Guest, I share everyones concerns regarding fire safety, I work in the healthcare sector, our life risk is very high and we have fire risk assessed everything in sight. I was an operational firefighter for 28 years in various spheres including Met brigades and smaller, I have inspected and granted licenses to fire services all over, so I know a bit about fire risk assessment. My problem with your question is that you are confusing fantastic probabilities with realistic possibilities, simple risk management solutions will sort out your problems, if people are in the tower and there's nobody in the main body of the church then the management of the church are in breach of Management Regulations, Fire Precautions (Workplace) Regs and loads of other stuff including H&S Act, but thats over 30 years old now and probably doesn't count(!). Ever heard of Building Regs and travel distances, what about compartments and dead end situations et al. Papal immunity is no defence in court as far as I am aware, but I'm willing to be correted on that.
