Felling of trees is among the most typical jobs performed throughout logging and arboricultural operations. It is a possibly unsafe and difficult operation that needs the sawyer (chainsaw operator) to know trees, be healthy, and be trained in tree felling operations.
The most common technique tree fellers use is a multi-step process that initially includes the development of an open-faced notch in the trunk. Inappropriately carried out cuts, the creation of the notch positions the fixed load of the tree such that the lawyer, through using the back cut and the staying hinge, can dependably control the direction the tree will fall. However, mistakes made during felling can result in residential or commercial property damage or severe injury/death to the feller or onlookers.
Safe felling operations begin with proper assessment of the tree and of the conditions in an area 2.0 times the height of the tree to ensure it is totally free of individuals & residential or commercial property. Sawyers must make informed decisions regarding the style of notch, as well as the depth of each cut to safely and reliably fell trees.

- the Sloping Cut
- the Back Cut
These cuts must be done by a sawyer who has actually been trained and uses the appropriate individual protective equipment like gloves, eye security, hearing defense, head defense with face guard, chainsaw chaps, and steel-toed boots. The chainsaw chosen for felling trees should be the suitable size (bar length) for cutting the subject tree and must be sharp and in good repair work. Having the suitable devices like tree felling wedges, taglines, and other tree felling equipment may assist in the effective and safe felling of trees.
The initial step in felling a tree is for the sawyer to look for a straight tree and has an equivalent size diameter that is devoid of bulges or irregular architecture. If the tree is leaning or has a minor lean the sawyer needs to utilize a level or a plumb line to identify just how much lean and what direction it leans. The sawyer needs to prepare the felling operation in the instructions of the tree’s existing lean. Trees with structural defects are potentially unsafe candidates for felling. Trees with spiraling of the bark suggest spiraling of the interior wood grains, which may make it difficult to manage the instructions of the fall. Trees with dead branches or pockets of rotten wood are likewise hard to fell by standard notch and drop operations. The sawyer should examine 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 option for felling operations because the rotten wood will affect the direction that the tree falls.
The tree sawyer ought to make sure there are no obstacles like structures, trees or other physical barriers that will obstruct his/her to leave if the tree starts to fail without alerting throughout the cutting operation. The tree sawyer must always presume that the tree will fall in EVERY possible instructions and take step to ensure absolutely nothing can be damaged regardless of which way the tree falls.
Foreseeable and avoidable Injuries, deaths and damages
Tree felling is a tough and hazardous operation that must just be undertaken by individuals who have the correct training and experience. A single mistake made during a tree felling operation can lead to damage to property or severe injury or death to the tree feller or onlooker. The safe felling of a tree consists of appropriate tree and site examination and conformance with suitable standards for work positioning and cutting. The vast majority of injuries and occurrences can be prevented if these requirements and strategies are followed.
If the path of the tree’s desired fall is clear of challenges and targets, the next step is for the tree sawyer to determine. No individuals or valued targets ought to remain in the pathway of a tree being dropped for a distance of a minimum of 2.0 times the height of the tree from the subject tree’s base (see Drop Zone image).
