Explanation:

When working unsafely with machines, the force and power of the machinery can lead to severe injuries. Amputation occurs when a body part (like a finger, hand, or limb) is completely cut off by the machine's moving parts (such as blades, rollers, or gears). Bruising is a less severe soft - tissue injury, and while broken bones are serious, the nature of machine operations (with their ability to completely sever body parts due to sharp or powerful components) makes amputation a very common and distinct type of injury in such unsafe machine - working scenarios.
