NCCER Power Tools Practice Exam

When a power tool's cable is frayed or damaged, the safest and most responsible action is to immediately stop using the tool and either replace or repair the cable. A frayed or damaged cable poses a significant safety risk, as it can lead to electrical shocks, shorts, or even fires. Continuing to use a tool with compromised wiring significantly increases the likelihood of accidents and injuries.

Proper maintenance and safety practices dictate that any electrical component that shows signs of wear or damage should be addressed promptly. Replacing or repairing the damaged cable ensures that the tool can operate safely and effectively, maintaining electrical integrity without jeopardizing the user’s safety.

Other approaches, such as improvising a temporary fix with tape or delaying action until routine maintenance, do not adequately address the inherent dangers of using a damaged power tool. Such methods may offer a short-term solution but do not eliminate the risk associated with continued use of faulty equipment, rendering them unsafe and unreliable choices.
