A Safety Critical Assessment—also known as a Safety Critical Medical—is a specialist occupational health evaluation that confirms whether an individual is fit to perform a safety-critical role without endangering themselves, co-workers, or the public.
Unlike a routine health check, these assessments are role-specific and focus on the essential physical and mental capabilities required to carry out high-risk jobs safely.
The core principle is simple: if a sudden health issue such as loss of consciousness, poor vision, hearing impairment, or reduced lung function occurs in a safety-critical role, it could result in a serious accident, injury, or even fatality. By identifying risks early, employers can protect workers, reduce incidents, and remain compliant with industry and HSE requirements.
Our Safety Critical Medicals confirm employees are fit to perform high-risk tasks safely. We tailor each assessment to role and risk profile—helping you prevent incidents, reduce downtime and meet compliance obligations.
Typical roles include construction and civil engineering, rail and utilities, plant and machinery operators, maintenance technicians, night workers, drivers, and those working at height or in confined spaces.
Clinical review & questionnaire
Vision testing (including colour vision where role-specific)
Hearing (audiometry)
Blood pressure, BMI & general health checks
Urinalysis (where indicated)
Musculoskeletal & neurological assessment
Role-specific add-ons (e.g., working at height, confined spaces, night worker assessments)
Choose onsite clinics, Mobile Medical Units, or appointments via our national clinic network. We plan schedules around shifts to maximise attendance and minimise disruption.
You receive a clear fitness outcome and guidance on any restrictions or adjustments. Certificates are typically valid for 1–2 years, with shorter intervals where risks or findings require earlier review.
Share your roles, headcount and locations. We’ll recommend a schedule and provide a clear quote.
