During inspection of an impact tool, which indication suggests danger?

• A. A cracked grip
• B. A mushroomed head
• C. A loose handle
• D. A warped head

Answer: (B)

A mushroomed head shows the tool head has deformed from repeated impact, bulging outward at the face. This deformation weakens the connection to the handle and creates sharp edges, increasing the risk that the head can crack, detach, or shatter during use. Those failures can send fragments flying or cause the tool to slip, posing a serious injury hazard. While other issues like a cracked grip, a loose handle, or a warped head are also unsafe, mushrooming directly signals metal fatigue and an imminent failure mode, making it the clearest danger indicator. Retire the tool from service and replace or repair it before further use.
