What type of hammer should never be used for electrical work?

A hammer with a damaged or loose head should never be used for electrical work because it poses significant safety risks. When performing electrical tasks, it is crucial to maintain a strict standard of tool integrity. A hammer with a compromised head can break apart during use, potentially causing injury to the user or others nearby. If a hammer's head comes loose, it can detach completely, leading to accidents involving falling objects that can strike or injure someone, especially in a context where electrical components are involved.

Moreover, ensuring that tools are in good condition is vital in preventing unintended contact with live wires or electrical components. A secure and well-maintained hammer is essential to avoid any situations that may unintentionally escalate to electrical hazards, especially if the hammer strikes an object that could lead to an electrical short circuit or arc. Hence, safety depends on using tools that are intact and reliable during electrical work.
