What does the forum think about the "currency" of risk ratings? How long are they valid for?
There are some buildings where the fire safety is intrinsically less robust than others; for example, ones with single staircase escape. And some uses will attract a higher rating. However we would all probably agree that "management" is the single most important factor.
An IO rates a building then the occupier changes; so much for the risk rating. To be practical, there needs to be some workable system but ratings that incur reinspection in, for example, 10 years give a false sense of security.
Perhaps the management part of the rating should be ignored for ratings over 5 years and the reinspection period based on use and basic physical configuration.
