A fair point Neil, well made (even after a few beers (or red wine is it?)
I think that the enforcement notice would only be likely to be served as a result of continuous none compliance. Although I couldn't envisage it getting to that stage, if you follow enforcement through the logical process you would end up at an Enforcement Notice by default.
Two different scenarios:
1. Two fire doors leading from a room onto seperate escape routes in a normal/low risk building. If this room is mirrored on each floor, then by wedging a fire door open onto one of the escape routes only, would people be put at risk of death or serious injury in case of fire? I'd say probably not, as a fire is unlikely to start in the first place and if it does then they have an alternative escape route that they can use.
2. A single fire door protecting a single wooden staircase at ground floor level in an anorak factory, where they are using open flame heaters on the ground floor to keep the place warm in the winter i.e. high risk. If this door was wedged open, then in the event of a fire (which is much more likely due to the conditions) would it place relevant persons at risk of death or serious injury from fire? Absolutely!
1 - non compliance (a breach), 2 - non compliance (a breach) and also an offence. As always in my opinion.
A question for you in return. If you were to enforce this particular example i.e. the fire door being wedged open, which Article of the FSO would use?
