Non-occupational 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., Non-occupational exposure to silica dust can be from industrial sources in the vicinity of the industry as well as ...

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 material for …

A reduction in respirable particulate mass following the application of a fine mist of water in the Khurda District of Orissa demonstrated that relatively inexpensive modifications that are available in the local market can be effective at reducing silica exposures. Abstract Respirable crystalline silica dust generated during stone crushing operations has been …

By demonstrating pollution control equipment and educating workers, we hope to reduce exposures to airborne silica in the stone crushing industries in this region.. Additional Documentation. This project has provided additional documentation in a …

A cluster of 50 stone Crushing units located at Pammal, in Suburban Chennai, the capital of Tamil Nadu State, India, is a Source of high levels of dust generation in the vicinity of the crushers ...

Portable crusher plant is designed to provide flexibility and mobility to stone crushing operations. They can be easily transported to different job sites and are ideal for crushing stones in remote areas. Portable crusher plant can be equipped with jaw crushers, impact crushers, or cone crushers, providing versatility in various applications.

The Spiro metric pulmonary function tests (PFT) were studied in stone crusher workers (n = 120) and normal healthy controls (n =120) from the Karad taluka Western region in Maharashtra state.

Expert analysis shows dust from engineered stone poses unique hazards, and there is no evidence that engineered stone with a lower silica content (e.g. 40% or 10%) is safer to work with. There were also concerns that permitting work with lower silica products may encourage greater non-compliance because products may be viewed as …

the lungs, thus increasing the importance for the control of respirable silica dust generated from stone crushing units. Figure 1. Stone crushing operations create large quantities of respirable dust. Workers exposed to respirable silica dust have an increased risk of developing lung diseases such as silicosis or tuberculosis. Engineering Controls

Controlling and minimizing exposure to silica dust requires proper wet dust suppression for rock crushers. Because water has a relatively high surface tension (72 dynes per cm), it …

Several methods for reducing worker exposure to silica dust at crusher locations are provided below: Isolate the facility from the general mine air circuit. Dust generated …

Isolate and ventilate dust. The less silica dust you create or leave floating around in your vicinity, the less you are likely to inhale. Therefore, proper dust reduction and ventilation procedures are also straightforward ways of reducing silica exposure. If, for instance, your job involves cutting concrete blocks, the use of a wet saw (which …

They're made from recycled old structures, reducing the necessity of quarrying and easing landfill space. It's good for the Earth and great to reduce cost since there are savings on throwing out waste and buying new materials. With modern crushing technologies, recycled crushed stone aggregates can match the quality of new ones.

Engineered stone products can contain up to 97 per cent silica. The high amount of silica means that there is a very high risk of workers developing breathing problems and silicosis if they breathe in dust made from these products. The vast majority of silicosis cases identified in recent years are in engineered stone workers.

The exposures measured raise concern for possible acute and chronic silicosis and are known to significantly contribute to TB incidence rates in mining communities, and ongoing efforts to address mercury and other hazards in ASGM should incorporate crystalline silica dust controls. Gold miners exposed to crystalline silica are …

Silica exposure has been implicated with the development of various connective tissue diseases. We report a case of 32-year-old stone crusher who developed silicosis with mixed connective tissue disorder (MCTD) 6 years after exposure to silica. This association of silicosis with MCTD has never been …

Silica, a common component of engineered stone, is a natural mineral found in various materials and used in construction. However, its dust form poses health risks. Engineered stone, surprisingly, can have higher silica levels than natural stone, intensifying these risks. In fact, it may contain as much as 90–97 percent crystalline …
