We provide safety critical medical assessments to help employers manage risk and meet workplace health and safety requirements.
On-Site Assessments Available

A Safety Critical medical is an occupational health assessment used by employers to confirm that employees in safety-sensitive roles are medically fit to work without posing risk to themselves or others.
Safety Critical medicals are required for roles where impaired health could increase workplace risk, including operating machinery, working at height, confined space work, and driving specialist vehicles.
Yes. Depending on workforce size and requirements, Safety Critical medicals can be arranged at clinic locations or delivered on-site.
Each Safety Critical medical assessment may vary depending on role and industry, but typically includes:
Medical History Review
We review medical history, current health conditions, and ongoing treatment to identify factors that may affect safe task performance.
Blood Pressure & Pulse
We measure blood pressure and pulse to assess cardiovascular suitability for safety-sensitive duties.
Vision Assessment
We assess distance vision, peripheral vision, and colour vision where required for the role.
Hearing Test (Audiometry)
We assess hearing ability to confirm awareness of alarms, warnings, and environmental cues.
Height, Weight & BMI
We record height, weight, and BMI as part of an overall fitness assessment.
Urinalysis
We carry out urinalysis screening where relevant to identify indicators requiring further review.
Mobility & General Fitness
We assess balance, coordination, and general movement to confirm physical capability for high-risk tasks.
Additional assessments (such as respiratory testing or drug and alcohol screening) can be included where required by site rules, industry standards, or employer policy.
