On July 21, 2017, an employee was working on a water leak from a clogged piping system. The piping system ran from the boiler to a manhole in the discharge area. The employee went into the manhole and put a plug in the piping system to help find the leak. The blockage was located and corrected. At around 12:30 PM, the employee went back into the manhole to remove the plug. When the employee removed the plug, hot water spewed onto the employee's right leg, buttock, and thigh, causing burns that required hospitalization.
