  1. THE INSTITUTION OF FIRE ENGINEERSUnited States of America Branch Fire Service Deployment: Meeting the Standards of Cover Performance Criteria Indianapolis, April 2002

  2. FIRE DEPARTMENT RESPONSE TIMES What would it take to make a difference?

  3. John R. Waters, CFPS, EFO • Chief Fire Marshal • Director of Safety and Codes Enforcement • Upper Merion Township, PA

  4. NATIONAL FIRE ACADEMY Executive Fire Officer Program

  5. Why take the time to study them? RESPONSE TIMES

  6. response times translate to travel distance travel distance translates to number of stations number of stations translates to $$$$$$$$ Volunteer vs. Career also translates to $$$$$ BUDGETS!

  7. It doesn’t matter who provides the service. • proprietary • by contract • response times changes impacts budgets

  8. UNITED STATES FIRE ADMINISTRATION1987 “The United States has one of the highest fire death rates per capita in the world.”

  9. JOHN HALL & ARTHUR COTE 1997 “As a nation, the United States appears to do a better job in protecting property than protecting its citizens, at least compared to other fully industrialized democracies.”

  10. NFPA Standard 403 - Aircraft Rescue & Firefighting Services(1996) “The principle objective of a rescue & firefighting service is to save lives. ...Demonstrated response time to any point on the operational runway shall be 2 minutes or less....”

  11. Fire Incidents vs. Fatalities

  12. Fire Incidents vs. Injuries

  13. Fire Statistics% Residential

  14. George Miller (1999) “…while the overall number of home fire deaths dropped in 1997, the percentage of home fire deaths rose…we’re winning the battle but losing the war.”

  15. PREVENTING RESIDENTIAL FIRE FATALITIES & INJURIES IS THE KEY Is this news?

  16. Benjamin Franklin (1770) “It appears to me of great importance to build our dwelling houses, if we can, in a manner more secure from fire”

  17. 1st National Fire Prevention Convention (1913) “At the outset of the work we established a statistical table of fires, returned monthly by the fire marshals; and for two years that table has read exactly alike each month and, at the end of the year, totals up the same percentage of figures, with the astounding result that 60% of the fires occur in the homes of people.”

  18. America Burning (1973) Residential fires account for about half of all fire deaths and a third of all property loss. The structures in which Americans live must be the prime focus of a national effort to reduce fire losses.”

  19. M. Karter (1993) “If we examine deaths by the type of properties in which they occurred, we find that the increase in civilian deaths was due in large part to a rise in deaths in residential properties…with home fire deaths accounting for 78.4% of all fire deaths, residential fire safety initiatives remain the key to reduction in the overall fire death toll.”

  20. Fatalities by type of residential use

  21. Injuries bytype of residential use

  22. Yet, in 1998, there were no performance standards for fire department response to house fires! NFPA 1710 Committee appointed - January 1999 1st Meeting - February 1999 Adopted - May 2001

  23. NFPA Standards 1710 & 1720(2001) Deployment Standards Standard 1710 - Career Fire Departments Standard 1720 - Volunteer Fire Departments

  24. A Philosophical Question Compartment fires, do they differ when the structure protected is served by career or volunteers? If not, why two standards?

  25. Fire Department Response Times RESEARCH QUESTIONS: • At which point does a fire in a structure become deadly? • What would it take for the fire department to respond and intervene prior to that point?

  26. 1st Research Question • At which point does a fire in a structure become deadly?

  27. James Milke (1984) “Flashover is considered the point of transition from a ‘small’ fire to a ‘large’ fire involving all objects in the room. Once a fully developed room fire exists, life safety for occupants within that room is no longer of concern because the room is obviously untenable after flashover.”

  28. Richard Bukowski & Richard Peacock (1995) “The occurrence of flashover within a room is of considerable interest…it is perhaps the ultimate signal of untenable conditions within the room of origin as well as a sign of greatly increased risk to other rooms within the building.”

  29. T.T. Lie (1997) “Thus the time interval between the start of the fire and the occurrence of flashover is a major factor in the time that is available for safe evacuation of the fire area.”

  30. John Hall (1998) “The majority of people killed in home fires (51.5%) are killed in a room other than the room of origin by a fire that spreads beyond the room of origin, which suggests flashover in the room of origin.”

  31. Victim Location1994-1998

  32. WHAT IS “FLASHOVER?” A stage in the development of a contained fire in which all exposed surfaces reach ignition temperatures more or less simultaneously and fire spreads rapidly throughout the space. NFPA 555 (1996)

  33. Richard Custer (1997) • Triggering conditions for flashover • temperature of upper gas layer of 600C • radiant flux of 20kW/meter2

  34. How long to flashover?

  35. National Bureau of Standards (1980) • < 4 minutes • heavy flame pouring our the full height of doorway • 6 minutes • average gas temperature at 700C

  36. National Bureau of Standards (2001) • 2 minutes 12 seconds • living room flashes over

  37. Fire Power (1986) first flame to flashover took only 3 minutes 41 seconds

  38. Fire:Countdown to Disaster first flame to flashover took only 2 minutes 12 seconds

  39. Institute for Research in ConstructionFire Evaluation and Risk Assessment System Modeled restaurant kitchen fire flashover occurred in 4 minutes 30 seconds

  40. Flashover Time (average) • 4.3 minutes • It is interesting to note, that the for the purpose of NFPA Standard 1710, the committee used the standard time-temperature curve, as it relates to flashover, as the basis for fire department response times..

  41. 2nd Research Question • What would it take for the fire department to respond and intervene prior to flashover?

  42. Fire Department Response Time(Traditional)(Total) • ignition and pre-burn • smoke detector activates and sends alarm • alarm arrives to central station & is processed to dispatch center • dispatch center processes alarm • dispatch • turn-out time • travel time • set-up time

  43. Alarm to central station & transferred to dispatch • 15 seconds to arrive • 30 seconds to process • TOTAL - 45 seconds

  44. Dispatch Time (average) • 56 seconds

  45. Turn-Out Time (average) • leaving the fire station • staffed - 57 seconds • unstaffed -184 seconds • NFPA 1710 allows 60 seconds for turn-out

  46. Travel Time • from fire station to arrival at fire scene • NFPA 1710 defines this as response time • from time apparatus clears the station to arrival on scene • 4 minutes for 1st unit • 8 minutes for balance of 1st alarm

  47. Set-Up Time • arrival at fire scene • disembark apparatus • pull hoseload from apparatus to front door • charge hoseline • don SCBA masks • advanced hoseline into the building • apply water

  48. Set-Up Time (average) • 98 seconds

  49. Compare • average time to flashover - 4.3 minutes • average FD response time • not including detection time • not including travel time • staffed 4.2 minutes • unstaffed 6.3 minutes
