You will know if you need health monitoring for your job because your persons conducting a business or undertaking (PCBU) will tell you. Your PCBU must tell you if and how they will monitor your health.

Before you start work with a hazardous chemical, your PCBU must tell you how to use, handle, generate or store the chemical. They must tell you:

  • what your health monitoring is
    • for example visiting the doctor, the tests they may do and how often they will do them
  • who your doctor is for your health monitoring
  • what your health monitoring aims to do and its benefits
  • how you should report symptoms of exposure
  • how they will keep records of your health monitoring, and
  • when you should see your health monitoring report and who will give it to you.

At your first appointment, the doctor who will look after your health monitoring should tell you:

  • what might happen if you are exposed to a hazardous chemical
  • what your health monitoring program is
    • for example how often you will be tested and what the tests will be
  • if and when you could be sent to another doctor or specialist
  • how you can spot and report signs of injury, illness or disease, and
  • how your health monitoring results may change your work tasks
    • for example if your health has changed and is either better or worse, your doctor may tell your PCBU that you should stop working with, or can return to working with, a hazardous chemical.


If you will be working with asbestos, you will definitely need health monitoring. Your PCBU must give you information about your health monitoring program before you start work with asbestos.

Lead risk work

If you will be working in a lead risk job, your PCBU must monitor your blood lead levels. You can read more about how this will happen in the guide for PCBUs. Your doctor will also collect information from you about your demographic, medical and occupational history and may do a physical examination.
