Lantra Awards Level 3 Award in Utility Arboriculture - Arboricultural Activities

LANTRA-AWARDS

vocational

This element focuses on the safe and effective pruning of trees adjacent to overhead power lines using a mobile elevated work platform (MEWP). Learners must master pre-work preparation, precise communication with ground staff, and strict adherence to industry regulations regarding live and dead working. The practical application ensures trees are maintained to statutory clearance distances, minimising the risk of power outages and ensuring the safety of the operative and public.

What You Need to Demonstrate

Key skills and knowledge for this topic

Award credit for demonstrating a thorough pre-use inspection of the MEWP, including emergency lowering controls, and verifying the machine's dielectric properties if applicable.
Look for evidence of clear and unambiguous communication with ground staff, such as using agreed hand signals or radio protocols to coordinate movements near conductors.
Credit should be given when the learner correctly identifies live, dead, or earthed zones and justifies the choice of insulated or non-insulated tools accordingly.
Award marks for executing pruning cuts that meet both arboricultural standards (e.g., BS 3998) and utility clearance specifications without encroaching on proximity distances.
Assess the ability to formulate and explain an emergency rescue plan specific to the MEWP and worksite, including rapid descent procedures and first aid considerations for electric shock.

Examiner Tips

Expert advice for maximising your marks

💡Always reference Lantra Awards’ guidance and relevant industry standards (e.g., HSE GS6, Energy Networks Association documents) in your practical explanations.
💡When describing the pruning operation, emphasize the hierarchy of control measures: elimination of hazard (switching off) before engineering controls (insulated MEWP) and procedural controls (tool selection).
💡Clearly articulate the step-by-step emergency recovery procedure for a MEWP, including the use of ground controls and the priority of calling emergency services if electrical contact occurs.
💡During role-play communication exercises, demonstrate assertiveness and clarity by confirming receiver understanding before transferring any load or moving the platform.

Common Mistakes

Pitfalls to avoid in your exam answers

Learners often underestimate the effect of wind on branch movement, failing to account for dynamic sway which can breach safe approach distances.
A common error is treating all power lines as ‘dead’ after a verbal confirmation without independently verifying isolation and applying earths.
Many candidates neglect to brief ground staff on the exact location of the energized conductor, leading to miscommunication during complex branch removal.
Some operators incorrectly assume the MEWP's fibre glass boom provides total insulation, ignoring the path to earth through wet tyres or outriggers.
