This is an old topic but as I have just come across a related issue I thought I'd throw one into the mix. An external escape route outside a building (rear garden area of a residential care home) which passes several windows which are clearly not fire rated. As it is a fairly narrow passageway it is not possible to move away from the windows any reasonable distance. This, in my opinion, makes that escape route untenable if the status quo remains regarding the glazing. This route is the only way to leave the garden area unless you re-enter the building on the ground floor which would then allow you to exit by an alternative route.
The external fire escapes which lead to this garden area would only be used as a last resort as from the FRA the normal method would be down the internal staircase to the internal assembly point. Upgrading the glazing makes the problem go away but, of course, has a significant cost attached. It seems counter-intuitive to advise people who do use the external fire escape to re-enter the building on the ground floor in order to avoid passing the 'suspect' glazing ?
Any thoughts ?
