Thanks, Jet. Your comments are always informative and worthwhile. This particulat kit is a high-rise BoB for employees. I would not have thought that space blanket would have many uses in a building emergency. But after a little reflection (pun intended <img src="images/graemlins/smirk.gif" alt="" />), I've thought of two possible scenarios.

One, an emergency evacuation in winter where one is unable to grab one's coat. Still, warm shelter is minutes away, even if a large area of downtown Chicago is under blackout, like during the great flood several years ago.

Two, one could get trapped in the building without heat for an extended period of time. I guess that would be possible and a welcome source of comfort.
