Which of the following is an essential component of power tool safety?

Inspecting tools for damage before use is crucial for power tool safety. This practice helps identify any defects or hazards that could lead to accidents or malfunctions while operating the equipment. Checking for frayed cords, loose parts, or worn components ensures that the tool is in safe working condition before it is used, significantly reducing the risk of injury. Regular inspections can prevent unexpected failures, promote longevity of the tool, and ensure that safety features are functioning properly.

The other options do not enhance safety. Wearing sandals does not provide adequate foot protection, which is necessary when working with potentially hazardous equipment. Using a tool with both hands is advisable for maintaining control, but it is not universally practical for all tools and tasks. Ignoring tool reviews directly contradicts safe practices, as reviews often provide important information about performance and possible safety issues.
