Safety Critical Worker Medicals

With the demise of the original CBH Safety Critical Scheme, MOHS has taken the opportunity to update its process and adjust one or two of the requirements for assessing Safety Critical fitness.

Rather than applying a blanket standard for fitness, as in the original scheme, each individual’s fitness will be assessed against their role. Where possible, adjustments will be suggested to keep those employees in work and on site, with simple advice to their employer on how to keep them safe and/or work around any health deficits.

This does not mean that MOHS will compromise standards. In most cases, there is little if no difference between the original CBH standards and our own. It does mean that we will now take into account the types of work undertaken. Where an employee fails to meet a particular standard, rather than an arbitrary fail, adjustments may be suggested or employee may be passed fit to undertake only certain types of work.

What is the purpose of a safety critical worker (SCW) medical?

Safety Critical Medical assessments were originally intended only for those employees undertaking “Safety Critical roles” such as heavy plant operation, working at heights or working in confined spaces. Unfortunately, this type of assessment is now often applied to all workers entering site, whether their roles are safety critical or not.

The MOHS safety critical medical recognises that not all workers undertake “Safety Critical roles”, but may be passed fit to undertake their own specific tasks and still maintain their own safety and the safety of those around them.

What does the medical involve?

The MOHS Safety Critical Medical Assessment consists of several components. Some of these components are usually reviewed annually, including:

  1. Respiratory Health Assessment
  2. Skin Assessment
  3. Hearing Assessment
  4. HAVS (Hand-Arm-Vibration assessment) where an employee has exposure to hand transmitted vibration 

In addition, there is a medical component that encompasses the following, which is usually reviewed every three years (more often in some cases):

  • blood pressure
  • visual acuity (sight)
  • colour perception
  • psychological and mental health
  • urinalysis (urine test)
  • mobility and coordination (musculoskeletal) checks.

How long does a SCW medical take? 

Due to their wide-ranging scope, SCW medicals usually take around 90 minutes to complete. They can be conducted at our medical centre in West Bromwich or in some cases, at a client’s site. Upon their completion, a fitness certificate will be issued outlining our decision. It may include certain restrictions on types of work or adjustments to role.

In some cases, employees may require review by another practitioner for measurement or treatment, such as their GP or optician. In those cases, fitness will be deferred until such time as the issue has been addressed to the satisfaction of the certifying practitioner.
