## Narrative

While lifting a jaw crusher toggle block, an electric hoist chain swung and mashed a maintenance mechanic's left thumb against a nearby beam of the crusher frame.  The mechanic was guiding the block through the frame when the block cleared the jaw and swung free.  The incident resulted in a laceration requiring 9 stitches, loss of thumbnail and broken tip of the bone.
