The Hidden Risk Most Ghanaian Workplaces Still Overlook
Working at just 2 metres? Think again. Discover why a 2m working height can require up to 5.6m fall clearance. Critical safety insight for construction, oil & gas, mining, and ISO 45001 compliance in Ghana and across Africa.
The Dangerous Assumption That Still Causes Real Incidents
A worker is only 2 metres above ground.
Full-body harness?
Lanyard connected?
Supervision in place?
Everything looks safe… until a slip happens.
Despite correct PPE, the worker still strikes the ground or a lower structure.
This is not equipment failure – it is planning failure.
Across Ghana and West Africa, one critical misunderstanding continues to cause preventable incidents:
Low height does NOT mean low risk.
In reality, a simple 2-metre task can require up to 5.6 metres of fall clearance to be truly safe
What Is Fall Clearance?
Fall clearance is the total vertical distance a fall arrest system needs to safely stop a worker before they hit the ground or any obstruction.
It includes:
- Free fall distance (lanyard length)
- Deceleration distance (shock absorber stretch)
- Worker’s body height (D-ring to feet)
- Safety margin
Without this calculation, even a fully compliant system can fail.
A typical fall arrest system requires significantly more clearance than the working height due to lanyard length, deceleration, worker height, and safety margin.
As illustrated above, fall distance is driven by system dynamics , not just the height of the task.
Engineering Breakdown: The 5.6m Explained
A standard energy-absorbing lanyard system typically includes:
- Lanyard Length → 1.8 m
- Deceleration Distance → 1.8 m
- Worker Height → 1.8 m
- Safety Margin → 0.9–1.0 m
Total Required Fall Clearance ≈ 5.6 metres
If your available clearance is less than this, the worker is at risk of ground impact – even with PPE. Even at only 2 metres working height, insufficient clearance means the worker can still hit the ground.
Real-World Scenario (What Happens on Site)
On a typical construction site in Ghana, a worker operates at approximately 2–2.5 metres height using a standard 1.8m lanyard.
The anchor point is positioned at waist level.
During a slip:
- Free fall distance increases
- Shock absorber fully deploys
- Total fall distance exceeds available clearance
The worker strikes a lower level.
This is not PPE failure , it is system design failure.
Common & Costly Mistakes on Ghanaian Sites
- No fall clearance calculation in risk assessments
- Use of standard lanyards in low-clearance environments
- Low or horizontal anchor points
- No rescue plan (suspension trauma risk)
- Over-reliance on PPE instead of engineered solutions
ISO 45001:2018 Perspective
Under ISO 45001:
Clause 6.1 – Risk Assessment
Organisations must identify hazards such as:
- Inadequate fall clearance
- Improper fall protection systems
Clause 8.1 – Operational Control
Requires:
- Fit-for-purpose safety systems
- Effective procedures and controls
Failure here often results in audit nonconformities and real safety exposure

What High-Performing Organisations Do Differently
- Conduct detailed working-at-height risk assessments
- Perform accurate fall clearance calculations
- Use appropriate systems (e.g., SRLs, shorter lanyards)
- Position anchors above workers
- Train teams on real system limitations
- Maintain active rescue plans

Final Thought
Height doesn’t kill — miscalculation does.
A 2-metre job can become fatal when fall clearance is ignored.
