A comprehensive methodology has been developed for
obtaining and using smoke toxicity data for fire hazard
analysis. This description of the methodology comprises
(1) determination that the post-flashover fire is the
proper focus of smoke inhalation deaths; criteria for a
useful bench-scale toxic potency (LC,,) measurement
method; (2) a method which meets these criteria,
especially validation against real-scale fires; (3) a
computational procedure for correcting the results from
the bench-scale test for the CO levels observed in
real-scale post-flashover fires; (4) procedures for
reducing the usage of animals and broadening the
applicability of data by interpreting gas measurement
data using the N-Gas Model; and (5) a procedure for
identifying whether a product produces smoke within the
ordinary range of toxic potency for post-flashover
