No. Cant be done. You have no history or evidence chain as the FSO just grumbles and pockets the wedges every time he visits.
Slightly disagree there.
The fact is if anything were to occur (for instance the chain smoking patient set fire to his / her bedding - the fire spreads because the door was propped open - people are put at risk ) then the resulting investigation would look at all aggrivating factors. This could include what affect the social worker had.
There's nothing stopping the Fire Authority from obtaining witness statements to say that the social worker asked for the door to be wedged or interviewing the social worker.
Clearly the responsible person should have acted on the situation and looked at installing hold open devices and the like, but that aside, this demonstrates a common problem when inspectors from other authorities insist or compell the RP to do X,Y or Z (sometimes using the bluff and pursuasion act) which unfortunately conflicts with, or places the RP in contravention of fire safety legislation.
The RP is sometimes left being pushed from pillar to post wondering what they should have done differently.
Back to propping open doors - I do agree that 9 times out of 10 removing the wedge is treating the symptom and not the cause.
In Kurnals example wedges are definately unacceptable. But go back to my small low risk office where the staff are sweltering in the heat during the summer months and prop their door open to get a bit of ventilation. So long as the item propping the door was removed when the office is unattended or the fire alarm activates is there really an issue? The Answer is risk assessment!
