Activities such as abrasive blasting with sand; sawing brick or ... methods for cutting and sawing crystalline silica-containing materials − to reduce workers' exposure to silica dust. Once the full effects of the ...
This could involve developing new tools, processes, or materials that reduce silica exposure. By implementing these strategies, businesses in the engineered stone industry can significantly reduce the health risks associated with silica exposure, ensuring a safer working environment for their employees.
Introduction. Metal and masonry stone, building material, etc play a vital role in urbanisation 1 and today's stone mining and crushing have become the backbone of infrastructure development in India. 2–4 The finished product of stone crushing units in the form of crushed stone, stone chips of various sizes; plays a crucial role as a raw …
(4) Another study of respirable quartz in a large gold mine in South Africa conducted in 2000 reported a mean concentration of 0.051 mg/m3.(5) The results reported here for crystalline silica exposures in above ground rock crushing and processing are similar to the levels reported in small-scale stone crushing operations in India.(23) However ...
Control interventions to reduce exposures in crushing and processing, maintenance processes in fixed plants, and sample preparation in laboratory settings …
Wet methods reduce exposure to silica dust with pneumatic rock drills but are not meant to be used with most electric rotary hammers. Controlling Silica Exposures in Construction While Operating Rotary Hammers Silica is a mineral that is found in stone, soil and sand. It is also found in concrete, brick, mortar and other construction materials.
of reducing respirable dust with water spay misting (Beamer et al., 2005, Ren et al., 2011). However, our pilot was the first to assess the application of this technology to reduce airborne lead and silica exposures in small-scale informal gold mining. 2 Annals of Work Exposures and Health, 2019, Vol. 63, No. 1
Crystalline silica dust is released into the air when miners drill, transport, and crush ore in the effort to extract and process minerals. While some attention is paid to reducing crystalline silica exposures in some large-scale mines in developing countries, ASGM is generally unregulated or illegal and conducted without regards to health and …
Occupations typically exposed to silica dust from this source obviously include the crusher operators and truck drivers, and also the mechanics, cleanup men, and laborers whose tasks require them to work in this area. Description of control: Several methods for reducing worker exposure to silica dust at crusher locations are provided below:
In small stone crusher mills in India with limited resources, water spray controls reduced respirable silica by 80%. 6 Reducing exposures to silica decreases the likelihood of …

Once contracted, there is no cure for silicosis. The goal, therefore, is to limit worker exposure to respirable dust to prevent development of these diseases. What this means to you: Silica refers to the chemical …
The aim of this study is to examine the effects of stone crushing in West Bengal, India, by comparing pulmonary functions of stone crushing workers with those of nonexposed agricultural workers.
It can also cause lung cancer. Cutting, breaking, crushing, drilling, grinding, or blasting concrete or stone releases the dust. As workers breathe in the dust the silica settles in their lungs. For information on protecting workers from harmful exposure to silica dust, see the resources section below, which includes a silica control tool.
