Confined Space Medicals

Working in enclosed or poorly ventilated environments can pose serious health and safety risks. A Confined Space Medical ensures your employees are fit to work safely and able to exit quickly in an emergency.

What Counts as a Confined Space?

A confined space is any enclosed area where dangerous substances or conditions could cause injury or death. Examples include:
Storage tanks, silos, sewers, and drains
Ductwork, vats, or reaction vessels
Combustion chambers and unventilated rooms

Key Risks

Working in confined spaces carries hazards such as:
Low oxygen from natural reactions
Toxic gases or fumes from leaks or poor ventilation
Flooding or engulfment by liquids or solids
High temperatures leading to heat stress
Dust buildup, fires, or explosions
Restricted access that delays rescue

Legal Responsibilities

Under the Management of Health and Safety at Work Regulations, employers must assess and control risks in confined spaces to ensure worker safety.

How We Help

At Essential Medicals, our Confined Space Medicals assess both environmental risk and employee fitness through:
Health questionnaire and full medical review
Height, weight, BMI, and blood pressure checks
Vision, lung function, and hearing tests
Our clinicians ensure every worker meets the required standard to perform safely in confined environments.

Crane and Forklift Medicals

Operating cranes or forklifts requires focus, coordination, and good overall health. Our Crane and Forklift Medicals ensure drivers are fit to operate safely, meeting both HSE and DVLA Group 2 standards where required.

Who Needs a Crane or Forklift Medical?

Crane operators on public roads require a Category C1 licence and must complete a C1 driver medical.
Forklift and crane drivers on private premises are not legally required to have a specific medical, but HSE guidance recommends a fitness certificate to Group 2 standards. This demonstrates that the individual is medically fit to work at height, at night, and with heavy goods.

Book Your Appointment

We offer flexible appointments, including evenings and weekends, to fit around your schedule.
