What is a common precaution to take when using power tools?

When using power tools, a fundamental safety measure is to disconnect tools during maintenance. This precaution is critical because it helps prevent accidental startup, which could lead to serious injuries or accidents while you are working on or near the tool. Ensuring that a power tool is unplugged or that the battery is removed during maintenance eliminates the risk of unintended activation.

Maintaining a safe work environment, including ensuring proper ventilation, and wearing appropriate clothing are indeed important practices when using power tools, but they are secondary to directly avoiding the risks associated with the tools themselves. Disconnecting tools during maintenance is a direct safety measure that directly addresses the potential hazards presented by the power tools in use.
