What is the safety concern with making a deep felling notch?

In the context of tree felling, a deep felling notch is a critical aspect of ensuring safety and control during the cutting process. Making a deep notch can significantly increase the risk of barber chair failure. Barber chairing occurs when a tree might split vertically as it begins to fall, with one side of the tree potentially rolling back toward the cutter. This behavior is often exacerbated by the presence of a deep notch, which can compromise the structural integrity of the tree and create an uncontrolled fall.

The correct choice highlights a significant safety concern in arboriculture and logging, emphasizing the importance of maintaining proper cutting techniques to prevent serious accidents. Properly-designed notches that are not excessively deep help to maintain the integrity of the tree during the felling process. Ultimately, understanding the implications of notching techniques is crucial for safe and effective tree felling operations.
