Unfortunately, it was written with hospitals in mind and although it causes a problem outside of the hospital - is it another one of those laws that are currently waiting to be tested outside of the hospital environment? I know a few times I've mentioned the word 'consent' and whether thats verbal, written or implied (i.e. putting your arm outtt when a dr/nurse approaches you with a BP cuff) surely it's all down to the consenting individual and for the handler not to use the material for any other usage than stated, i.e. training their dog???
Of course I may stand corrected here - but as long as you respect the consentee's wishes and you look after the material, what harm can be done apart from developing a worthwhile skill you wouln't otherwise have the opportunity to do so?
4 Obtaining scientific or medical information about a living or deceased person which may be relevant to any other person (including a future person).
The above is from the poseted reply from Willy7474, surely the material will be classed as scientific information which will be relevant to any other person in the future - you are actively training a dog to identify a specific scent to aid further future developments?
Really a grey area - but any info I'll up-date you
Maybe a law waiting to be tested!
