What Is a SEQOHS Safety Critical Medical?

A SEQOHS Safety Critical Medical is a comprehensive Fit to Work assessment specifically designed for individuals in high-risk occupations — roles where even a minor health issue could lead to a major incident. These medicals are not just a formality — they are a legal safeguard, protecting both the worker and those around them from the risks associated with poor health on dangerous job sites.

If you work in environments involving working at height, operating plant machinery, operating excavators, cranes, handling hazardous materials, driving HGVs on sites, or performing any task where impaired judgement or physical condition could result in serious injury or fatality, a SEQOHS-compliant Safety Critical Medical is essential — and often mandatory before you can even step foot on site.

The assessment is carried out by qualified occupational health professionals, trained in delivering SEQOHS-accredited medicals in line with the latest HSE and industry guidance. This means your certificate will be recognised by principal contractors, infrastructure bodies (including HS2, Network Rail, and National Highways), and site managers across the UK.

Who Needs a SEQOHS Safety Critical Medical?

A SEQOHS Safety Critical Medical is required for workers in high-risk roles where health can directly impact safety and operational success. If you’re employed in industries like construction, rail, highways, civil engineering, logistics, and utilities, a Fit to Work assessment is not just an added step — it’s a legal and regulatory necessity that ensures safety and compliance.

Roles in these sectors involve hazardous environments and tasks where even slight health impairments can result in catastrophic consequences. Whether you’re operating heavy machinery, driving HGVs, working at heights, or handling dangerous materials, a SEQOHS-compliant medical ensures you meet the strict health standards necessary for safety-critical jobs.

This comprehensive health check guarantees that workers are fit and ready to perform tasks without putting themselves or others at risk. It’s about ensuring that you meet the occupational health standards required for each high-risk industry, from roadwork to railways, construction sites to offshore platforms. Having a valid SEQOHS medical certificate confirms that you’re medically fit to perform your duties and remain compliant with industry regulations.

By undergoing a SEQOHS Safety Critical Medical, you ensure that your health aligns with the demanding needs of your profession, meeting both employer requirements and safety standards. This is especially crucial in environments where health-related risks can lead to accidents, delays, and even fatalities. Whether it’s a construction medical for scaffolders, HS2 medicals for rail workers, or fit-to-work assessments for offshore technicians, a SEQOHS Safety Critical Medical provides peace of mind for both the employee and employer alike, ensuring that safety remains a top priority in every workplace.

You may need a SEQOHS-compliant Safety Critical Medical if you work in any of the following roles:
