Air on earth is ~78% nitrogen by volume (and ~75% by mass), whereas moon base air would be 100% oxygen. There seems to be a couple of problems with this:
1.) At 100% atmospheric oxygen, clothing and hair (and lots of other things I'd guess) become highly flammable, even explosive.
You are through to the final round of a game-show and have a chance to win a car which is hidden behind one of three doors. Behind the other two doors are goats.
You must choose one of the doors. The host then opens a different door to the one you selected to reveal a goat, leaving only two doors. You then have the option to stick with your initial choice, or switch to the other unopened door.
So, assuming you prefer cars to goats, what is the best strategy to adopt? :
a.) always stick with your initial choice b.) always switch c.) it doesn't matter
What I really like about this puzzle is that just about everyone who sees it knows the answer staight away, is absolutely certain that they're right, and is completely wrong.
(the subject line is taken from the title of the book where I first read this.)

Perhaps not many road workers get killed, but perhaps that's because they don't work at the highest risk times e.g. during the day. But then you have to pay night-shift wages, and avoiding these could help make the idea economic.

2.) People aren't designed to breathe pure oxygen for extended periods. While it's essential for life, it's also rather toxic - http://en.wikipedia.org/wiki/Oxygen#Precautions
So, unless there's another element up there to dilute the oxygen down, you'd still need to take all the nitrogen you need with you.
