The frequency and severity of respiratory disorders among workers exposed to hard metal dust is not well known.The objective of this cross-sectional study is to report the prevalence of respiratory symptoms, functional status, and radiological findings in hard metal-exposed workers in Türkiye.Among 139 workers, 96 were machining workers, and 43 were industrial tool sharpening workers. Radiographic abnormalities compatible with pneumoconiosis were found 39% of the workers and were more in machining workers statistically significant.Also, in machining workers group, percentage of expected values of FVC was lower than industrial tool sharpening workers group. The prevalence of respiratory symptoms was 14.3%, and there was not a statistically significant difference in working groups. The study reveals that pulmonary symptoms, functional abnormalities, and radiological findings are mild. Assuming that reversibility may develop with avoidance from exposure when detected at this stage, early diagnosis of lung damage is essential.
