Nuclear / Biological / Chemical Fallout Shelters

Safecastle prefabricated fallout shelters are made of steel up to 7/16" thick. The primary differences between our storm shelters and our fallout shelters are found in modifications to the door, steps, and air vents to make them virtually impervious to radiological, biological, or chemical contamination.

NOTE: Our fallout shelters come standard with a 12-person Swiss-made chemical and biological air filtration system with both electrical and hand-powered capability. We also offer larger systems at additional cost.

To some extent, our shelters also provide blast protection, depending upon proximity to and power of a blast. As with all our shelters, your NBC / fallout shelter is made to your size specifications.

Fallout Shelter with Hatch Door or Entry Door
The most inexpensive approach to installing a Safecastle fallout shelter is to opt for a shelter with a 32"-square blast-door hatch. The door base is built in a way so that you can put two layers of boards and two layers of sand bags to prevent radiation from penetrating that hatch entrance "weak point." The rest of the shelter is already adequately protected from fallout radiation by the dirt/fill shielding on top of the shelter.

A popular alternative is to install a 30" x 72" door which extends 30" above the top of the shelter.

Reference to our Door Bases
Our fallout shelters come with a standard door base 30" tall. This will put the door entrance just above the ground level. The top of the shelter will be approximately 30" below ground. Any door base that extends above the top of the shelter more than the standard 30" base, has to be hauled separately from the shelter. This door base over 30" tall will have a door 32" wide and 32" long with ladder type steps going down into the shelter.
