I understand your dilema as an enforcement officer,and the lack of guidance from either HQ or the government .What has your line manager said? :-(
The government has given guidance, eleven volumes of it. That is the government position, carefully written, endlessly re-written, checked word for word by a team of professional stakeholders including the CBI, HSE, CFOA, HMI, FSB, someone representing Sainsburys (can't remember that abbreviation), FBU, and ultimately, as WB says, a team of fire consultants, (most of whom have sensibly buggared off to Australia now) and of course, the BRE who actually did write the sleeping guide. After all that they were finally signed off by the ODPM and the last standing HMI, Geoff Bowles who dedicated his last two years to trying to get them right.
They were painfully aware that old buildings could never achieve modern standard compliance and consequently gave advice on other ways of improving the fire safety in premises such as this one, which seem pretty unsafe to me!
Upgrade the doors and retro fit sprinklers. (Or water mist, or as I saw in a garage once, copper piping with nail holes punched at suitable intervals).
Alternately we could wash our hands, adopt the 'crash dummy' test and put an appropriate number of little fire engine signs in the entrance porch and let the public decide if they really want to pay money to sleep in a one-fire engine hotel rather than a five-fire engine hotel.
Lots of states in the good 'ol USA prompted sprinkler fitting in hotels by refusing to let federal employees sleep anywhere else.
