Fire experiments were conducted in a simulated kitchen using an electric range produced data on pre-ignition signatures and potential protective triggering actions and compared nuisance alarm scenarios to pre-ignition scenarios. This session will address the research findings, including the following: CO and smoke obscuration as individual parameters do not accurately indicate an impending fire event; oscillations in smoke measurements prior to ignition appear to be an indicator of an impending fire event; and a technique to generate steam to determine smoke alarm sensitivity to moisture vapor was demonstrated and could be developed into a standard test procedure.
