At 10:15 a.m. on June 14, 2019, Employee #1 and coworkers, employed by a construction company, were working at a commercial site. A drive casing was being suspended by a sling and moved to its place in a table opening. Employee #1's right hand was directly below the suspended casing when the casing slipped from the sling, fell, and struck the employee's hand. The employee was transported to the hospital and admitted for treatment of the hand injuries, including a fractured right pinky finger and a deep laceration to the lateral aspect of the right hand that led to amputation of the pinky finger.

Incident on Feb 26, 2014: Employee severely injures hand on oil rig
At approximately 9:40 a.m. on February 26, 2014, Employee #1, a mechanic, was wo rking for a drilling company. The company specialized in environmental drilling to determine the presence and absence of subsurface contamination. Employee #1 a nd two coworkers, were assigned to a three-man crew and tasked with re-spooling 0.625 in. wire rope back onto the drum on Rig Number S1095 (Air Rotary Rig TH50) . While re-spooling the wire rope, Employee #1 maintained tension on the wire ro pe, as one coworker operated the controls to the winch line lever and the other coworker, the lead mechanic, ensured the wire rope was spooled correctly onto th e drum. As the wire rope continued to spool, Employee #1 released tension on the wire because the block itself provided tension while the wire traveled vertical ly. The bolts on the outer face of the block caught the lip of the lower drill t able. Employee #1 grabbed the block (Single-sheave Block Number 280) with his ha nds in order to pull it free. Employee #1's right hand was caught in the pinch p oint created by the sheave and the wire rope. Once freed, the block continued to travel vertically resulting in a serious injury to his right hand. Employee #1 was transported to a medical center, where he was treated and hospitalized for t he serious hand injury, which possibly involved a hand amputation.
