What describes a dangerous condition that can happen to an impact tool?

Mushrooming occurs when the striking end of an impact tool, such as a hammer or chisel, becomes deformed, resembling a mushroom cap. This can happen due to repeated impact against hard surfaces, causing metal to bulge outwards. The deformation of the tool not only alters its functionality but also creates a safety hazard. A mushroomed tool can easily chip or break upon further use, potentially causing metal fragments to fly off and leading to injury for the user or bystanders. Proper maintenance and regular inspections of impact tools are essential to prevent this dangerous condition, allowing for safe and effective use.
