Fire Safety Engineering Design of Structures

Certainly within the UK for a long period, with the possible exception  of the
period 1939–1945 28during the Second World War29, there have been  very few,
if any, recorded cases of death of the occupants in a fire  caused directly by
the collapse of the structure. There have been  unfortunate cases, however, of
the fire fighters being trapped by a  collapse of the structure, well after the
completion of occupant  evacuation. This relatively low incidence of deaths
resulting from  collapse does not imply that structural integrity 28load-bearing
 response29 is unimportant, but is rather a testimony to the soundness of 
structural design, detailing and construction over that period. It has  already
been noted that the general cause of deaths is asphyxiation,  i.e. being
overcome by smoke and gases, or by being trapped and then  being unable to
escape and then being exposed to the effects of heat. It  is therefore extremely
important to consider all the issues which can  play a part in ensuring life
safety in a fire affected structure
