>Having your employees stay home doesn't help at all. Many of them will be living in the same danger zone, and in fact many will be living in buildings that are less capable of withstanding a tornado.

Single floor factory building built on a concrete slab vs house with a basement.

You really think the factory will win in terms of human safety?

Oh, but of course, thats the whole point of weaseling around the term 'withstanding a tornado'.

I'm sure the factory building will withstand it better, in terms of how much of it will be remaining in the after math, but I'm also sure that the house with a basement is gonna be safer for the humans.
