Well, it's an important point that Jenny Rathbone makes, Llywydd. Of course, were the outcome of the TAC review to be that ozone cleaning machines have a part to play in the school context, then they would have to be properly prepared, and that would include the training of staff to make sure they can be used safely and effectively. School cleaning staff already use sophisticated equipment in many of our schools, but they only do so because they've been properly prepared and equipped for that task. I'm quite sure that if, and it is a very open question—if the technical advisory cell do conclude that this new innovative technology can have a more widespread use, then making sure that it is deployed safely and with all the training that will be needed will, I'm sure, be part of the advice that they will give us.
