Okay folks . . . ! I've been waiting for a guy in my neighborhood (who's a respected member of this board), to come over and give me first-hand, on-site advice on this! But . . . he's been really busy, lately!
Sooooo! I'll do my best to describe my situation, here - and, hopefully, you guys can offer some suggestions! Okay?
Alrighty then . . . where to begin . . ?
My house is built into a hill. Downstairs (in what used to be our storage room - approx 18' X 10'), I've created a "safe room," of sorts. Being the part that's built into the hill, this section of the house is the most protected. In it, I have my safe and all my ammo/equipment, food, access to water, toiletries . . . you name it.
The entire downstairs is concrete block and the room is almost completely covered with 'radiant-barrier' insulation, too. So, for a fallout shelter, it's as good as it's going to get, at my place.
The ONE thing I'm lacking is fresh air.
I have two gennys and around 50 gal's of fuel - although, I'm not yet sure how I could turn-on (and fuel), the gennys remotely. Going out to do it would kinda' defeat the purpose of the safe-room! But, that's a conversation for another day . . .
WHAT I'VE BEEN THINKING ABOUT, THOUGH, IS: . . . if I use the genny(s) DAILY (say; for cooking, cooling the fridge/freezer and drawing fresh water, etc), I shoul also be able to use it to bring in fresh, filtered air.
My question is - how?
I DON'T have a furnace or any kind of ductwork in the house. (don't ask!) Since the walls are block, it'd be pretty hard to go through a wall - to the outside, too. I was thinking, though, about cutting a hole in the ONE wall that's NOT block - and that simply goes into another, small room of the house. If I were to mount a fan in that wall, could I build a "box" around it and fill the box with some sort of filtering material?
If so, what kind of filter material? And, what kind of fan will be strong enough to pull the air through such a filter - and NOT burn itself up? (nor be so loud that we couldn't stand it!)
Also . . . if the house is (pretty much), sealed . . . will there be enough air (already IN the house), to support 4 people for . . . say: a week? (Or, until radiation levels would have dropped enough to emerge from the shelter?) The area of the house is about 30' X 60' X 2 floors. Inside the small room (from which the filtered air would be drawn - approx 6' X 10'), is a small, shuttered "window" that opens to the rest of the house.
I figure I could put a FIRST layer of filter material across that "window" for some added protection from particles in the air. Then, the air would hit the "filter box" - BEFORE being blown into the safe room.
Am I on the right track, you think?
Further . . . if I get this figured out . . . would I need an "exhaust port?" Or, somewhere for the "old" air to go? If so, how would you reccommend constructing that? It'd have to be sealed - when not in use. Right? Yet, open when positive pressure was exerted against it. Am I correct?
I know it'd be smart to have a couple CO2 sensors, too . . .
Boy! Any help will be GREATLY appreciated! I'm not all that far from Three Mile Island, after all! Plus, Gettysburg is surrounded by cities that are prime targets. Personally, I think (given the way things are looking), I should've had this done by now! Time may very well be running out!
How's that saying go - about paranoia? "It's only paranoia if . . . ?"
