I had a supervisor once who was angry with me for not removing the proportional flow water control linkage valve to a 5,000hp boiler in our factory. The boiler went into shutdown due to a low water condition. I explained that "it would be six to ten hours before I could introduce makeup water to take it out of a low water shutdown condition". He was furious over lost production and insisted on uncoupling the linkage and bypassing the safety control, letting line pressure water in to fill the low water / super high temperature boiler vessel.
Note I said I "had a supervisor". It blew the 3/8" plate boiler steel wide open. The pop-off relief valves could not vent that many cubic feet of steam expansion in such an explosive state. He was very fortunate he wasn't killed.
He was terminated after it was certain he was ok and drug tested.
