Hangars 1106, 1166, 1176 And Building 1178
Mcconnell Air Force Base, Kansas
Poole Fire Protection was the fire protection and life safety consultant for the McConnell AFB in Wichita, Kansas. A fire protection study was conducted for Hangars 1106, 1166 and 1176, as well as Fire Pump Building 1178. The project consisted of a study to determine the existing conditions and to support the preparation of contract drawings and specifications, design analysis and detailed construction cost estimate for the Corrosion Control Phase I at McConnell AFB, KS.
The study consisted of flowing the AFFF foam systems in hangar 1166 and 1176 and an evaluation of the overhead sprinkler system piping and oscillating monitor nozzles in Hangars 1106, 1166 and Hangar 1176. Complete testing of the fire alarm and detection systems, including the heat detection and the UV/IR detection, for each of the three hangars was also conducted. A cost estimate was provided for the recommended work.
A summary report was developed based on the testing. Poole Fire Protection provided a list of recommended corrective actions that would bring the systems into compliance with the applicable NFPA codes and standards along with Air Force criteria. The study concluded that the AFFF sprinkler system in Hangars 1106 and 1176 should be replaced with a new high expansion low-level foam system and wet pipe sprinkler system in accordance with ETL 02-15.
Hangar 1166: Testing of the AFFF system was conducted to verify that the control valves and proportioning equipment functioned properly and would produce 3% AFFF solution. The position and operation of the oscillating monitor nozzles was also verified. The services also included testing the quality of the AFFF foam concentrate within the storage tank. The results showed that the AFFF sprinkler system did not have to be replaced and the system only required minor repairs.
Hangar 1106: A dedicated, high expansion foam concentrate supply was recommended for this hangar. This allows the hangar to stand alone from a fire protection standpoint taking away its reliance on the common foam supply provided by the pumping system within Building 1178. Poole Fire Protection reviewed the shop drawings for the high expansion foam system installation, modifications to existing sprinkler system (converting the AFFF sprinkler system to a wet pipe sprinkler system) and modifying the fire alarm system in the hangar.
Hangar 1176: It was determined that a dedicated, high expansion foam concentrate supply should be provided for this hangar. This allows the hangar to stand alone from a fire protection standpoint taking away its reliance on the common foam supply provided by the pumping system within Building 1178.
Building 1178: Poole Fire Protection recommended that providing a dedicated foam concentrate supply to Hangars 1106 and 1176 would allow the existing AFFF foam concentrate tank and pumping system in Building 1178 to be removed. Due to the limited maintenance performed on the diesel engines, Poole Fire Protection also recommended that a detail servicing of each diesel engine be performed by a qualified diesel mechanic to ensure that the engines are properly maintained and provide reliable service.
