Section 27-29. X-ray examinations of employees in connection with rock work

Employees who are exposed to dust that puts them at risk of developing pneumoconiosis shall undergo an X-ray examination of the lungs before the work starts. This does not apply to employees who have undergone such an examination in the past five years.
An X-ray examination of the lungs shall also be carried out whenever it is considered necessary. The medical practitioner decides whether this is necessary and the frequency of such examinations based on the employee's health condition and the nature, degree and duration of exposure.
