For anyone interested in outdoor education, especially nurseries. We run an award winning outdoor nursery in Fife.
We're currently engaged in a dispute with the quango/ regulator over the issue of hand hygiene. Our nursery is fully nomadic, and focusses on child-led play. Because of this we have no regular access to running water. Health Protection Scotland has issued a guideline insisting that soap and running water must be used to wash the children's hands at numerous points during the day - before arrival, before going home, at mealtimes, after (and before) toileting, after sneezing, etc. 
We use gel-impregnated wipes which have the support of leading scientists and are standardly used e.g. in NHS hospitals in Scotland and at other public sites such as those run by Historic Scotland. None of which, it seems, is good enough for the regulators. Our rating has suffered as a result even though the nursery is acknowledged as a UK-leading initiative (first fully outdoor nursery in the UK).
