Respirable crystalline silica – very small particles typically at least 100 times smaller than ordinary sand found on beaches or playgrounds – is generated by high-energy operations like cutting, sawing, grinding, drilling and crushing stone, rock, concrete, brick, block and mortar; or when using industrial sand.
Background and objectives The prevalence of occupational injuries among blue-collar workers is higher in the stone-crushing industries due to high-risk and iterant nature of the work. These occupational injuries, in turn, caused workers' ill health, as well as death, which eventually diminish the gross domestic product. We aimed at assessing …

Chronic exposure to dust due to stone quarrying may increase the risk of respiratory problems and impaired lung function-cigarette smokers are at higher risk. BACKGROUND Respiratory problem is one of the major health hazards in dust-exposed workers; it is a major cause of morbidity and mortality all over the world. OBJECTIVE To …
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 …
The stone crusher is one of such industries that exist in the vicinity of almost all major cities and towns throughout the country in all the states because the construction activities go on throughout the country. Stone crusing units also generate dust as byproduct due to mechanical crushing and screening operations (CPCB, 1984).
Dust constitutes one of the major environmental concerns near many aggregate quarries, with crushing often being the most significant source. In this study, dust emissions and dispersion measurements were conducted under real operating conditions at six aggregate quarries in southern Finland.
Stone crushing and associated activities contribute to particulate matter in the surrounding environment and exposure to dust can cause serious respiratory disease, skin, hearing, eye,...
306 Cumulative Effect of Quarry Dust on Respiratory Health of Stone Quarry Workers respiratory problems [3–4]. Particles above 10 microns are filtered in the throat and nose; below 10, as in quarry dust, they may reach the bronchi and cause health issues like bronchitis and other respiratory-related problems [5, 6].
Dust Dust is present in all quarrying and opencast mining operations. While it is often considered to be more of an environmental issue, dust is a potential health risk and it is the nature of the dust that determines the associated risk.
The inhalation of crystalline silica dust constitutes a risk factor for workers' health. Exposed workers can suffer not only certain cardiovascular diseases, but also …
Stone crushing operations emitting silica dust in ... matter (PM10) have adverse effects on human health. Indeed, an increase of 50mg/m3 in particulates levels is shown to induce increase death Supporting this particulate ... Thus air quality is a serious issue in these stone crushing sites where silica dust can affect sinuses, lungs, and ...
A large number of stone quarry workers in this study have experienced disease symptoms associated with silica dust exposure (eye irritation, breathing difficulty, coughing, and common cold) at one point during their working time in the stone quarry …
Size Distribution and Health Effects ... dust cloud produced during the various operations of crushing, ... The occupational environment at the stone crushing sites poses a potential health hazard ...
The host communities on their part must also endeavour to strictly comply with the timing of operations by the companies to reduce and/or avoid accidents and injuries associated with blasting and crushing of the stone products.
Understanding the particulate size distribution, chemical composition, and toxicity of airborne dust particles is essential for evaluating health risks and …
Abstract: The mining and stone crushing activities have considerable effects on the environment quality and human health. The dust emissions contaminate the air and water.
The objective of this research work is to investigate the effects of stone crushing dust on the health of workers of quarry industry at Umuoghara Community in Ezza North Local Government Area of Ebonyi State and to ascertain the …
Respirable crystalline silica dust generated during stone crushing operations has been linked to chronic lung disease and increased risk of tuberculosis.
The total surface area of dust particles are so large that they are more physically, chemically and biologically active than the parent material. Mine dusts are classified based on the size distributions of the particulates and in terms of physiological effects.
The current study was carried out among stone crusher workers to assess the hazards of silica dust and associated effects on the workers health due to their exposure to silica dust. Stone crusher ...
Using crushing machines at construction sites to reduce the size of large rocks, concrete, or construction rubble can generate respirable crystalline silica dust. When inhaled, the …
Operator isolation for crushing machines includes using either an enclosed booth or a remote control station. Operators using crushing machines with enclosed cabs can limit their silica exposure by staying inside the cab during crushing operations. The enclosed cab must: • Be well-sealed and well-ventilated using positive pressure.
