Which of the following describes two common misuses of pliers?

• A. Using Lineman's pliers as a hammer and using them to strip or cut wires
• B. Using Lineman's pliers to grip and twist bolts
• C. Using Lineman's pliers as a wrench
• D. Using Lineman's pliers to measure torque

Answer: (A)

Pliers are designed for gripping, twisting, and cutting metal, not for hammering or stripping insulation. Using Lineman's pliers as a hammer subjects the tool to impact it isn’t built to absorb, which can deform the jaws, bend the tips, or loosen the pivot and increase the risk of slipping and injury. Stripping insulation with them is also unsafe and imprecise: even if the tool has a cutting edge, dedicated wire strippers or the proper stripping notch provide a cleaner, safer removal of insulation without risking nicking or damaging the conductor. While the pliers can cut wires within their capacity, using them to strip insulation or as a hammer goes beyond their intended purpose and can compromise tool life and safety. Keep pliers for gripping, twisting, and cutting, and use the correct tool for hammering or stripping tasks.
