.
Assessment of work involving other types of grain dust 17 You may need to carry out a risk assessment of work activities involving exposure to other types of grain not included in the definition of grain dust, eg rice, sorghum, pulses (such as soya bean), peas and various oilseeds (such as rapeseed).
Aug 07, 2017· In a decision that is estimated to save over 600 worker lives every year,* the Occupational Safety and Health Administration, or OSHA, passed new legislation in 2016 that will limit worker exposure to crystalline silica dust.

Assessment NIOSH scientists visited Stone Systems of Minnesota, Mendota Heights, MN on August 25-26, 2015. During the site visit, they performed industrial hygiene sampling which measured the short term task-based exposures to respirable dust and respirable crystalline silica of six workers who used handheld tools in the stone
Wood dust is one of the oldest occupational exposures known to man, and it's still very important to today for those who have jobs ranging from cabinetry to mill workers. Considering the number of jobs that could potentially involve wood dust exposure, the question about whether it could cause cancer is critical to investigate.
dust, powder or paste - such as wood, cement, metal, flour, grain, rubber or stone dust. This risk of harm may be increased if any of your employees have pre-existing health conditions such as asthma. Workers can also become sensitised to the substances they are exposed to. The exposures can come from a wide variety of work situations such as
There is some evidence that exposure to RCS dust may also cause kidney disease. Your responsibilities as a PCBU. As a PCBU, you must ensure the health and safety of workers and that others are not put at risk from your work. Before starting work using artificial/engineered stone, you must complete a risk assessment and review your controls.
