What is a Safety Critical Medical?
A safety critical medical is an occupational health assessment used to determine whether an employee is medically fit to carry out work where their health could affect their own safety or the safety of others.
These assessments are also commonly referred to as fit to work medicals or fitness-for-task medicals. In sectors such as construction, they may also be requested as plant operator medicals, particularly for employees operating heavy machinery or equipment.
The assessment considers whether an employee's health could affect their ability to carry out their role safely and whether any further assessment, advice or workplace recommendations may be required.
Assess an employee's medical fitness for safety-critical work
Identify health conditions that could affect safe working
Make informed fitness-for-work decisions
Identify where further assessment, restrictions or recommendations may be appropriate

Why are Safety Critical Medicals important?
Employees in safety-critical roles may operate machinery or vehicles, work at height, or carry out other activities where their health could affect their own safety or the safety of others.
Employers have a legal duty to manage workplace health and safety risks and ensure employees are medically fit to carry out their work safely. Depending on the role, workplace risks and industry requirements, a medical assessment can help employers demonstrate that fitness for safety-critical duties has been appropriately considered.
