Tree surgery on construction sites involves felling, pruning, and removing trees using chainsaws, chippers, and aerial access methods. The work is high risk due to the unpredictable fall direction of branches, the use of sharp cutting equipment, and frequent working at height. This talk covers the hazards specific to tree work and the controls that protect operatives and the wider site team.
Key Hazards
Being struck by falling branches or tree sections during felling operations
Chainsaw contact injuries causing deep lacerations or amputations
Falls from height during climbing or aerial platform tree work
Chipper and shredder entanglement causing severe crushing or amputation injuries
Control Measures
Ensure all tree surgeons hold NPTC or equivalent certification for the chainsaw tasks being carried out.
Establish a drop zone exclusion area equal to at least twice the height of the tree being worked on.
Wear full chainsaw PPE including helmet, visor, hearing protection, chainsaw trousers, and boots.
Inspect chainsaws before each use for chain tension, sharpness, brake function, and fuel system leaks.
Use a banksman to control access to the exclusion zone during all felling and pruning operations.
Plan the felling direction and identify escape routes before making any cuts to the tree.
Use lowering ropes and rigging techniques to control branch descent in confined areas near structures.
Ensure wood chippers have all guards in place and operators are trained in safe feed procedures.
Brief the wider site team on tree work locations and exclusion zones at the daily site briefing.
Remember
All tree surgeons must hold NPTC or equivalent certification for the specific chainsaw tasks
Establish a drop zone exclusion area at least twice the tree height before any felling begins
Full chainsaw PPE including helmet, visor, chainsaw trousers, and boots is mandatory at all times
Plan the felling direction and identify escape routes before making any cuts to the tree
Use lowering ropes and rigging to control branch descent near buildings and structures
Brief the wider site team on tree work locations and exclusion zones at the daily site briefing
