The plastic & duct tape are for sealing a room against toxins & radioactive debris, right?

Okay, I've got 1872 cubic feet of air in here... How long will that last? If one Evacu-8 hood lasts for 20 minutes, I would need.... (poking claculator)... 216 hoods & cannisters to survive for 3 days.

Oh-oh, what about the dog and three cats? If I stick the dog's tennis ball in her mouth before I put her hood on, will it slow down her breathing? Can I stick an entire cat inside a hood? I wonder if anyone has tested how long the air lasts per cat? Does size matter?

Maybe SCBA tanks would be more cost effective.

WAIT! Plants absorb carbon dioxide & produce oxygen, right? How many plants would I need to support the five of us? Do they only produce oxygen when exposed to light? If so, just how many flashlights will I need? How many extra batteries? If the cats use that rubber plant for a scatching post, does that make it produce less oxygen?

Is it better to die from suffocation or something else? Does a kings-X work if it was a false alarm?

This all seems rather complicated to me. I think I need to work out a few more details.... <img src="/images/graemlins/cool.gif" alt="" />
