Hmm, my plan was (is?):

1. train spills!
2. put on a full-face respirator
3. get in the car
4. run away!!!

The respirator is meant for temporary use. But then I realized that I may not be able to get away. Or the get away may be too slow to be safe. Everyone will be trying to do the same thing, after all. We will have evacuation traffic.

So that makes sealing a room important. It seems like that means I have to have a room always sealed and ready for refuge. I am assuming that after a spill happens, I won't have time to leisurely find the plastic rolls, get the ladder, tape up the windows, etc... Further, I suspect that my house is poorly insulated, with tiny, invisible gaps in the floor and ceiling that some form of gas can get through. But let's set that problem aside. Just having a room where the major portals like windows and doors are sealed most of the time seems kind of impractical.

What do you guys think?
