Abstract:
A comprehansive methodology has been developed for
obtaining and using smoke toxicity data for fire hazard
analysis. The methodology comprises: determination
that the post-flashover fire is the propert focus of
smoke inhalation deaths; criteria for a useful
bench-scale toxic potency (LC50) measurement method; a
method which meets these criteria, especially validation
against real-scale fires; a computational procedure for
correcting the results for the CO levels observed in
real-scale post-flashover fires; procedures for reducing
the usage of animals and broadening the applicability of
data by interpreting gas measurement data using the
N-Gas Model; and a procedure for identifying whether a
product produces smoke within the ordinary range of
toxic potency for post-flashover fires. The method is
currently being developed for standardization by the
National Fire Protection Association and the American
Society for Testing and Materials.
