Definition of a compartment

[Tom Sutton]

Phoenix that is exactly what I did those many years ago but it’s how I produce a solution that is in dispute. I would use TD, to determine if I could reach a place of relative safety then to place of ultimate safety without putting any occupants in serious danger. Now I could use ASET to determine the time but then I would convert it to TD. But I have been told this is wrong and I should use ASET/RSET but without a computer and fire model I still don’t see how I can apply it to an existing building when on the hoof?

Incidentally I fully agree with the flow chart Fig 3 page 59 in BS 9999.
