Topic Synopsis
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.
Key Concepts & Core Principles
- 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.
Exam Tips & Revision Strategies
- Always follow the industry good practice guidelines.
- Practise risk assessment on different sites.
- Ensure clear communication with team members.
Common Misconceptions & Mistakes to Avoid
- Underestimating the risks of overhead powerlines.
- Incorrectly setting up the assisted fell system.
- Failing to check equipment before use.
Examiner Marking Points
- 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.
