Abstract: At 12:07 p.m. on October 15, 2020, an employee was pushing sewer lining onto a powered roller located at the rear of a refrigeration trailer. While performing the task, the employee's left hand became caught between the roller and the sewer lining. The employee's left forearm was pulled over the roller until his hard hat made contact with it. Due to the roller's insufficient torque, the employee's body was not pulled over entirely, but his head bounced off the roller several times, causing his hard hat to dislodge. Another employee noticed the situation and turned off the roller. The employee sustained contusions and abrasions and was treated without hospitalization. The powered roller was involved in the incident.
