Use of chainsaws and other equipment
Chainsaw Operations
- Chainsaws are the primary tool for tree cutting operations, particularly for felling, limbing, and bucking tasks.
- The engine’s power, chain speed, and chain sharpness determine a chainsaw’s cutting capacity.
- Routine maintenance like sharpening, tensioning, and lubricating the chain as well as cleaning the air filter promote efficient chainsaw functioning.
- Importance of proper starting procedures, which typically involve engaging the chain brake, placing the saw on the ground, and pulling the starter handle.
- Kickback: Dangerous chainsaw behaviour caused by the upper tip of the guide bar hitting an object, increasing risk of injury.
- Avoiding kickback through correct handling techniques like holding the saw close to the body and ensuring firm grip on handles.
- Two-handed operation is preferable to maintain better control and balance.
Other Tree Cutting Equipment
- Tree felling wedges, plastic or aluminium tools used during back cuts to control tree fall direction. Especially useful in preventing the tree from “sitting back” on the saw.
- Axes and hatchets, though older tools, still have their use in tree cutting operations for tasks like hewing and splitting.
- Pole pruners and pruning saws for reaching overhead branches during aerial operations.
- Utility of ropes and rigging equipment for controlling limbs and sections of the tree during dismantling operations.
- Wood chippers for efficiently reducing tree limbs and trunks into woodchips.
Personal Protective Equipment (PPE)
- Wearing appropriate PPE is vital to protect from potential injuries.
- Helmet with face shield and ear protection to guard against falling branches, flying wood chips, and loud saw noise.
- Safety glasses for extra eye protection.
- Chainsaw protective trousers and boots to protect against accidental cuts.
- Cut-resistant gloves to offer hand protection.
- Using reflective clothes for better visibility and safety in busy or low light environments.
Safe Working Practices
- Always maintaining a safe distance from the operating chainsaw and falling trees.
- Checking for dead branches or hung-up trees that could fall during operations.
- Understanding the importance of escape routes being clear of obstacles and known to all members involved in the operation.
- Conducting an environmental risk assessment, taking into account factors like wind direction, slope, and trunk lean.
