Abstract: At 9:15 a.m. on January 25, 2019, an employee, a service technician, was cleaning an industrial chiller at the employer's facility. The employee was unaware of a lockout/tagout procedure for the chiller and had not been trained in any lockout/tagout procedures. The employee attempted to clean the chiller but did not disconnect the power on the machine. The employee inadvertently stuck his left pinky finger in a moving fan blade of the chiller and his finger was amputated. The employee was hospitalized from his injury. The employee's supervisor was not present and did not witness the accident.
