Abstract: At 2:15 p.m. on July 26, 2019, an employee was using a Burr King Model 760 Three Wheel Grinder mounted on a tabletop to grind a 4-inch by 6-inch metal plate. The procedure requires that the employee grind from side to side but the employee was grinding top to bottom instead. Due to the improper mounting of the grinder, the plate the employee was grinding slipped. The employee tried to grab the plate and caught his thumb between the plate and the table. The employee fractured his left hand middle finger, ring finger, and pinky. There were no witnesses to the incident. Coworker #1 alerted Coworker #2 (Supervisor) and Coworker #2 responded immediately. Coworker #2 called Coworker #3 (Manager) who in turn called 911. Emergency Medical Technicians arrived almost immediately, assessed the employee and transported him to the hospital, where he received medical treatment without hospitalization.
