Fire service standards are established by the National Fire Protection Agency (NFPA); NFPA Standard 1710 addresses the performance measure of travel time and sets its standards by percentiles rather than averages. According to NFPA 1710: The fire department’s fire suppression resources shall be deployed to provide for the arrival of an engine company within a 240-second travel time to 90 percent of the incidents; in 2014 SMFD responded to 70% of the incidents within a 240-second travel time. When considering travel time, it is important to understand that travel time is affected by population density, traffic, construction zones, street closures, etc.
