Abstract: At 9:00 a.m. on January 2, 2018, Employee #1 and a coworker, employed by a drilling company, were working at a pipeline installation project. Employee #1 was filling fuel cans in a 12-foot by 15-foot metal-framed warming tent. The coworker, who was driving a 1-ton pickup truck, pulled the truck up to the warming tent and then entered the tent. Approximately 10 minutes later, the truck unexpectedly began to roll into the tent. Employee #1 was caught between the truck's front bumper and a 9,900-pound underground boring machine, and his right leg was crushed. Emergency services were called, and Employee #1 was transported and admitted to the hospital. As a result of the crushing injury, Employee #1's right leg required surgical amputation up to the patella (kneecap).
