What is a primary concern when using power saws without a blade guard?

Using power saws without a blade guard significantly increases the potential for injury, which is a primary concern. Blade guards are designed to protect users from the exposed blade when the saw is not in use and help prevent accidental contact during operation. The absence of a blade guard leaves the blade vulnerable, increasing the risk of cuts, lacerations, or even more severe injuries if a user accidentally brushes against it or if a kickback occurs. Safety features like guards are crucial in ensuring that users can operate power saws without exposing themselves to unnecessary risks, making injury prevention the foremost concern in this scenario. While accuracy of cuts, noise levels, and speed of operation are important considerations when using power saws, they do not compare to the critical safety issues posed by the lack of proper guarding.
