Persons suffering from diseases shall not engage in dust operations.

Those suffering from one of the following diseases shall not engage in dust operations:

(1) Active pulmonary tuberculosis and extrapulmonary tuberculosis.

(2) Severe upper respiratory tract or bronchial diseases.

(3) Pulmonary or pleural lesions that significantly affect lung function.

(4) cardiovascular organic diseases.

(5) Other diseases that are medically identified as unsuitable for dust operation.

How to protect:

Some dust operations can cause pneumoconiosis, for example, silica dust can cause silicosis, coal dust can cause coal workers' pneumoconiosis, and asbestos dust can cause asbestosis. Occupational contraindications and lung injury degree of dust exposure can be found through occupational health monitoring.

The object of inspection is the newly hired personnel who intend to be exposed to productive dust and those who are transferred to other posts. The occupational contraindications that are not suitable for dust work are: active tuberculosis; Chronic obstructive pulmonary disease; Chronic interstitial lung disease; And diseases with impaired lung function. ? Examination content: symptom inquiry, focusing on the history of respiratory and cardiovascular diseases, smoking history and symptoms such as cough, expectoration, wheezing, chest pain, dyspnea and shortness of breath; Physical examination, mainly routine examination of internal medicine, focuses on respiratory system and cardiovascular system. ? Laboratory tests and other necessary items: blood routine, urine routine, electrocardiogram, serum ALT, anteroposterior X-ray chest film or digital radiography (DR chest film), lung function.

The object of inspection is all personnel exposed to productive dust. First, check whether there is pneumoconiosis; The second is to check whether there are occupational contraindications, and the content is the same as before taking up the post. ? Examination content: symptom inquiry, focusing on cough, expectoration, chest pain, dyspnea, wheezing, hemoptysis and other symptoms; Physical examination, routine examination of internal medicine, focusing on respiratory system and cardiovascular system. ? Laboratory and other examinations: the required items include posterior and anterior X-ray high kV chest film or digital photography chest film (DR chest film), electrocardiogram and lung function; The selected items include blood routine, urine routine and serum ALT. ? Health inspection cycle: different dust inspection cycles are different. Silica dust and asbestos dust are classified as Grade I, 2 years 1 time; Grade II and above, 1 year, 1 time. Coal dust operation is classified as Grade I, 3 years 1 time; Grade II and above, 2 years 1 time. The X-ray chest films of silica dust, coal dust and asbestos dust show that the observed objects have health examination/kloc-0 times a year, and the observation lasts for 5 years. If the diagnosis cannot be made within 5 years, the silica dust and asbestos dust will be rated as Grade I, and within 2 years 1 time; Grade II and above, 1 year 1 time. Coal dust operation is classified as Grade I, 3 years 1 time; Grade II and above, 2 years 1 time. In principle, patients with silicosis and asbestosis should be examined every year 1 time, coal workers' pneumoconiosis every 1 ~ 2 years 1 time, or at any time according to the condition.

The objects of occupational health examination at the time of resignation are resigned persons, retirees and internal transfer personnel who are exposed to occupational hazards; The examination time is before leaving the post. The last physical examination during the on-the-job period is within 90 days before leaving the job, which can be regarded as a full-time physical examination. The target disease is pneumoconiosis, and the examination content is the same as during the on-the-job period.
