Landscaping License Practice Test

Which of the following is safest when you are finished with a power tool?

1. Unplug the machine immediately

2. Wait until all motion has stopped before leaving the machine

3. Leave the machine running for ventilation

4. Turn off the power switch and walk away

The correct answer is: Wait until all motion has stopped before leaving the machine

The safest practice when finishing with a power tool is to wait until all motion has stopped before leaving the machine. This is crucial because even if a tool is turned off, certain components may continue to move for a short period. Waiting ensures that all blades or moving parts have come to a complete stop, minimizing the risk of accidental injury to yourself or others in the vicinity. This precaution is a key safety measure in operating power tools and aligns with best practices for ensuring a safe working environment. Unplugging the machine immediately, while generally safe, can be impractical as it does not address the potential for residual movement during the power-down phase. Leaving the machine running for ventilation poses clear safety risks, as it increases the likelihood of accidents while the tool is unattended. Turning off the power switch without ensuring that all parts have stopped could also lead to accidents, as there might still be momentum. Therefore, the practice of ensuring everything has completely stopped fosters a safer and more responsible approach to power tool usage.
