Exposure to silica dust is a potent risk factor for TB, as demonstrated in multiple studies, notably among exposed miners and stone crushers.1–3 Silicosis, a lung disease caused by exposure to crystalline silica dust, is one of the most common occupational lung diseases worldwide.4 In addition, silicosis increases the risk of active TB by up to fourfold, and HIV.
Lung disease in crusher workers. 1. . Black Lung Disease Coal Workers' Pnuemoconiosis . Ore crusher.Exposure to heavy dust concentration from stone crushers, may produce several diseases. . involvement of lung and lung function tests in stone quarry workers.
Occupational Lung Diseases Johns Hopkins Medicine. coal workers pneumoconiosis. coal workers pneumoconiosis is caused by inhaling coal dust. also known as black lung disease, the condition, in severe cases, is characterized by scarring on the lungs about 2.8 percent of coal miners have coal workers pneumoconiosis.
Sep 28, 2017 Silicosis is a type of lung disease caused by inhalation of crystalline silica dust and is considered an occupational disease for stone crushers and miners. “Silicosis is mainly caused by quartz dust, and only stones imported from Bhutan have high levels of quartz,” said Rokonuzzaman Rokon, the owner of Jhilik Poultry Feed in Burimari which.
Crusher workers are diagnosed with TB, and according to DOTS report the average life span of a worker is 40-50 years.Rajnarayan R. (2007) andTiwariet. al. (2007)study provide higher prevalence of TB on stone crusher workers. Table-2,3, 4 and 5 shows the distribution of lung function parameters. These tablesrepresent that the workers of older.
The disease was severe in all and rapidly progressive in 3 2 men who had Worked at the crusher for 5 years were totally disabled, the other 2 each with 7 years' exposure died. Unfortunately no autopsies were held. X-ray findings indicated pulmonary fibrosis fibrosis Subject Category Diseases, Disorders, and.
4 cases of severe disabling pulmonary disease are described in men aged between 39 and 51 years who had been employed crushing ferrochrome at the same factory. The similarity of the symptoms, clinical findings, and occupational histories pointed conclusively to an occupational aetiology, although X-ray findings were not always typical. The disease was severe in all and rapidly progressive in 3.
Prevalence rate of respiratory illness or symptoms among stone crusher workers than non-workers. The most common symptom are rhinitis 16.2 , cough 6.8 , shortness of breathlessness 4.1 with wheeze 7 and tightness of chest or.
The results of the present study have shown that the exposure to stone crusher dust and other pollutants in stone crushing factory workers is associated with an impairment of lung function. The direct exposure group showed a statistically significant impairment of lung function as compared to the control. To confirm the above findings, comprehensive studies on large scale are.
Jul 08, 2021 than a third of coal miners and former coal miners suffering from black lung disease struggle with depression, and than one in 10 has recently considered suicide, a new study finds.
Oct 05, 2020 Workers who work further away from the crusher and do not use the required PPE have a higher chance of experiencing adverse health outcomes than those who work closer to the crusher and wear the required PPE. The major disease caused by silica dust inhalation is silicosis, a lung disease. Over time, silica dust can build up in the lungs and.

Methods A combined cross-sectional and cross-shift study was conducted in Dire Dawa cement factory in Ethiopia. 40 exposed production workers from the crusher and packing sections and 20 controls from the guards were included. Personal total dust was measured in the workers' breathing zone and peak expiratory flow (PEF) was measured for all.
Abstract. 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 determine the prevalence of respiratory problems and lung function impairment among quarry workers in Ebonyi State, Nigeria. Methods Respiratory problems and lung function were studied in 403 quarry workers aged.
Lung function in Nigerians because of paucity of such data. Lung function tests were carried out on 56 cement factory workers with mean years of exposure to cement dust of 10.2 5.6 years and on 96 non exposed subjects. The vital capacity (3.7 0.5 versus 4.1.
