(1) Every recruited worker shall be medically examined under section 8 of this Act.
(2) Where a worker has been recruited for employment at a distance from the place of recruiting or has been recruited for employment outside Nigeria, the medical examination shall take place as near as may be convenient to the place of recruiting or, in the case of workers recruited for employment outside Nigeria, at the last place of departure from Nigeria.
(3) The Minister may empower an authorized labour officer before whom recruited workers are brought under section 33 or 39 of this Act to permit the departure prior to medical examination of any such worker in whose case the officer is satisfied that-
(a) it was and is impossible for the medical examination to take place near to the place of recruiting or at the place of departure;
(b) the worker appears fit for the journey and the prospective employment; and
(c) the worker will be medically examined on arrival at the place of employment or as soon as possible thereafter.
(4) The Minister may in his discretion (and particularly when the journey of any recruited workers is of such a duration and takes place under such conditions that the health of the workers is likely to be affected) require any recruited workers to be examined both before departure and after arrival at the place of employment.
(5) The Minister shall ensure that all necessary measures are taken for the acclimatization and adaptation of recruited workers and for their immunization against disease, and may issue such directions in that behalf as he may think fit, either generally or in respect of any particular recruiting operation.
