Tree-climbing operations must only be performed by people with suitable training, experience and expertise, holding a Certificate of Competence relevant to the task they are performing. It is important to note that a Certificate of Competence is not a measure of experience. The inexperienced must be adequately supervised.
Planning and preparation
- Discuss and plan the job beforehand, prepare a risk assessment and emergency contingencies.
- Remember that the job is a team effort, ground staff should support and monitor the climber at all times.
- If observations are made that cause concern, notify the climber, using the agreed system of communication.
Pre-work checks
- components connected to the climber (climbing ropes, strops) are placed in a 'safe position' away from the risks of entanglement or damage.
- Check for correct positioning of any rigging or lowering systems that may be in use.
- Be vigilant throughout all aspects of the operation.
Anchor points
When sectional felling ('topping down') stems a minimum of 2 attachment or anchor points should be used. There is useful advice on Anchor points on the Aboricultural Association website.
Climbing system and associated equipment
There is a wide range of equipment available which can improve the efficiency of tree-climbing operations. However, if new components are added to a climbing system, the climber must be fully familiar with their correct use and application.
Aerial rescue provision
There must be a second person available equipped, trained and capable of performing an aerial rescue in the event of an emergency.
General observations
Remember that accidents do not only happen to the inexperienced, the time served professional is also vulnerable. Adherence to the key fundamentals learned in training (and highlighted in industry publications) will significantly reduce the risks of accidents.
