Containment shields were installed in the Bright Hope and were activated during their retreat from the Battle of Hoth. Unfortunately, the containment shields could not contain the explosive depressurization that occurred on many decks, including passenger level 1, and several lives were lost."@en . "The Containment Shield was an energy shield wall within the Sentinel Wall around Installation 05's Library, built by the Forerunners. It helped contain and enclose the Flood inside the Quarantine Zone, and keep out anything that could sustain the Flood. It also appears to be a sort of energy field that doesn't allow anything through either way. It had to be lowered and deactivated in order for Covenant forces to enter the Library and recover the Activation Index."@en . "Containment Shield"@en .
