Which of the following is true about using hammers?

Worn hammers should indeed be replaced because their effectiveness is compromised over time. A hammer with a worn or damaged head can lead to decreased performance, which may result in improper striking and potential safety hazards. For instance, a worn hammer may not deliver sufficient force, or worse, it could break during use, sending fragments flying and risking injury to the user or those nearby. Ensuring that tools are in good condition is a critical aspect of maintaining a safe work environment, particularly in trades such as pipefitting, where precision and safety are paramount. Regular inspections and timely replacements are essential practices for effective tool management and occupational safety.
