In terms of safety, what is a crucial step before using any electric tool?

Inspecting electric tools before each use is essential for safety because it helps identify any potential hazards that could lead to electrical shock, tool malfunction, or accidents during operation. This practice involves checking for signs of wear and damage, such as frayed cords, loose parts, or malfunctioning switches. By ensuring the tool is in optimal working condition, users can significantly reduce the risk of injury and ensure effective performance.

Other options are less directly related to immediate safety concerns. For example, while determining if the tool is appropriate for the job is important for effectiveness and efficiency, it does not address the condition of the tool itself. Keeping track of model numbers or checking the manufacturer's website may provide useful information, but these actions do not contribute directly toward ensuring the safety of the equipment for immediate use. Thus, regular inspections remain the most crucial and proactive step in maintaining safety when working with electric tools.
