Abstract: At 12:00 p.m. on January 4, 2021, Employee #1 and coworkers, employed by a mobile water pump drilling and maintenance company, were loading a water pump that weighed approximately 1,000 pounds onto a pickup truck. They were using the derrick mounted on the main rig, cables and pulleys. During this process, which involved guiding the water pump by hand, Employee #1 put his gloved hand in front of a pulley. As the pulley was operating, his gloved right ring finger was pulled into the pulley, resulting in a laceration and partial amputation. The employee received medical treatment for the partial amputation but was not hospitalized.
