I would have thought the risk to life was obvious? I am sorry i have not made it a simple request for info but if you had say 15 members of the public at the top of a tower with only one escape route and a fire started the ground floor, how would you get the people out ? My question is to professionals that have carried out assessments what have they done, restricted use, carried out upgrading and other contol measures etc.
Do you know of a church where 15 members of the public assemble in a tower at times when there is no-one else in the building to give warning in case of fire? I was a chorister in my early years and have been organist at several different churches since. As organists are every bit as proud of their anoraks as fire safety enthusiasts, you will no doubt appreciate that I have visited hundreds of churches. I can't think of any (apart from some of the major cathedrals/minsters ) where this would even be possible.
Much more of a problem are the evangelical/charismatic Christian groups and some mosques which regularly cram large numbers of people into premises with hopelessly inadequate MOE. We had a report recently of a mosque that regularly attracted 250 people that only had one door - and that wasn't a final exit.
