What safety features are required on workplace power tools?

The choice that includes properly fitting guards and appropriate safety switches is the correct answer because these features are essential for protecting workers from potential hazards when using power tools. Guards are designed to prevent accidental contact with moving parts, reducing the risk of cuts, abrasions, or more severe injuries. Appropriate safety switches, such as power switches that require a two-handed operation or are designed to prevent accidental activation, enhance user safety further.

In contrast, emergency shut-off switches alone do not provide comprehensive protection since they are reactive rather than preventative measures. While lightweight materials may assist with user handling, they do not address safety requirements directly. Color-coded cables might enhance visibility or organization, but they do not constitute a safety feature specific to the operational mechanics of power tools. Overall, the focus on proper guards and safety switches aligns with workplace safety regulations and best practices.
