Which is a critical safety measure for preventing accidents with power tools in the workplace?

Using a tool for its intended purpose is a fundamental safety measure that significantly reduces the risk of accidents in the workplace. When tools are used as designed, they operate within their engineered specifications, which minimizes the chances of malfunctions or unexpected behavior. For example, using a drill for drilling and not for prying or hammering reduces the risk of injury from tool failure.

Additionally, using tools for their intended purposes ensures that the operators are familiar with the expected operations and risks, allowing them to maintain better control and awareness of their environment. This understanding is critical in preventing misuse that can lead to accidents.

While the other options present important safety considerations, they do not directly address the fundamental principle of proper tool use, which is essential to preventing accidents associated with power tools.
