Q&A for How to Build a Safe Room

Possibly. If it is just a sheet, no. But if it is backed by wood or concrete, your chances rise significantly.

Go to your local hardware store or look online for options.

Use commercial building machinery. Classes are available at a variety of places to learn the operation of these tools, and they can often be rented from construction companies. Alternatively, you can hire a construction company to break in land for you, and possibly even build the main body of the safe room. If you aren't dead set on a particular place, another option would be to utilize natural land formations to build your safe room. A shallow cave or rocky outcropping can provide a good natural blueprint for a room, and with some concrete, rebar, and sanding work, can be shaped into secure rooms by cutting into the rock.

You can use an electric fan if you have a power outlet. If not, then you can use plant potted plants in the underground shelter, since trees produce oxygen, which humans can breathe as air. But if you are doing this, make sure you have a 15 gallon water supply, since watering a plant 1/4 cups of water each 2 days, the water supply will last about 120 days and that will probably be enough.

A safe room can be used not only for burglary protection but also for natural disasters or to keep valuables safe from a fire.

You can use smaller air filters and install a 90-degree bend in the air supply to help keep out bullets and intruders.
