Closing down a hospital is something I'd never done before. One ward at a time, we'd close down, scrub everything twice with bleach, take it all apart, and stash it somewhere else, then strip and wax the floors. Once that was done, we'd refill the ward with all kinds of things that needed to be stored during the sail. Everything was packed or stacked tightly and then tied down with various straps so it couldn't move. The process was hard work, but with a little music and a lot of humour, it was also a fun job.
We scrubbed with a buffer (harder to use than you might think, it takes off in circles around you if you don't hold just the right tilt/lean and pressure)
We dried floors with towels (and may have had towel races and dances etc)
Please don't pack the nurses in!!
