Health surveillance is not needed for most workers, but in some work situations and for some exposures/activities it is required by law.
This means having a system to look for early signs of ill health caused by substances and other hazards at work. It includes keeping health records for individuals and may involve routine self-checks, questionnaires or medical examinations to inform the employer (or self-employed person) if corrective action is needed.
Corrective action may involve referral for treatment and/or adaptations to work for individuals affected. More importantly, as an indication that controls may be failing, it should ensure review of risk management and action to prevent further harmful exposures.
