Abstract: At approximately 3:00 a.m. on September 13, 2021, an employee working as a printing machine operator for a commercial printing company was troubleshooting a paper feeding issue on an SP printing press. The employee reported reaching around the machine to check for air leaks when he lost balance. In an attempt to prevent a fall, the employee grabbed an area of the machine located above the guard that protects the motor belt assembly. During this action, the employee's left-hand fingers became caught in the belt assembly, resulting in an injury. The employee was hospitalized and three fingertips below the fingernails were surgically amputated.
