Pneumoconiosis can be identified at the provincial disease prevention and control centers and Grade 3A public hospitals where the patient’s employer is located or where he or she resides. Institutions for the identification of pneumoconiosis are required to have the following conditions: approved by the provincial health administrative department, have the conditions for the identification of occupational diseases, and have a certain number of qualified physicians engaged in the identification of occupational diseases. The identification of patients with occupational pneumoconiosis is based on the reliable history of exposure to productive dust, on-site labor hygiene investigation data, and X-ray chest radiographs with qualified technical quality and posterior antecubital films as the main basis for identification. Pneumoconiosis is a type of occupational disease caused by long-term inhalation of dust by the patient, which is retained in the lungs and causes fibrosis of the lungs. People working in mining, machinery manufacturing, metal smelting, building materials industry, etc. are prone to pneumoconiosis.
