As the employees pushed and pulled the Hawk Jaw into position, Employee #1 placed his right thumb on the outside of the Hawk Jaw center metal plate enclosing the Hawk Jaw's right control handle. As Employee #1 pulled and the coworker pushed the Hawk Jaw into position, the right metal plate enclosing the Hawk Jaws right center handle came in contact with the rigs drill pipe severing the tip of Employee #1's right thumb off. Upon Employee's #1 injury, the rig crew stopped work and attended to Employee's #1 injury.

At the Long Beach Western Hand Center, minor hand surgery was performed on Employee #1's right hand in which a small portion of Employee #1's right thumb distal phalanx was rongeured and a flab of skin was folded over the thumb.
