Abstract: At 10:00 p.m. on January 28, 2021, an employee was receiving disks from the furnace line using tongs and moving them to a Grimco press which had three rams. The right-side ram had two outer hydraulic cylinders used to assist raising the ram back up and a central press for downward tonnage. Four bolts held each cylinder underneath the press and were screwed into place using a lock washer. The four bolts became disconnected, causing the cylinder to fail and the Megaflow AW hydraulic oil was ignited from the heat of parts coming out of the furnace. This event created a large fireball and pressure wave, and the employee sustained burns on multiple parts of the body. The employee was hospitalized.
