The Health and Safety at Work Act 1974


What are Safety Critical Worker Medicals?

Safety Critical medicals are in-depth medicals designed to ensure anyone who may be undertaking safety-critical tasks is fit to do so to ensure the safety of themselves and others.


Why do you need them?

Under current health and safety legislation, employers have a duty of care to prevent ill-health or injury of their workers. This is particularly relevant to those carrying out safety-critical tasks and those around them.

It is important that safety critical workers are not suffering from medical conditions or undergoing any medical treatment which is likely to cause sudden loss of consciousness or incapacity, impairment of awareness, concentration, balance or coordination or significant limitation of mobility.


What is Safety Critical Work?

The term ‘Safety Critical Work’ is defined as:

“Any work where the ill health of an individual may compromise their ability to undertake a task defined as safety-critical, thereby posing a significant risk to the health and safety of others.”

How long does the medical take?

The time taken for the Medical varies, depending on the requirements of the job involved. A standard medical can take up to 60 minutes.


How often do I have a medical?

  • 55-65           =   Two years
