I had a quick look at the paper and although I may have missed it, it doesn't mention the problem with bugs breeding in the base of the Dyson type hand dryer.
It talks about the risks from paper towel waste, but try swabbing around the drain hole of the Dyson - it will scare you. If you think about how they work, all of the water and bugs from the hands are forced down to the bottom surface of the drier. If you miss the drier from the cleaning and sanitising programme you can have a big problem.
Anybody got any information on the Dyson/UV combo?
