Respirable crystalline silica |
Respirable crystalline silica in the stone benchtop industry. Inhaling respirable crystalline silica dust can lead to serious lung conditions such as silicosis. Find out what your legal responsibilities are and what you can do to minimise exposure to crystalline silica dust at your place of work.
eLCOSH : Controlling Silica Exposures in Construction
Employees produce dusts containing silica when they cut, grind, crush, or drill construction materials such as concrete, masonry, tile and rock. The small particles easily become suspended in the air and, when inhaled, penetrate deep into employees' lungs. Studies show that using a stationary masonry saw to cut bricks, concrete blocks and similar materials can result in hazardous levels of ...

Silica Lawsuit | 2020 Silica Exposure and Silicosis Claims
· Because silica is found in many natural stones and mineral ores, it is common in many manufacturing industries and on construction sites. Those who know about silica dust exposure typically equate it with industries that work with stone materials, sands or soil. However, occupational risk isn't limited to those working with genuine or artificial stone. Workers may need to be careful if they ...
General principles of extraction of metals
Reduction of oxides with more electropositive metals Reduction with coke or carbon monoxide Reduction with molecular hydrogen Electrolytic reduction Note: The reduction with hydrogen is not a widely used because (1) many metals forms their hydrides at elevated reduction temperature, and (ii) the hydrogen used may react explosively
(PDF) Relationship between Silica Dust Exposure and ...
The respiratory problems were found to be directly related to the silica dust exposure, found in the stone crushing industry (Iftikhar et al., 2009). In Nigeria the quarry workers in the stone ...
OSHA's Respirable Crystalline Silica Standard for Construction
Crystalline silica is a common mineral that is found in construction materials such as sand, stone, concrete, brick, and mortar. When workers cut, grind, drill, or crush materials that contain crystalline silica, very small dust particles are created. These tiny particles (known as "respirable" particles) can travel deep into workers' lungs and cause silicosis, an incurable and sometimes ...
Guidance for Controlling Silica Dust from Stone Crushing ...
Guidance for Controlling Silica Dust from Stone Crushing with Water Spray Technology Stone crushing has long been associated with exposure to airborne crystalline silica dust to both workers and those residing in close proximity to these operations. Water spray dust control measures are effective at reducing levels of respirable crystalline silica dust. Studies have reported reductions in the ...

RESPIRABLE CRYSTALLINE SILICA: THE FACTS
Crystalline silica is a natural substance found in stone, rocks, sand and clay, as well as products like bricks, tiles, concrete and some plastic composites. When these materials are worked on, for example by cutting or drilling, the crystalline silica is released as a very fine dust which can be breathed in. This dust is one of the oldest workplace hazards – and it still causes hundreds of ...

Crystalline silica and silicosis | Safe Work Australia
Crystalline silica (silica) is found in sand, stone, concrete and mortar. It is also used to make a variety of products including composite stone used to fabrie kitchen and bathroom benchtops, bricks, tiles and some plastics. When workers cut, crush, drill, polish, saw or grind products that contain silica, dust particles are generated that are small enough to lodge deep in the lungs and ...
Nonoccupational exposure to silica dust
Occupational exposure to silica occurs at workplaces in factories like quartz crushing facilities (silica flour milling), agate, ceramic, slate pencil, glass, stone quarries and mines, etc., Nonoccupational exposure to silica dust can be from industrial sources in the vicinity of the industry as well as nonindustrial sources. Recently, public concern regarding nonoccupational or ambient ...
Experimental Evaluation of Respirable Dust and Crystalline ...
Sheetflowwetting combined with ontool LEV is an effective engineering control for reducing RD exposures during engineered stone edge grinding and blade cutting. On the other hand, addition of LEV to some waterspraywetted tools may reduce the effectiveness of the wet method. Experimental Evaluation of Respirable Dust and Crystalline Silica Controls During Simulated Performance of Stone ...
Nonoccupational exposure to silica dust
Occupational exposure to silica occurs at workplaces in factories like quartz crushing facilities (silica flour milling), agate, ceramic, slate pencil, glass, stone quarries and mines, etc., Nonoccupational exposure to silica dust can be from industrial sources in the vicinity of the industry as well as nonindustrial sources.
Stonemasons: Preventing crystalline silica exposure
If it is not reasonably practicable to eliminate a risk associated with crystalline silica, the employer must reduce the risk so far as is reasonably practicable by: substitution (for example instead of using engineered stone, which can be up to 95% silica, use natural stone, which has a much lower silica content) isolation (for example using automation) engineering controls (see below) or; a ...
