Analysis of Performance
This measurement can have significant variability because a small number of incidents may change the percent of success dramatically. In some cases, fires which have grown significantly before the 9-1-1 emergency call is received will be well beyond the control of emergency personnel before they arrive on scene. In the future, policymakers may wish to consider the increased use of the fire code to limit fire spread through the use of building sprinklers. In Q3 2013, several shed fires, classified as loss of the full building of origin, affected the performance on this metric.
This measure relates to the ability of on-scene firefighters and building sprinklers to prevent fire flashover and the spread of a structure fire.
Why Is This Important?
Flashover is the stage of a structure fire when it becomes extremely dangerous to occupants, structures and firefighters. During a flashover, temperatures and conditions are intense and an entire room can burst into flames, causing a fire to spread to other parts of the structure. By containing a fire to its room of origin and delaying flashover, firefighters can buy several minutes, which may be critical. Delaying flashover allows more time to complete a search and rescue of the burning room or allow a firefighter to go above a fire to rescue a trapped victim. Delaying flashover and fire spread can limit fire loss and injuries to occupants and firefighters.
City Organization Impact on Performance
High - PFA's ability to influence the fire containment to the room of origin is rooted in effective firefighter training to attack fire upon arrival, efficient response times, education and outreach to the community on fire safety practices, and the mandatory use of fire sprinklers in some buildings to limit the spread of fire.
