What is included in a Health Surveillance Medical?


On WorkSafe Western Australia Health Surveillance issued paperwork, the medical typically includes full work history and health questionnaire, a physical examination and specific tests depending on the health effects of the hazard e.g. Spirometry (Lung testing), Chest X-Ray


How often is a Health Surveillance Medical required?


The Health Surveillance Medical is required before the worker commences employment, at regular intervals depending on the substance and at the termination of the employment.


The regular intervals are generally 6 weeks after the initial medical then 6 months later and yearly thereafter.


Our Medical professionals will provide the worker with education about the potential effects of the substance, the importance of PPE and personal hygiene. Workscreen Medical will provide feedback to the employer regarding the effectiveness of control measures based on the health surveillance results and provide explanations to the worker.

If there is evidence of adverse effects due to the substance, Workscreen medical will provide the employer with interventions to take including removal from work.

When required, WorkSafe Western Australia will be notified, and Health Surveillance records are kept for at least 30 years as required by law.
