Pulowski Preservation shelter

Pulowski Preservation shelters are coin-operated, one-person fallout shelters found on street corners throughout the more urban areas of the Capital Wasteland, provided by Pulowski Preservation Services. Advertised as a "sensible" and "affordable" alternative to the Vaults, people would ostensibly use them as a last-minute resort in the event of a nuclear attack. The shelter itself is firmly secured to the ground, and ventilation piping is attached to the rear of the booth. A luminous sign on the front of the shelter indicates whether it is occupied or not.

Pre-War use
Though the shelters can shield against explosive force, they do not seem to shield against radiation. It could be speculated that the installation of so many booths may be seen as a profiteering scheme in the climate of fear before the Great War began, or they may be simply in disrepair when found by the player. The shelters only had an air supply, no food or water, so the occupant's survival was dependent on what they were carrying at the time. Whether any occupant survived through the use of these shelters is unknown, though many are filled with skeletons, suggesting the majority of occupants died trapped inside. The last-minute nature of the booth meant that ill-prepared occupants were likely resigned to die from starvation if they survived the high radiation levels. Considering the blood splatters within several booths containing handguns, it seems that some occupants committed suicide after losing all hope of survival. The only advice offered after entering the booth is: "Wait for radiation to clear. Enjoy your stay." Although somewhat illogical, it seems these shelters were intended to be reusable; considering the tone of advertising the shelters were given, the risk and cost of nuclear devastation pre-War was likely greatly underestimated by the general public.

Post-War use
Though apparently coin operated, the player character can enter simply by pressing on the coin-slot (note no money will be taken when pressing the coin slot). Two centuries later, Pulowski shelters have found new use in protecting citizens of the Wasteland from its dangers; at least one non-player character (Bryan Wilks in "Those!") hides in a Pulowski shelter. Conversely, in Paradise Falls the shelters are used as punishment cells; a Pulowski shelter at the far end of the settlement is used to detain unruly slaves, and is named "The Box" (An object known as "The Box" was also mentioned in Fallout Tactics, by General Simon Barnaky). This shelter is unique in that it has also been modified to be lockable, imprisoning the slave (in this case, Rory Maclaren). The key to this shelter is in possession of Forty, typically nearby sitting on a bench or patrolling around the destroyed car wall.

There is also a Preservation shelter located in Point Lookout, in the Boardwalk area. It is not meant to be encountered during normal play and can only be reached with console or through strategic jumping. Additionally, it cannot be opened. It is placed there for technical reasons, as it houses the non-player character The Brain which serves as the dialog source for Professor Calvert when discouraging you from deploying the cogwave jammer.
