Fit to work medicals

Safety critical worker medical

OH3 provides the full remit of services to the construction industry to comply with health and safety legislation and promote equality, health and well-being in the workforce.

Our construction industry safety critical worker and fit to work medicals are available for both private individuals wishing to book a medical for themselves as well as larger construction businesses booking medicals for their employees. We can look after the employee health of large multi-site organisations or provide smaller sub-contractors with the services they require in order to work for the larger organisations.

The construction industry is continuing to improve medical standards for site safety. Many large organisations now require their employees and subcontractors employees to undergo a safety critical medical when performing certain types of work on a construction site. OH3 can provide these assessments as well as the necessary fitness certificates.

Book your safety critical medical

A safety critical or fit to work medical is essential when working in potentially hazardous environments and high risk settings. These are roles such as; plant operators, scaffolding worker, road worker (particularly motorways), traffic marshals, slinger, banksman, signallers, employees working at height, mechanical handling equipment workers and fork lift truck drivers as well as tunnel and confined space workers. In these roles a safety critical medical is important as the ill health of a worker can impact their ability to carry out a task safely and could pose a risk to not only the safety of the worker but the safety of their colleagues also.

OH3 is a SEQOHS Accredited clinic, SEQOHS (Safe Effective Quality Occupational Health Service) is run by the Faculty of Occupational Medicine and ensures a high quality occupational health service and rigorous clinical governance in our practice when conducting our SEQOHS safety critical worker and other medicals.

Typically a safety critical worker medical is necessary for private individuals who need to prove that they are fit to work before gaining a contract to work on, for example; a construction site for a larger company, but who are not directly employed by that organisation and remain self-employed during their work in the safety critical setting.

Below you can see what is involved with our safety critical worker and fit to work medicals:

Fit for Task – Safety Critical Worker Medicals consist of the following tests:

– A baseline Safety Critical Worker health questionnaire to establish any current or previous medical/psychological health history
– Blood pressure measurement
– Height, Weight & Body Mass
– Audiometry, hearing test, Industrial standard Audiometry
– Spirometry, full Lung function test
– Visual Acuity, colour vision and peripheral vision screen
– Urinalysis for diabetes or other health issues
– Muscular skeletal assessment
– Mental health assessment


Health questionnaire

An OH3 SEQOHS safety critical medical is initially carried out with a health questionnaire to determine any current or previous medical history. This is to ascertain if there is any evidence of ill health reported and if evidence of ill health is indeed reported, then these conditions should be stable or controlled and should not pose a threat to safety performing safety critical work.


Medical screening

Following on from this initial questionnaire a blood pressure, hearing, respiratory, visual acuity and colour perception, mental health, mobility and coordination assessment will be carried out, with reporting of musculoskeletal or neurological disorders and if requested a drug and alcohol screen (if applicable). In addition to this a check for evidence of over the counter medication that would be likely to cause symptoms that would pose a risk in a safety critical role would also be undertaken.


Further information

The medical will be conducted by one of our OH3 Occupational Health Nurses at our clinic and may be referred onto our Occupational Health Physician if there are doubts about a person’s fitness to carry out safety critical work. It is recommended that safety critical and fit to work medicals are carried out every three years, but reviews can be conducted sooner if directed by the OH Nurse. Consent both to complete the medical and return the fitness certificate, as well as consent for advice about adjustments or restrictions if necessary will also be obtained.

Construction industry medicals for companies

As well as safety critical medicals carried out for private individuals, OH3 can also arrange safety critical and fit to work medicals for companies that require these medicals for their workforce. Employers have a duty of care to safeguard the ill health of their employees under the Health and Safety at Work Act 1974. It is essential that employers determine whether the ill health of an employee could jeopardise their safety and the safety of others whilst at work in a safety critical role. Employers in the construction industry must ensure that their employees do not currently have medical conditions that could result in poor balance and coordination, potential loss of consciousness or impairment of mobility, as this could put themselves and other employees in danger whilst working in a potentially hazardous construction environment.

OH3 provides the full remit of services to the construction industry so they can comply with health and safety legislation and deliver safety critical medical assessments for their employees. We will work closely with your organisation to identify health risks, ensuring that employees remain fit to carry out safety critical tasks. We can look after the employee health of large multi-site organisations or provide smaller sub-contractors with the services they require in order to work for the larger organisations.

The services that we can provide for employers in the construction industry can be tailored to the specific needs of your organisation and can include the medicals below and well as others that may be required:

Confined space medical

Employees working in confined spaces should undergo a medical assessment to ascertain medical fitness for this specific type of safety critical work.

Height worker medicals

Workers such as scaffolders, riggers and other construction workers carrying out tasks at height workers should undergo regular medicals to assess their fitness to work at heights.

Plant operator medicals

These assessments ensure employees operating fork lift trucks or plant machinery are medically fit to operate these safely and that there are no precluding medical conditions or that any precluding medical conditions are well controlled and do not preclude driving.

Employee drug and alcohol testing

We provide employee drug and alcohol testing for those who require safety critical medicals. These are not carried out routinely and are only undertaken at the request of the employer. This service is at additional cost to a standard safety critical medical.
