ABSTRACT:
A closure safety interlock system is provided for a pressure vessel having a closure assembly with a primary locking system. The closure safety interlock defines a secondary locking system for assuring that the primary locking system may be opened only by following a proper sequence, thereby minimizing misuse of the primary locking system. The closure safety interlock includes a blocking member movable between an engaged position and a disengaged position for blocking movement of a primary lock when in the engaged position and until a release mechanism in the primary lock has been activated. A mechanism is provided for moving the blocking member from the engaged position to the disengaged position once the release mechanism has been activated.
