A '''blast door''' is a type of heavy [[door]] designed to withstand large amounts of damage, especially by explosives, or to seal pressurized compartments on a starship in case of a [[hull breach]]. | |||
==Background== | |||
Blast doors are an important safety measure for many starships or space stations. Blast doors are similar to [[airlock]]s in that they are used to seal off areas suffocating, or have a strong possibility of suffocating a breach and loss of atmosphere. They are distinguished by their interlocking sections that rise from the floor, and drop from the ceiling. The {{UNSCShip|Pillar of Autumn}}s blast doors had large panels of what seem to be high-strength plexi-glass, since it can resist blasts of plasma from the handheld [[Plasma Rifle]]. | |||

On the ''Pillar of Autumn'', the blast doors were also used to trap [[Covenant]] [[Boarding (attack)|boarding parties]]. This is an efficient way of cutting off boarding parties, as the doors are built to be extremely resilient to damage.<ref name="poa"/> | |||
Blast doors are also commonly used in blast shelters, [[military base]]s or other locations where heavy, secure doors are necessary. The city of [[New Mombasa]] had heavy blast doors in its tunnel systems and separating its city compartments, to seal off select areas in case of an emergency.<ref>'''[[Halo 3: ODST]]''', campaign level ''[[Mombasa Streets]]''</ref> | |||
