What safety features are required for power tools used in the workplace?

The correct response emphasizes the necessity of properly fitting guards and safety switches as essential safety features for power tools used in the workplace. These elements are crucial for protecting workers from accidental injuries. Guards are physical barriers that prevent access to moving parts of the tool, reducing the risk of cuts or entanglements during operation. Safety switches, which can be designed to require two-handed operation or to cut power when the tool is released, help ensure that the tool does not operate unexpectedly.

While other options outline features that may enhance the usability or convenience of power tools, they do not directly contribute to the safety of the tools in a work environment. For instance, a lightweight body can make tools easier to handle, but it does not inherently protect users. Battery-operated capabilities and Bluetooth technology may provide advantages in terms of mobility or control, yet these aspects do not address the fundamental safety needs when operating power tools. Thus, the emphasis on safety features like guards and safety switches is paramount for maintaining a safe working environment.
