Abstract: At 6:00 p.m. on July 15, 2020, Employee #1 and coworkers, employed by a civil engineering construction company, were engaged in a week-long assignment to clear a creek bed of vegetation so a concrete flood control channel could be installed. They worked for 8 to 10 hours per day using STHL FS 111 R gasoline-powered trimmers that weighed approximately 12 pounds, brush cutters, and machetes to cut and hack at branches, trees, and vegetation. Employee #1 was found unconscious by a coworker. The supervisor performed CPR while waiting for emergency services to arrive. Employee #1 was transported to the hospital, where he was pronounced dead. Cause of death was heat-related illness.
