How we size it
The numbers
behind it.
Two ways out
The residential code requires an emergency escape opening for basement sleeping rooms, and every bunker we build has a second exit.
Pressure ratings
NBC hatches and vault doors are rated in pounds per square inch of overpressure, with double gas seals. We match them to the air system's blast valves.
Bullet resistance
UL 752 rates doors by level. Higher levels stop more powerful rounds and cost much more.
Radiation detection
A dosimeter tells you the dose rate outside and when it is safe to leave. Fallout decays quickly: the 7:10 rule says every sevenfold increase in time cuts the dose rate about tenfold.
Questions
About
protection.
Is a blast door necessary?
For fallout and storms, a sealed, gas-tight door and filtered air matter most. Blast ratings matter closer to likely targets. We help you choose for your location.
What is an escape tunnel?
A second, separate route out of the bunker, used if the main entry is blocked by debris, fire or collapse.
Why include radiation detectors?
Because the only way to know whether the air outside is safe is to measure it.
