en ten opzichte van rookmelders is dit ook wel aardig:
Note that the NIST analysis shows how sprinklers and smoke alarms both have an essential role
to play in providing life safety from fires in homes. If smoke alarms are introduced first (which
is the way most people would do it), the NIST study estimates fire death rates would fall by 52%.
Adding sprinklers would further reduce by 63% the 48% of the original death rate that remains,
producing a 30% reduction relative to that original death rate, or a total reduction of 82%. Or, if
sprinklers were introduced first, the original death rate would be estimated to fall by 69%. Then
adding smoke alarms would reduce by 42% the 31% of the original death rate that remained,
producing a 13% reduction relative to that original death rate, for the same total reduction of
82%. What this means is that sprinklers will save many people who would not be saved by
smoke alarms, and smoke alarms will save many people who would not be saved by sprinklers.
