Construction work can be demanding. Workers may operate machinery, work at height, lift heavy materials or work near moving vehicles. A sudden health problem in these settings can put the worker and others at risk.
A Safety Critical Medical checks whether a worker is medically fit for a safety-sensitive role. Many construction sites, employers and contractors ask for this before work starts.
What Is a Safety Critical Medical?
A Safety Critical Medical is an occupational health assessment. It is used for workers whose health could affect safety at work.
The assessment does not simply look for illness. It looks at whether the worker can safely do their job. This is especially important in construction, rail, highways, utilities, engineering and industrial work.
For example, a worker who has blackouts, poor vision or uncontrolled blood pressure may be at higher risk when working at height or operating machinery. The medical helps identify these risks early.

Who Needs a Safety Critical Medical?
Safety Critical Medicals are often needed when a job involves risk. This may include employees, subcontractors, agency workers and self-employed workers.
Construction Workers
Labourers, groundworkers, demolition workers, site operatives and civil engineering workers.
Plant Operators
Workers using excavators, telehandlers, forklifts, cranes, site vehicles or heavy machinery.
Working at Height
Scaffolders, roof workers, steel erectors and workers using ladders or platforms.
Hazardous Work
Workers exposed to confined spaces, dust, fumes, noise or physically demanding tasks.
Employers may also ask for a Safety Critical Medical for driving, lone working, night work, heavy manual handling or safety supervision.
Why Are Safety Critical Medicals Important?
Construction sites can be dangerous. Workers often operate machinery, work at height and move heavy materials. Some health problems can increase the risk of accidents.
These include blackouts, uncontrolled high blood pressure, poor vision, hearing loss, breathing problems and poorly controlled diabetes.
A Safety Critical Medical helps identify these problems early. It also gives employers evidence that a worker has been assessed for safety-sensitive duties.
