LEVEL OF SERVICE STANDARDS (*) The State Legislature in RCW. 52.33.010 communicates its intent for fire departments to establish Level of Service Standards that permit first responders to arrive in time to prevent "brain death" as it relates to EMS; and to prevent "flash-over" as it relates to fire suppression. The Legislature further acknowledges in RCW. 52.33.020 the following benchmarks in its definitions section relative to these two critical emergency events: Brain Death: As defined by the American Heart Association, means the irreversible death of brain cells that begins four to six minutes after cardiac arrest. Flash-Over: As defined by the National Institute of Standards and Technology, means when all combustibles in a room burst into flame and the fire spreads rapidly. * Flash-Over is dependent on many factors, (fuel load, oxygen supply, size of room, etc.) but is generally recognized as a likely event from 7 minutes to 12 minutes after ignition occurs. Consistent with the Legislature's intent the following Level of Service Standards are established for Fire Departments within Pierce County, relative to impact mitigation: TOTAL RESPONSE TIMES (In Minutes) * Response time includes 1:20 minute Turnout time Category Unit Second Unit Balance of First Alarm Typically, an incorporated area or an unincorporated area with a population of over 30,000 and/or a population density of 2,000 people per square mile (or generally within the approved urban growth area): 6:32 11:44 11:44 RURAL 1: An incorporated or unincorporated area with a population between 10,000 and 29,999 and/or a population density of 1,000 to 2,000 people per square mile: 7:50 11:44 14:20 RURAL II: An incorporated or unincorporated area with a population of less than 10,000 or with a population density of less than 1,000 people per square mile: 14:20 19:32 19:32 * To meet standards, the total response times must be achieved on 90% of the responses within a jurisdiction.
