Carry out rope assisted felling of a tree up to 380mm diameter, in proximity to overhead powerlines, using a chainsaw
This unit covers rope-assisted felling of trees up to 380mm diameter near overhead powerlines. It includes health and safety, risk assessment, safe working procedures, and practical felling techniques.
Assessment criteria
Topic Overview
The Lantra Awards Level 3 Award in Utility Arboriculture - Arboricultural Activities is a specialised qualification for arborists working near overhead power lines and other utility infrastructure. It covers the safe and effective management of trees in proximity to electrical conductors, focusing on risk assessment, work methods, and legal compliance. This award is essential for professionals seeking to advance their careers in utility arboriculture, as it bridges practical tree work with the stringent safety requirements of the utility sector.
The qualification emphasises the unique hazards associated with working near live electrical equipment, including the risks of electrocution, arcing, and induced voltages. Students learn to identify tree species, assess their condition, and plan removal or pruning operations that minimise danger to both workers and the public. The course also covers relevant legislation, such as the Health and Safety at Work Act and Electricity at Work Regulations, ensuring that arborists can operate legally and responsibly within utility corridors.
Mastery of this award demonstrates a high level of competence in utility arboriculture, making candidates valuable assets to utility companies, tree surgery firms, and local authorities. It fits into the wider subject of Horticulture & Land Management by addressing the critical intersection of arboriculture and infrastructure management, promoting sustainable tree care while prioritising public safety and service reliability.
Key Concepts
Core ideas you must understand for this topic
- →Minimum Approach Distances (MADs): The closest distance a person or tool may approach live electrical conductors without additional protective measures. Understanding MADs is critical for preventing electrocution.
- →Risk Assessment for Utility Arboriculture: Identifying hazards such as overhead lines, tree condition, weather, and ground conditions, and implementing control measures like exclusion zones and insulated tools.
- →Tree Biology and Decay: Recognising signs of decay, disease, or structural weakness in trees that could affect their stability during work near power lines.
- →Legislation and Compliance: Knowledge of the Electricity at Work Regulations 1989, Health and Safety at Work Act 1974, and industry guidance (e.g., HSE GS6) to ensure lawful operations.
- →Work Methods: Techniques for tree pruning, felling, and dismantling using rope access, mobile elevated work platforms (MEWPs), or ground-based methods while maintaining safe distances from conductors.
Learning Objectives
What you need to know and understand
- 1. Understand the requirements of health and safety legislation, guidance and industry good practice relating to tree felling operations in proximity to overhead powerlines2. Be able to undertake a site-specific risk assessment3. Understand the safe working procedures for each category of tree.4. Be able to perform a pre-work inspection5. Understand the application of equipment for tree felling operations6. Understand need for accurate felling direction and importance of using appropriate techniques7.

Assessment Criteria
Key criteria assessors look for in your portfolio
- Understand health and safety legislation for tree felling near powerlines.
- Undertake a site-specific risk assessment.
- Set up and perform an assisted fell system correctly.
- Demonstrate accurate felling direction using appropriate techniques.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always follow the industry good practice guidelines.
- 💡Practise risk assessment on different sites.
- 💡Ensure clear communication with team members.
- 💡When answering questions on risk assessment, always use the hierarchy of controls: elimination, substitution, engineering controls, administrative controls, and PPE. Examiners look for systematic thinking.
- 💡Be precise with MADs: memorise the standard distances for different voltage levels (e.g., 3m for up to 132kV, 6m for 275kV, 7m for 400kV). Quoting exact figures shows depth of knowledge.
- 💡In practical assessments, demonstrate clear communication with your team and the utility company. Show that you can coordinate effectively, especially when requesting a line outage or using a 'live-line' permit.
Common Mistakes
Common errors to avoid in your coursework
- Underestimating the risks of overhead powerlines.
- Incorrectly setting up the assisted fell system.
- Failing to check equipment before use.
- Misconception: 'If the power line is insulated, you can touch it safely.' Correction: Insulation on overhead lines can degrade or be damaged; always assume conductors are live and maintain MADs unless a utility company confirms de-energisation.
- Misconception: 'A tree that is not touching the line is safe to work on.' Correction: Trees can conduct electricity through moisture or sap, and induced voltages can occur from nearby lines. Always assess the entire work zone for electrical hazards.
- Misconception: 'Risk assessment is just paperwork and slows down the job.' Correction: A thorough risk assessment is a legal requirement and a practical tool to identify hazards, prevent accidents, and ensure efficient, safe work.
