I would suggest using carpeting. This can be purchased in squares for
easy removal and in anti-static versions. The benefit is that the metal
filings will be caught in the carpet fibers (hopefully) long before they get
near the magnet.
One concern is the cleaning crew. However, I don't see that there is any
additional risk of a vacuum cleaner vs. a floor polisher. Normally, these
crews are prevented from cleaning in a magnet lab anyway.
We have had carpet in our Applications Lab for over 11 years and have
been pleased. The added benefit is sound absorption.

We are about to open a new NMR lab which is a short distance down the
hall from a machine shop. My concern is that small metal filings will
cling to the shoes of those walking past the machine shop and find their
way into the lab and inevitably the magnets. A colleague of mine
suggested that I buy some magnetic sheeting (used commonly for signs for
cars etc..) as a foot mat near the entrance to help pull the filings off
shoes. Have any of you used such things? I have heard that tacky mats
can be high maintenance so I would like to avoid them. Are their any
other suggestions for this concern?
