In Canada, chainsaws are primarily used by utility arborists in the utility line clearing sector for the removal of brush, diseased trees, and branches that have the potential to interfere with electrical lines. Aerial devices with chainsaws may be required to perform operations above certain heights, including tree canopies. One of the most significant concerns during these operations is the risk of injury and harm to chainsaw operators and those in the surrounding area. Currently there is no safety locking mechanism on the marketplace for a chainsaw scabbard. As a result, during repositioning of the aerial device the chainsaw can be released from the scabbard with the potential to cause serious injury and harm. The primary objective of this research is to design and produce a mechanical locking safety mechanism for a chainsaw scabbard. The safety mechanism will keep the chainsaw from dislodging from the scabbard during repositioning of the aerial device. To achieve this goal background research will first be conducted to determine current technologies on the market, issues and concerns with these products and optimal materials to be used in the development of a prototype. Following this, a prototype will be designed and constructed. Electrical testing and ergonomic evaluation of the prototype will be performed and summarized in a final report. The results from this applied research will allow Hydro One to develop a product addressing a much needed safety concern, and ensure a safe working environment for their employees.

在加拿大，链锯主要由公用事业树木师在公用事业线路清理部门使用，用于清除可能干扰电线的灌木、患病树木和树枝。 可能需要带链锯的空中设备在一定高度以上执行操作，包括树冠。 在这些作业中，最令人关切的问题之一是链锯操作员和周围地区的人有受伤和受到伤害的风险。 目前，市场上没有用于链锯鞘的安全锁定机构。 因此，在重新定位航空装置期间，链锯可能从鞘中释放，从而可能造成严重的伤害和损害。 本研究的主要目的是设计并制造一种链锯刀鞘的机械锁紧安全机构。安全机构将防止电锯在空中装置的重新定位期间从鞘中移出。为了实现这一目标，将首先进行背景研究，以确定市场上的当前技术，这些产品的问题和关注点以及原型开发中使用的最佳材料。 在此之后，将设计和建造原型。 将对原型进行电气测试和人体工程学评价，并在最终报告中进行总结。 这项应用研究的结果将使Hydro One能够开发出一种解决急需的安全问题的产品，并确保为员工提供安全的工作环境。
