What should be ensured when using portable power tools?

When using portable power tools, proper grounding and safety when working at height are essential for preventing electrical hazards and ensuring worker safety. Grounding helps to direct any accidental electrical currents away from the user, thereby reducing the risk of electric shock. This is particularly important in environments where there might be moisture or other conductive materials present.

Additionally, when operating tools at height, it is crucial to implement safety measures such as using harnesses or guardrails to prevent falls, which can result in serious injuries. Therefore, ensuring that tools are properly grounded and that safety protocols are followed when working at elevations contributes significantly to a safer work environment.

The other options do not foster safe practices when using portable power tools. Using tools in wet conditions increases the risk of electrical shock, working without safety goggles exposes the user to eye injuries from debris or sparks, and running tools without inspection can lead to malfunction or accidents. Each of these actions disregards crucial safety protocols, further underscoring the importance of proper grounding and adhering to safety measures while using power tools.
