Topic Synopsis
This subtopic covers the safe operation of chainsaws from mobile elevated work platforms (MEWPs) during arboricultural and forestry tasks. It emphasises pre-work checks, hazard identification, and correct cutting techniques for removing tree limbs and stem sections while working at height. Mastery ensures compliance with industry safety standards and legislation, minimising the risk of accidents and equipment damage.
Key Concepts & Core Principles
- Health and Safety in Land-Based Operations: Understanding and rigorously applying risk assessments, safe working practices, and the correct use of Personal Protective Equipment (PPE) to mitigate hazards associated with machinery, animals, chemicals, and outdoor environments.
- Environmental Stewardship and Sustainability: Recognising the ecological impact of land-based activities and implementing practices that promote biodiversity, conserve natural resources, reduce pollution, and adhere to relevant environmental legislation.
- Practical Skills in Specific Land-Based Areas: Developing competence in fundamental hands-on tasks across chosen pathways, such as safe animal handling and welfare, plant cultivation and care, basic machinery operation and maintenance, or landscape maintenance techniques.
- Teamwork and Communication: Effectively collaborating with colleagues, following instructions precisely, and communicating clearly and respectfully within a land-based working environment to ensure efficient and safe task completion.
- Legislation and Industry Best Practice: Awareness of pertinent laws, regulations, and recognised industry standards governing animal welfare, waste management, chemical storage and use, and general land management practices.
Exam Tips & Revision Strategies
- Always verbalise the checks you are making during the pre-use inspection to demonstrate understanding to the assessor.
- Practice the emergency descent procedure for the MEWP and be prepared to describe it in a theory test.
- Use the correct sequence: plan the cut, communicate to ground staff, then execute with controlled movements.
- Refer to the Approved Code of Practice for MEWPs and PUWER regulations when discussing legislation.
- Keep the chainsaw brake engaged whenever not actively cutting and never carry a running saw on the platform.
Common Misconceptions & Mistakes to Avoid
- Overlooking overhead obstructions (e.g., power lines) during the site risk assessment.
- Failing to secure the chainsaw with a lanyard when not in use, leading to dropped objects.
- Attempting cuts while leaning outside the MEWP guardrails, compromising stability.
- Neglecting to deploy outriggers on soft ground, causing platform instability.
- Cutting without ensuring a clear drop zone or communication with ground crew.
Examiner Marking Points
- Award credit for identifying all relevant hazards and proposing effective control measures in the risk assessment.
- Check that the candidate completes a full pre-use checklist for both the MEWP and chainsaw, noting any defects.
- Confirm the MEWP is positioned with outriggers deployed on stable ground and the work platform is level.
- Require the candidate to demonstrate safe chainsaw starting on the platform, with the chain brake engaged.
- Assess that cuts are made with appropriate notches, back cuts, and hinge wood to direct limb fall safely.
- Look for correct use of work positioning lanyards and fall protection within the MEWP basket.
- Ensure all stem sections are lowered under control, not dropped, unless a designated drop zone is clear.
