Abstract: At 12:35 p.m. on March 4, 2020, an employee, a machine operator, was on the vacuum forming department, operating vacuum forming machine #2, a thermo-setting plastic molding press. When he noticed a wrinkle that had formed in the plastic material within the machine, he entered the space between the upper and lower platens to smooth out the wrinkle with his hands. As he was attempting to smooth the wrinkle, the lower platen activated. He was crushed between the upper and lower platen of the press. The employee was taken to Pomona Valley Hospital Medical Center. He sustained burns and fractures to his ribs, requiring hospitalization greater than 24 hours.
