Fire Resisting Furniture for within a Protected Route

[Phoenix]

I'd have to say that I don't think 'spare' is the right term - discounting staircases gives you the resilience in your evacuation strategy that I was promoting earlier. 

That's one thing I would agree on.  No fire safety precautions are ever 'spare'.  Worse still, sometimes people use the word 'redundant'.  Sometimes fire safety features can be removed or left out and the remaining fire safety features will keep the building safe under normal circumstances.  But it is our responsibility to foresee and predict the consequences of those circumstances that are not normal which we know all buildings are subject to at some time during their life.
