## Narrative

An employee was removing clevises from under a blowout preventer (BOP). The employee retrieved the first clevis, but the second clevis was trapped underneath one of the BOPs. He lifted the BOP up and stuck the first clevis underneath to support the BOP's weight (this allowed him to retrieve the second clevis). When he attempted to lift the BOP back up to remove the first clevis, the BOP slipped and fell. His right index fingertip was caught/pinched between the two BOPs, resulting in a finger amputation.
