Practical fitness-for-work assessments for roles where a health issue could create a serious safety risk. We’ll help you arrange the appropriate medicals around your people, sites and operational needs.
A safety-critical medical considers an employee’s health in relation to the work they do. It can help you understand whether they are fit for specified duties, whether adjustments or restrictions may be appropriate, or whether further information is needed before a decision can be made.
This may include risks arising from loss of consciousness, impaired vision or hearing, reduced mobility, poor balance, respiratory difficulty, cardiovascular conditions, medication effects or other health factors relevant to the role.
It can help employers:
Make informed decisions about safe work allocation.
Identify where temporary restrictions, adjustments or further assessment may be appropriate.
Support workforce planning for high-risk roles.
Demonstrate a structured approach to managing occupational health risks.
Review fitness when there has been a change in role, health, work circumstances or safety concerns.
A safety-critical medical complements risk assessment, training, supervision, safe systems of work and competency management.
Medicals may be appropriate for employees who drive or operate workplace vehicles and plant, work at height, enter confined spaces, or carry out other tasks where sudden incapacity or reduced capability could create serious harm.
Typical examples include:
A safety‑critical medical is a structured assessment carried out by appropriately qualified occupational health clinicians. While the exact content is tailored to the role and risk profile, it will typically include a combination of:
Medical history and health questionnaire
Vision testing (including colour vision where required)
Hearing assessment (audiometry)
Blood pressure and cardiovascular checks
Respiratory assessment (e.g. spirometry, where indicated)
Height, weight and BMI
Where appropriate, additional elements – such as hand‑arm vibration (HAVS) assessments, skin surveillance or night‑worker assessments – can be incorporated to ensure the medical remains aligned to your overall risk assessment.
All our safety‑critical medicals are carried out to DVLA Group 2 standards wherever applicable, and Clarity’s clinicians provide a clear fitness‑for‑work outcome (e.g. fit, fit with restrictions, or unfit) along with practical recommendations to support safe placement and management.
We can arrange health surveillance at your workplace, through mobile medical units or at local clinics. Together, we’ll choose an approach that suits your locations, shift patterns and workforce availability.
Choose the delivery model that works best for your organisation:
Planned health-surveillance sessions at your workplace
Practical delivery for busy, remote or multi-site workforces
Accessible local appointments for employees across the UK
Employers receive an outcome relevant to the employee’s duties—for example
Fit for specified duties.
Fit with recommendations, restrictions or adjustments.
Temporarily unfit pending further information, treatment or review.
Not fit for specified safety-critical duties.
Where appropriate, we’ll set out practical next steps.
Reports focus on the employee’s functional fitness and practical workplace recommendations. They do not provide managers with the employee’s full medical history or confidential clinical records.
There is no single validity period that applies to every safety-critical role.
The appropriate schedule depends on:
Role demands and the consequences of sudden incapacity.
Age, health factors and clinical findings.
Sector, client or contractual standards.
Relevant driving or licensing rules.
Workplace risk assessment and task analysis.
Any significant change in health, medication, role or incident history.
As an example, HSE advises workplace-transport operators should be screened before employment and at five-yearly intervals from age 45, with annual assessment after age 65. Other sectors may require different intervals; construction guidance may, for example, recommend three-yearly periodic examinations with shorter review periods for certain findings or older workers.
We can help you agree a schedule that is clinically appropriate, practical to administer and aligned with your workforce risks.
Whether you are introducing a safety-critical medical programme, reviewing your current provider or responding to a role, client or workforce change, Clarity can help.
Tell us about the work your employees carry out, your locations and your practical requirements. We will guide you through the available options and help you put a programme in place that supports safer work and fits around your operations.
A safety-critical medical is an occupational health assessment that considers whether an individual is medically fit to undertake work where impaired health or sudden incapacity could create a significant risk to themselves, colleagues or the public.
Employees may need a safety-critical medical where their roles involve high-risk work, such as professional driving, workplace transport, plant operation, work at height, confined spaces, construction, utilities, rail, hazardous processes or other duties identified through risk assessment.
Not always. DVLA Group 2 standards apply to bus and lorry drivers and may be used as a benchmark for relevant driving or vehicle-operation roles. Other safety-critical roles should be assessed against the requirements of the job, workplace risk assessment and any applicable sector or client standards.
The assessment is designed around the role and may include medical history, vision, hearing, blood pressure, cardiovascular screening, respiratory assessment, musculoskeletal review, urinalysis and other relevant checks. Not every role needs every assessment element.
A full safety-critical medical usually requires a face-to-face appointment because it may include objective measurements, physical examination and testing. Remote contact may be suitable for pre-assessment information gathering, triage or follow-up where clinically appropriate.
Frequency depends on the role, risks, age, clinical findings and any sector or client standard. For workplace transport operators, HSE advises screening before employment and at five-yearly intervals from age 45, with annual assessments after age 65. Other roles may follow different schedules.
Employers receive an outcome relevant to the employee’s role, such as fit, fit with recommendations or restrictions, temporarily unfit pending review, or not fit for specified duties. Managers receive practical functional advice rather than full confidential medical details.
Yes. Where suitable, assessments can be delivered on site or through a mobile medical unit. Clinic appointments can also be arranged for individual employees or where particular assessment facilities are required.
Yes. Safety-critical medical information is handled under clinical-governance and data-protection arrangements. Employers receive the relevant fitness outcome and workplace recommendations, while confidential clinical details remain protected.
