Securis

Securis is one of the brands of bulkhead used throughout Rapture. Their primary purpose is to limit any flooding that could occur to smaller areas by forming a water-tight seal for easier management and repair. Although this function is accomplished, they are known to be unable to handle the pressure of the water at the city's depth. During cases of severe leaks, the doors will sometimes buckle and leak past their bounds, eventually resulting in failure of the bulkhead and flooding of the next immediate area. Most of the Securis bulkheads are programmed to seal automatically in the case of severe flooding or other type of damage.
