Health monitoring checker

Choose what workers are exposed to and answer a few questions to see whether health monitoring is required, what it involves and, for lead, when the next blood test is due.

Victoria and Western Australia have their own Acts; the tool switches to them.

Is it ongoing work using, handling, generating or storing the chemical?
Is there a significant risk to workers’ health from exposure?

Consider how much, how often and how long workers are exposed, and how well the controls work.

Health monitoring

On your answers

Check: health monitoring may be required

Isocyanates is listed in Schedule 14. Monitoring is required for ongoing work with it where there is a significant risk to the worker’s health from exposure.

What it involves

  • The type of monitoring set against the chemical in the schedule, usually a medical and occupational history, a physical examination and, for some chemicals, biological testing.

Your duties

  • The PCBU pays for it (r 372). It is carried out or supervised by a registered medical practitioner with experience in health monitoring, chosen after consulting the worker (r 371).
  • Tell workers about the health monitoring before they start the work (r 369).
  • Keep health monitoring reports confidential for at least 30 years (r 378).

Source: r 368–378 and Schedule 14 of the Work Health and Safety Regulation 2025 (NSW).

How this works

Chemicals: r 368 of the WHS Regulations requires health monitoring for ongoing work with a Schedule 14 chemical where there is a significant risk to health, and for other hazardous chemicals where there is also a valid way to test for their effects. Victoria uses r 169 and Schedule 9, which lists the same chemicals.

Lead: lead risk work (r 394) needs monitoring before starting and a month after, then biological monitoring at intervals set by the last blood lead result (r 407), with removal from the work at 30 µg/dL, or 10 µg/dL for a female of reproductive capacity (r 415). Victoria’s levels are the same.

Asbestos: r 435 covers licensed removal work and other ongoing asbestos work with a risk of exposure. Unsure answers give “check”, never “required”.

Questions

Which chemicals need health monitoring?

Schedule 14 of the WHS Regulations lists 15: acrylonitrile, inorganic arsenic, benzene, cadmium, inorganic chromium, creosote, crystalline silica, isocyanates, inorganic mercury, MOCA, organophosphate pesticides, pentachlorophenol, PAHs, thallium and vinyl chloride. Monitoring is required for ongoing work with them where there is a significant risk to health. Lead and asbestos have their own rules.

Who pays for health monitoring?

The business. It must be carried out by, or under the supervision of, a registered medical practitioner with experience in health monitoring, and the worker is consulted on the choice of doctor.

How often are lead workers tested?

Before starting lead risk work and a month after, then based on the last result: every 6 months below 10 µg/dL, every 3 months from 10 to under 20, and every 6 weeks at 20 or more. For a female of reproductive capacity: every 3 months below 5 µg/dL and every 6 weeks at 5 or more.

How long must health monitoring records be kept?

At least 30 years, as a confidential record. In Victoria, 30 years unless WorkSafe Victoria sets a different period.
