Baxpat,
I can see what you are getting at.
There is no substitute for forward planning as far as safety equipment goes, if you haven't got it when you need it, what is the point of having it at all.

Sure, there will be idiots around that like to "play" with fire extinguishers and the like, make it a dismissable offence to do so, after making an example of them.

How would you feel that some other person was badly burned because YOU were "having a bit of fun" the day before with the only means of extinguishing the fire that took hold in a part of the factory?
Doesn't even have to be a fire extinguisher, could be a tool that is used to isolate something in a hurry.

I think a board like this has it's merits, it is gear right where it is needed.
