WHAT THESE NUMBERS MEAN FOR YOUR FAMILY
HOUSE FIRE
A room reaches flashover in 3–5 minutes. Toxic smoke fills the home in 2–3. Whether your family escapes is decided almost entirely before the first truck arrives.
CARDIAC ARREST
Survival drops 7–10% per minute without CPR. After 10 minutes untreated, odds are poor. Your EMS response time shows exactly how critical in-home CPR training is.
VOLUNTEER DEPARTMENTS
Volunteers drive to the station before the truck can leave — adding 4–8 minutes on average, more at night or in bad weather. The expected time above accounts for this.
THE GAP THAT MATTERS
Responders are trained for when they arrive. The minutes before they do are your family's responsibility alone. A practiced emergency plan is the only thing that fills this gap.
HOW WE CALCULATE THESE NUMBERS

The times shown are estimates of total response time — from the moment you call 911 to when the first unit arrives at your door. This accounts for every stage in the emergency response chain: call processing, turnout, and travel.

STAGE 1 — CALL PROCESSING

For fire emergencies, NFPA 1710 sets a benchmark of 64 seconds for call processing — from the moment 911 receives your call to the moment the station is toned out.1 We apply ~1 minute for fire dispatch overhead.

For medical emergencies, dispatchers must run Emergency Medical Dispatch (EMD) protocol before the unit is released. This runs materially longer than fire dispatch. We apply ~3 minutes for EMS call processing.5

STAGE 2 — TURNOUT TIME

Turnout time is the interval from when the station alarm sounds to when the apparatus is moving. NFPA 1710 sets the benchmark at 80 seconds for fire and 60 seconds for EMS.1 Real-world performance falls short regularly — career departments met the 80-second standard only 48–66% of the time in documented studies.4 We apply ~2 minutes for fire and ~1 minute for EMS.

STAGE 3 — DRIVE TIME

Drive time is calculated using Google Maps routing from the station to your address. NFPA 1710 benchmarks 4 minutes of drive time for the first arriving engine at 90% of incidents.1 In practice, 34% of large U.S. cities fail to meet this standard,3 and the national 90th percentile for total fire response is just under 11 minutes.4

VOLUNTEER DEPARTMENTS — ADDITIONAL OVERHEAD

Volunteer firefighters must first travel from home or work to the station before the truck can leave. NFPA 1720 sets total response benchmarks of 9 minutes urban, 10 minutes suburban, 14 minutes rural.2 We apply +5 minutes additional overhead for volunteer fire and +7 minutes for volunteer EMS on top of career baselines.4

SOURCES
  1. NFPA 1710 — Standard for the Organization and Deployment of Fire Suppression Operations, Emergency Medical Operations, and Special Operations to the Public by Career Fire Departments. Establishes call processing (64 sec), turnout (80 sec fire / 60 sec EMS), and travel time (240 sec) benchmarks.
  2. NFPA 1720 — Standard for the Organization and Deployment of Fire Suppression Operations, Emergency Medical Operations, and Special Operations to the Public by Volunteer Fire Departments. Total response benchmarks: urban 9 min, suburban 10 min, rural 14 min.
  3. International Association of Fire Fighters (IAFF) — Survey of response times in the 50 most populous U.S. cities. 34% of large city career departments do not meet the NFPA 1710 240-second travel time standard.
  4. U.S. Fire Administration / National Fire Data Center — Structure Fire Response Times. USFA-TR-153. Documents real-world response time distribution, national 90th percentile, nighttime performance gaps, and volunteer turnout time definition.
  5. Emergency Medical Dispatch (EMD) Protocol — International Academies of Emergency Dispatch (IAED). Structured pre-arrival questioning protocol required before EMS unit release.
