Abstract
A system and method is provided for locking a lug-type rotary closure assembly in a closed position. The locking arrangement includes a pressure warning device, which may also release internal pressure. The system cannot be unlocked and hence the closure cannot be opened, until the pressure warning device has been moved to a position where it will warn of internal pressure and/or release internal pressure.
