Where health surveillance is carried out on the employer's premises, suitable facilities should be provided. This includes a room that is clean, warm, well ventilated, having a washbasin with provision made for privacy. A suitable waiting area should be provided.
Medical surveillance should be carried out under the supervision of a qualified occupational health nurse or medical practitioner familiar with the aims of health surveillance and the process you work with.
It should take place when you start work and then at least every 12 months, and more often if the medical adviser requires it. Some of the work may be undertaken by a qualified occupational health nursed under the supervision of a doctor.
