What roles require safety-critical medical examinations
Safety-critical work includes tasks where a worker’s ill health can cause a risk to the worker, co-workers, the public, the plant, or the environment.
The employer determines what is safety-critical work after a risk assessment. However, the following roles usually require safety-critical medical examinations:
Certificate of Fitness for Safety-Critical Work
A Safety-Critical Work Certificate is valid for 2 years for healthy workers. Certificate renewal is recommended after a new significant illness or injury.
A Certificate of Temporary Unfitness is issued if a worker requires an up-to-date GP report, medical investigations or treatment (e.g., high blood pressure or unstable diabetes).
A Certificate of Permanent Unfitness is issued for workers with significant permanent impairment (e.g., a permanent vision loss or treatment-resistant epilepsy).
In case of significant health concerns, we may need to contact the worker’s GP (additional fees apply).
If employers require detailed information and advice, we offer a comprehensive occupational health assessment and report, conducted by an occupational health doctor.

Employee’s legal duties
Under the primary legislation, the Health and Safety at Work Act 1974, employers must provide safe workplaces and systems of work. This includes verifying that workers in high-risk roles are physically fit to work safely.
The Management of Health and Safety at Work Regulations 1999 require a suitable and sufficient risk assessment to ensure health and safety.
Under the Common Law, Employers must take reasonable care of their workers and reduce the risk of reasonably foreseeable injuries.
Certain industries have specific guidelines for safety-critical workers. For instance, organisations such as Oil and Energy UK, Energy Institute UK, DVLA, Network Rail, Police, or Fire Service arrange their own medical checks.
In addition, safety-critical workers may require health surveillance, e.g., under noise, ionising radiation, vibration, asbestos or COSHH regulations.

How to get a safety-critical medical in Bristol or Chepstow?
You can book a safety-critical medical online.
How often are safety-critical medicals needed?
Safety-critical medicals are typically required every 2 years for healthy workers. Workers with health conditions, such as high blood pressure, may need more frequent checks. It is a good practice to renew the safety-critical medical for workers who develop a significant medical condition.
What happens if I don’t pass my safety-critical medical?
If a significant health issue is found during your safety-critical medical, you may receive a temporary unfitness certificate, requiring further medical evaluation or treatment. In severe conditions, permanent loss of vision or hearing, we may issue a permanent unfitness certificate.
In more complex cases, we offer occupational health assessments to advise on redeployment to adjusted (non-safety-critical) work, temporarily or permanently.
