In industries where safety and compliance are paramount, confined space entry is a high-risk task requiring rigorous health and safety protocols.
One often-overlooked yet essential aspect of assessing suitability for such environments is the bi-deltoid shoulder measurement.
At Pathways Occupational Health, we deliver comprehensive assessments that include this key measurement to ensure both legal compliance and employee safety.
But what exactly is the bi-deltoid measurement, and why does it matter so much in confined space working?
Let’s break it down.
What Is a Bi-Deltoid Shoulder Measurement?
The bi-deltoid shoulder measurement refers to the maximum horizontal width across the shoulders, specifically from the outermost edge of the deltoid muscles (shoulder caps) on each arm.
It provides an accurate representation of the body’s widest point when moving through narrow or restricted areas.
This assessment is mandatory for all helicopter passengers travelling to the UK sector of offshore installations
This measurement is critical in confined space medicals, particularly in industries like:
- Offshore oil & gas
- Utilities
- Manufacturing
- Construction
- Rail & transport
Why Is the Bi-Deltoid Measurement Important for Confined Spaces?
Ensures Safe Access and Egress
In confined spaces, workers often have to enter through tight manholes, ducts, or crawlspaces.
Measuring shoulder width ensures that employees can safely enter, manoeuvre within, and exit these spaces without risking entrapment or injury.
Supports Rescue Planning
In emergency scenarios, safe and efficient extraction is essential. Knowing an employee’s bi-deltoid width helps emergency response teams understand who can safely be rescued using existing equipment and routes.
Prevents Equipment Complications
Workers in confined spaces often carry essential safety gear like breathing apparatus, harnesses, and protective clothing. These can add bulk to the shoulders. If shoulder width is already near the maximum allowable clearance, adding gear could make movement hazardous or impossible.
Supports Regulatory Compliance
Bi-deltoid measurement is a standard part of confined space medicals, helping organisations meet HSE and COSHH safety requirements. It contributes to a full physical capability assessment, ensuring individuals are fit for the physical demands of the role.
Reduces Risk of Musculoskeletal Injury
Tight spaces increase strain on the neck, back, and shoulders. Understanding shoulder breadth helps assess the biomechanical risks involved, allowing for preventative care and ergonomic planning.
How Is Bi-Deltoid Shoulder Width Measured?
At Pathways Occupational Health, this measurement is taken using a specialised anthropometric calliper or a tape method, with arms relaxed and hanging naturally by the side.
We follow industry-standard protocols to ensure precision and consistency, as even small miscalculations could result in safety issues when accessing confined environments.
What Does a Confined Space Medical Include?
When undergoing a confined space medical with Pathways, employees receive a comprehensive assessment that includes:
- Bi-deltoid shoulder measurement
- Lung function testing (spirometry)
- Blood pressure monitoring
- Audiometry (hearing test)
- Vision screening
- Musculoskeletal and mobility assessment
- Medical questionnaire reviewed by an HSE-approved physician
This holistic approach ensures that only those physically fit and structurally capable are cleared to work in confined environments, significantly reducing risk to health and safety.
Who Needs a Bi-Deltoid Shoulder Measurement?
This measurement is essential for:
- Confined space entrants and rescue team members
- Workers in tanks, silos, tunnels, pipelines, or other restricted environments
- Contractors operating in utilities or infrastructure
- Employees are required to wear full-body PPE in tight spaces
Anyone working in physically restrictive environments, where clearance is limited, will require a Bi-Deltoid Shoulder Measurement.
