A cross-sectional analytical study design was used and data were collected from 411 quarry workers and 411 control for spirometric assessment. Of the 411 quarry workers, 92% had good knowledge of dust as hazard. Three hundred and ninety six (96.4%) had good knowledge of Respiratory Protective Equipment (RPE), 374(91%) used RPE provided by employers and 93.6% used the provided RPE always. Three hundred and eighty eight (95.6%) of quarry workers received training on correct use of RPE. The mean Total Suspended Particle (TSP) in the quarry environment was 5.22±3.38mg\/m3 while TSP in control environment was 0.11±0.08mg\/m3. The mean Particulate Matter of Less than ten micron (PM10) in the quarries was 1.27±0.67mg\/m3 and control environment was 0.02± 0.01mg\/m3. The mean Particulate Matter of less than 2.5 micron (PM2.5) in the quarry was 0.54 ± 0.34mg\/m3 while in the control environment it was 0.02 ± 0.01mg\/m3. The mean Forced Expiratory Volume in one second (FEV1), percentage predicted, for the quarry workers was 79.40 ± 2.73% and control workers were 89.46±31.24%.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786139973385\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9786139973385","offer_id":39455281250397,"sku":"9786139973385","price":61.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/125077c9-ee5a-4f71-859c-5ab7a56d2510.jpg?v=1774509727","url":"https:\/\/shop.autorenwelt.de\/products\/work-related-respiratory-impairment-in-quarry-workers-von-francis-erah","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
