Felling of trees is among the most typical jobs carried out during logging and arboricultural operations. It is a possibly harmful and challenging operation that needs the sawyer (chainsaw operator) to understand trees, be fit, and be trained in tree felling operations.
The most typical technique utilized in felling a tree is a multi-step process that first involves the development of an open-faced notch in the trunk. In effectively performed cuts, the production of the notch places the fixed load of the tree such that the sawyer, through the use of the back cut and the staying hinge, can dependably control the instructions the tree will fall. Nevertheless, mistakes made during felling can result in residential or commercial property damage or major injury/death to the feller or onlookers.
Safe felling operations start with appropriate assessment of the tree and of the conditions in an area 2.0 times the height of the tree to guarantee it is devoid of individuals & property. The next action utilized in felling a tree is making three accurate and tactical cuts. The graphic listed below depicts a “standard” notch, but other notch styles are made use of depending on the circumstances of the cut. Sawyers should make educated decisions regarding the design of notch, along with the depth of each cut to securely and reliably fell trees.
These cuts must be done by a sawyer who has been trained and uses the appropriate personal protective devices like gloves, eye protection, hearing security, head security with face shield, chainsaw chaps, and steel-toed boots. The chainsaw chosen for felling trees must be the appropriate size (bar length) for cutting the subject tree and must be sharp and in great repair work. Having the appropriate equipment like tree felling wedges, taglines, and other tree felling equipment may assist in the safe and efficient felling of trees.
The primary step in felling a tree is for the sawyer to search for a straight tree and has an equivalent size diameter that is without bulges or irregular architecture. If the tree is leaning or has a slight lean the sawyer should use a level or a plumb line to figure out how much lean and what instructions it leans. The sawyer ought to plan the felling operation in the direction of the tree’s existing lean. Trees with structural problems are potentially unsafe candidates for felling. Trees with spiraling of the bark suggest spiraling of the interior wood grains, which might make it difficult to manage the direction of the fall. Trees with dead branches or pockets of rotten wood are also hard to fell by conventional notch and drop operations. The sawyer should analyze the base of the tree. If the base is hollow or one side of the tree has rotten wood, it may not be an ideal choice for felling operations since the rotten wood will impact the direction that the tree falls.

The next action is for the tree sawyer to figure out if the path of the tree’s designated fall is clear of challenges and targets. No individuals or valued targets must be in the pathway of a tree being dropped for a distance of at least 2.0 times the height of the tree from the subject tree’s base (see Drop Zone picture).
The tree sawyer need to make sure there are no obstacles like structures, trees or other physical barriers that will block his/her to escape if the tree begins to stop working without alerting during the cutting operation. The tree sawyer ought to constantly presume that the tree will fall in EVERY possible direction and take measure to guarantee nothing can be hurt regardless of which method the tree falls.
A single error made during a tree felling operation can result in damage to property or major injury or death to the tree feller or spectator. The safe felling of a tree consists of correct tree and website assessment and conformance with appropriate standards for work placing and cutting.
