    • whenever there are changes in working conditions that affect such exposure;
    • when applicable reference values are exceeded;
    • when the results of health surveillance so justify;
    • where scientific research in this area has been carried out.

The ACT and the inspection services of the Ministry of Health are responsible for monitoring compliance with the rules on the protection of workers' safety and health against the risks of exposure to biological agents at work.
