Abstract: At approximately 2:00 p.m. on July 18, 2019, an employee was cleaning/adjusting small nozzles on a filter press. The employee opened the cabinet housing the water spray nozzle (a horizontal pipe with many small nozzles that sprays water onto the filter media, which is a continuous belt with porous canvas-like material). As the employee was adjusting the spray nozzle, his hand was caught by the material and pulled into a horizontal roller where the fabric changed direction as it moved toward the Sulphur that it was filtering the water out of to create a Sulphur cake. The employee's left fingers, hand, and arm were caught by the fabric and pulled into the horizontal steel roller up to the elbow causing a crushing injury. The filter fabric operated in a continuous loop, and the horizontal steel roller. The employee was hospitalized for three days to treat these injuries.
