You're mistaken there Neil, I'm afraid. The legal aspect has been touched on, both here and in the earlier threads linked to. frown

But, seeing that you're with us ... what's your own take on all this:- simply following manufacturer' recommendations, ECRI guidelines, national standards (ie, the norms in Saudi Arabia), or what?

Are you happy with the idea of flexibility in setting (and adjusting) PM intervals? You still do PM, I hope! smile

And your second point is a bit nebulous, Mate. We're talking about staffing levels (and now we've drifted off into approaches to PM). The quality of the common or garden biomed tech is taken as a given for the purposes of this discussion!

If you don't inspect ... don't expect.
