Examiner Tips

Expert advice for maximising your marks

💡When demonstrating aerial pruning, always vocalise your actions and decisions to the assessor to evidence your situational awareness and decision-making.
💡In written knowledge tests, ensure you can quote specific clearance distances from industry guidance such as HSE GS6 or National Grid specifications.
💡Practice seamless rope techniques and tool handling near simulated power lines to build muscle memory and confidence for practical assessments.

Common Mistakes

Pitfalls to avoid in your exam answers

Misjudging conductor sag or sway under wind conditions, leading to inadvertent encroachment of the safety zone.
Failure to establish a clear demarcation zone for live working, confusing dead and live sections during the operation.
Inadequate briefing of ground staff, resulting in miscommunication during the lowering of branches near conductors.
Using uninsulated tools or equipment within the live working zone, increasing electrical risk.
Neglecting to verify that all tree material is clear of lines before removing the climbing line or descending.

Key Terminology

Essential terms to know

1 Be able to undertake the preparation for work activities in proximity to overhead power lines. 2 Be able to understand the requirements of live and dead working on a work site.3 Be able to communicate appropriately with ground staff.4 Understand the specific requirements to be observed when carrying out aerial pruning in proximity to overhead power lines.5 Be able to carry out aerial tree pruning adjacent to power lines.
