Division 3 Health examination of workers should be carried out in accordance with the principles and practices of occupational medicine. It should include at least the following measures:

• keeping records of a worker’s medical and occupational history,

• a personal interview,

• a general clinical examination, with particular reference to the chest,

• lung function tests (respiratory flow volumes and rates).

The doctor and/or authority responsible for health surveillance should decide on further examinations, such as sputum cytology tests or a chest X-ray or a tomodensitometry, in the light of the latest occupational health knowledge available.
