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.
ability of health care facilities and safety measures at the site as ways of minimiz-ing occupational health hazards associ-ated with stone quarrying. Materials and Methods This cross-sectional study was con-ducted in stone crushing site located at Umuoghara community in Ezza North Local Government Area of Ebonyi State, Nigeria.

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 various unit operations involved in stone crushing viz., size reduction, size classification and transfer operations have the potential to emit process and fugitive dust. A detailed air pollution survey was conducted at …
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.
Respirable crystalline silica dust generated during stone crushing operations has been linked to chronic lung disease and increased risk of tuberculosis.
Environmental Impact of Stone Crushers. A. Air Pollution 1. Dust Emissions During Crushing Operations The crushing of rocks generates significant amounts of dust particles, which can be released ...
Mineral Processing Operations – Crushing & Grinding Problem: Respirable crystalline silica dust exposure has long been known to be a serious health threat to workers in many industries and occupations.
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 …
Daily exposure to stone dust for 8-10 hours without protective equipment is a major reason for these health problems. ... stone crushing, ... Health effects were described in the previou s section ...
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 …
Environmental exposure to dust from quarrying activities could pose health dangers to the population living nearby. This study aimed to investigate the health effects of dust exposure on people living close to quarry sites and compared them with those ...
Stone crushing and quarrying activities have a significant impact on both human health and environmental quality. The current study was carried out to evaluate the environmental impacts of ...
The study concluded that generation of PM 2.5-sized particles may impose serious respiratory health effects over the workers engaged in mining, crushing, and transportation of sandstone. Apart from it, population residing downwind of the mining area is particularly vulnerable to the pulmonary effects due to inhalation of dust.
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).
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.
Other Hazards: In addition to the hazards associated with RCS, and hazards that may be the subject of the programmed or unprogrammed inspection, other hazards (e.g., crushing hazards from unsecured slabs, guarding of grinders, exposure to resins, adhesives and pigments) that may be encountered in engineered stone fabrication 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 …
The data on various health effects obtained from the current survey among the stone crushing workers and the population inhabiting in and around crushing sites. The activities such as digging, blasting, unloading, crushing loading release dust particles of variable sizes into immediate atmosphere.
The various unit operations involved in stone crushing viz., size reduction, size classification and transfer operations have the potential to emit process and fugitive dust. A detailed air pollution survey was conducted at Pammal, 26 …
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 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.
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.
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 …
Quarry dust control measures are not implemented, and quarry workers are exposed to dust that increase their risk of respiratory diseases. The study was done in 2 …
Understanding the particulate size distribution, chemical composition, and toxicity of airborne dust particles is essential for evaluating health risks and …
