Abstract: At 8:38 p.m. on Sunday, January 24, 2021, four employees were working for a firm that manufactured tires. Employee #1 was a production supervisor. Employee #2 was a maintenance technician and electrician. She primarily spoke Spanish. Employee #3 was also a production supervisor. Employee #4 operated a lift truck. Tire curing press number 705 was malfunctioning. Employee #1, one of the production supervisors, called for Employee #2, the maintenance technician and electrician, to troubleshoot and repair the curing press. Employer #3, also a supervisor, and Employee #1 watched as Employee #2 worked on the equipment. Employee #4, the lift truck operator, was delivering racks to and removing racks from the curing press. The tire curing press had a bladder that was pressurized by steam. Steam pressure inside the bladder was approximately 13 to 15 psi (90 kPa to 103 kPa). The tire curing press bladder failed, and there was an unexpected release of steam. Apparently all four employees suffered burns. Employees #1, #2, and #3 were hospitalized. Employee #4, the lift truck operator, was treated without hospitalization.
