Published on

This is class to orient and educate firefighters on the proper response and actions to be taken when responding to fires at buildings equipped with fire sprinkler and standpipe systems. This course is based on the recommendations of NFPA 13E, "Recommended Practice for Fire Department Operations in Properties Protected by Sprinkler and Standpipe Systems", and local fire department protocols.

Fighting Fires in Sprinklered Buildings

  1. 1. Fighting Fires in Sprinklered Buildings NFPA 13E
  2. 2. Types of Sprinkler Systems • Wet-Pipe • Dry-Pipe • Preaction • Deluge
  3. 3. Wet-Pipe System How system works?
  4. 4. Dry-Pipe System • water replaced by air under pressure • air escapes first, valve opens • air-pressure gauge above the valve; water pressure gauge below
  5. 5. Preaction System • dry system • deluge-type valve, fire detection systems, closed sprinklers • system discharges only when smoke/heat device is activated
  6. 6. Preaction System Single-interlock Double-interlock
  7. 7. Preaction System VIDEO
  8. 8. Deluge System • open heads • deluge valve (specific to system sections) • flame/heat/smoke detection devices • manual device
  9. 9. Types of Sprinkler Heads
  10. 10. Identify what types of systems are in each building on the facility.
  11. 11. NFPA 13E Fighting Fires In Sprinklered Buildings
  12. 12. Why sprinklers fail? 1. Closed valve in supply line. 2. Inadequate water supply to the system. 3. Occupancy changes that render system ineffective. How do we mitigate these risks?
  13. 13. Pre-incident Planning 1. Building construction, contents, layout 2. Water supply to system, source/type, flow/pressure, duration of available supply 3. Location of control valves, area controlled, consequence of shutting valve 4. Location of FDC and layout to be used 5. Location of other water supplies 6. Alternate means of supplying water (damaged FDC) 7. Location of spare/replacement sprinklers
  14. 14. Fireground Operations *Sprinkler system should not be shut down 1. supply system (150 psi)
  15. 15. Fireground Operations *Sprinkler system should not be shut down 1. supply system (150 psi) 2. connect other hose streams (use different source) 3. verify that water is flowing to system 4. If not- verify valves are open, verify pump operation (make note of closed valves for investigation)
  16. 16. Fireground Operations 5. If not- verify valves are open, verify pump operation 6. Initiate ventilation procedures 7. Salvage covers deployed to protect property 8. Undertake water removal procedures
  17. 17. Post-fire Operations 1. System should not be shut down until fire extinguished. 2. Shut down sectional valve, not main system 3. Firefighter to remain at valve until overhaul complete. 4. Shut down lines connected to FDC. 5. If only few opened heads, use wedges
  18. 18. Post-fire Operations 6. Conduct routine overhaul; initiate investigation (notify fire prevention) 7. Disconnect hose lines 8. Contact sprinkler contractor; assist in restoring system (building should not be occupied until system restored) 9. Notify fire prevention.
  19. 19. Reports • location of operating sprinklers • number of sprinkler operating • result of sprinkler operation • reason for unsatisfactory operation • employee assigned to • did FD connect to system • unit that connected to FDC • number of lines used • was water pumped into system? how long? what pressure? • valve closed after fire
  20. 20. Reports • number of sprinklers replaced by fire dept. • type of sprinklers installed • was system restored? by whom? • actions taken to restore service • did water supply • fire prevention personnel notified • proper facilities personnel notified
  21. 21. Exercise Given a floor plan, walk through facility and make note of sprinkler system components and connections. Connect to FDC from truck, to ensure proper operation.
