in many work environments. Dusts usually originate from larger pieces of the same material, through one or several mechanical breakdown process es such as grinding, cutting, drilling, crushing, or strong friction between certain materials, such as rocks. It can also be generated from handling powders that contain mineral dust, such as cement mix.

A high level of exposure was found in the construction industry, and significant exposures were also confirmed among miners and foundry workers. Stone quarrying and stone laying were also found to expose workers to high concentrations of crystalline silica. When the dry method of stone quarrying was used, the exposure level was extremely high.

INTRODUCTION. The recent reappearance of coal workers' pneumoconiosis (CWP) 1, 2 and emergence of artificial stone (AS)‐associated silicosis 3, 4, 5 has represented a failure of preventive systems to protect the respiratory health of workers in Australia. This resurgence of pneumoconiosis has occurred at a time when production has increased, mining techniques have been further mechanized ...

The workers in the grinding section namely the mill operators, load carrying workers, and cleaners were the major affected due to the indoor dust. Skin burning was experienced by almost all the workers (%) while grinding chilly, cough and sneezing was another major contributor to the health effects (%) of the workers (see Table 3 ).

A dust risk assessment is a tool used by safety officers to control tasks so that they do not create high levels of construction dust such as silica, wood, and lower toxicity dust. It helps to evaluate if the amount of dust emission magnitude exceeds with the Workplace Exposure Limit (WEL) in construction activities like demolition, earthworks ...

1 Altmetric Metrics Abstract Background and objectives The prevalence of occupational injuries among bluecollar workers is higher in the stonecrushing industries due to highrisk 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.

Thousands of these workers suffer from respiratory conditions and lung diseases, including lung cancer, as a result of direct exposure to silica dust. In 2021, the Health and Safety Executive (HSE) found that 12,000 deaths each year, in the UK, are estimated to be linked to past exposure to dust and chemicals at work. HSE expects the actual ...

Dust hazards in mining. Mining, maintenance or processing activities can result in the release of dust particles into the air. Exposure to dust in mining and quarrying continues to be a major risk to the health of workers. Breathing in dust, such as coal dust, silica dust and other finely powdered materials, can damage the lungs and airways.

The primary cause of most injuries was the workers' failure to use PPE. All major hazardous events were found to possess a highrisk level. Conclusion: Our finding suggests that stone crushing is one of the most hazardous industries and the practitioners must consider the findings when implementing a risk avoidance policy.

The TUC believes that the current standards used for the assessment of dust exposure in the workplace are totally inadequate. There is now clear scientific evidence which suggests that the current UK limits for inhalable and respirable dust of 10 mg/m³ and 4 mg/m³ respectively should be much exposure to silica occurs at workplaces in factories like quartz crushing ...

Silica dust control plan. A silica dust control plan is a practical tool for a PCBU that is informed by a risk assessment. It can help a PCBU identify all potential tasks that may result in exposure, or possible exposure, to silica dust and the control measures to eliminate or minimise that exposure.
