Perhaps Messy's comments gets to the real point, who actually 'owns' the Fire Risk Assessment? We, collectively, give the best of our competent advice based on British Standards, and European Standards, and this guidance document ,and that published information, but if the 'owner' chooses to ignore this, surely it is only the Courts who will actually decide if the 'owners' decisions are wrong. And the 'owner' will only end up in Court if an Enforcing Authority consider the departure from normally accepted customs and practices to be an offence. Painting fire extinguishers a non-standard colour would be open to much 'will we, won't we' discussion within Enforcing Authorities before the topic darkens the doorstep of a Court. So, assuming the correct type of extinguishers are in place, in sufficient numbers, with instructions and all necessary labelling legible, does the colour change cause enforcement action, because it is 'different' if the 'owner' decides to do their own thing?
