Abstract: On May 31, 2012, an employee was working as a press operator for a small tooling company. He had worked for the company for 6 years. On the day of the incident, the employee was operating a Bliss OBI 10-ton (89-kilonewton) punch press, making lightweight washers. As the washers were punched out of the material, an air hose blew them off the line into a bucket. The air line was not blowing the parts clear, so the employee stopped the machine and began to adjust the air line. The press inadvertently began a stroke and struck both hands of the employee. The employee lost the tips of the middle finger on his right hand and the ring finger on his left hand.
