Clearing any system with instrument air as a pressure source is a bad idea. Other pneumatic sources, such as utility air, plant air, or nitrogen, should be used instead. However, the Three Mile Island instrument air was at a lower pressure than the water stream on the resin polisher system. Despite the presence of check valves, there was a reverse flow water entered the instrument air system causing several instruments to fail, and the turbine tripped. Through a series of other errors, the water covering of the radioactive core was uncovered, allowing an escape of a small amount of radioactivity. Due to the widespread negative public reaction, the U.S. nuclear industry received a setback. If it were not for that improper hose connection or the erroneous one-minute modification,... 

The reactors were equipped with interlocks to prevent opening the reactor drain valve if the reactor was pressurized. The CSB theorized that the blaster operator believed he was at the correct reactor and the bottom valve on Reactor D310 was not properly functioning. The CSB established that bottom valve actuator air hoses were found disconnected. Furthermore the emergency air hose to bypass the interlock was comiected [8]. This is obvious part of a Human Error type incident.
