(b) a cardio-respiratory examination, including-
(i) a full size chest x-ray; and
(ii) a lung function test.Periodic Examinations
- 7(4) The employer must ensure that the following periodic examinations are conducted on all employees required to undergo medical surveillance in terms of regulation 11.7(1)-

What must the employer establish and maintain where employees perform work where they are exposed to crystalline silica dust?
11.7 Crystalline silica dust
System of Medical Surveillance
11.7(1) The employer must establish and maintain a system of medical surveillance as contemplated in section 13, for all employees who perform work in any working place where exposure to crystalline silica dust occurs in excess of 10% of OEL for crystalline silica dust as set out in Schedule 22.9(2) (a) and (b)
What does OEL mean?
“Occupational exposure limit” (OEL) means the time weighted average concentration for a 8 hour work day and a 40 hour work week to which nearly all workers may be repeatedly exposed without adverse health effects
What is the limit of exposure for coal dust and asbestos dust before a system of medical surveillance must be established?
Coal dust and Asbestos dust 50% of OEL as set out in Schedule 22.9(2)(a) and (b).
What examinations must be done where employees are exposed to asbestos?
