1 Introduction

Hangar/Building 4247 is located at Keesler Air Force Base (AFB) in Mississippi. The hangar contains fueled aircraft, with the primary function of the hangar being general aircraft maintenance. The hangar was constructed in 2005 and the fire suppression system was also installed in 2005. The aircraft servicing (hangar bay) area is approximately 53,600 square feet (sf).

The fire suppression systems serving the hangar bay consist of five automatic wet pipe sprinkler systems and one high expansion foam system. Water is supplied from two 2,500 gallons per minute electric-driven fire pumps. The pumps are located in the hangar riser room and the water supply for the pumps is from the base water supply distribution. The foam system is activated by manual foam discharge stations or a flow switch on a wet pipe sprinkler system serving the hangar bay. The wet pipe systems are thermally activated. All systems are operational.

At the time of inspection, the installed high expansion foam system and sprinkler systems generally met the Air Force Standard Design Elements as indicated in ETL 02-15.

The fire protection systems and their associated controls are generally being maintained in accordance with the requirements of UFC 3-601-02. The base is currently utilizing both a manual and an automated maintenance record keeping system.

In compliance with the project Statement of Work (SOW), the Hangar Evaluation Installation Report (HEIR) is focused on an evaluation of the fire suppression, controls and detection, pumping, electrical and egress systems supporting the aircraft servicing areas (hangar bays) based on interviews, visual observations and review of available as-built documentation.

Additionally, the evaluation includes review of: systems installed; system deficiencies;

recommended corrective actions; and rough order of magnitude (ROM) cost estimates for the fire suppression system, controls and detection systems, and pumping systems. Costs have been developed for repairs needed to meet required standards, as well as costs to upgrade to Department of Defense (DOD) Configuration Control requirements, Unified Facilities Guide Specification (UFGS) 21.13.12.00.30 (Draft). The ROM costs have been developed using R.S.

Means, information from various vendors and engineering judgment.

This report was prepared by URS as requested by AFCEC in order to evaluate the existing hangar’s condition at the time of inspection. This report recommends the improvements that are needed to bring the existing hangar up to current standards and the draft UFGS. URS is not incorporating any modifications that may have been made since the inspection team visited the hangar.

1.1 Base Provided Documents

The following documents were provided by base personnel for use in evaluating the various systems during inspection:

3 Findings

3.1 False/Nuisance System Activations

Based on discussions with facility maintenance staff, the fire suppression system has had one false activation during the approximate nine-year life of the current systems. On 1 June 2006, a panel malfunction caused the foam system to discharge.

The hangar has not had any previous fire events where the system failed to activate during the approximate nine-year life of the current systems.

3.2 Emergency Shutdown

Based on visual observations, the hangar currently has the capability to abort the system before a false activation, but it does not have the correct valve to stop the flow of foam after an activation.

3.3 Design/Construction

No deviations were noted between the design documents and systems installed; however, during visual inspection of the hangar fire suppression system, deviations were noted between the Air Force Standard Design Elements and installed systems. The isolation valves on the concentrate piping had plastic ties for valve supervision, while the Air Force Standard Design Elements require concentrate valves to be electrically supervised.

3.4 Procedural Issues

None observed.

6.4 Summary of Pumping Systems

The hangar pumping system is not in compliance with the referenced criteria. The implementation of these proposed corrective actions to comply with the required ETL will improve system reliability and improve the overall efficiency of the system.

7 Electrical Systems

The hangar is used for general aircraft maintenance, and all electrical receptacles/outlets were evaluated and found to comply with NFPA 70 (NEC) Article 513 for hazard classification.

Electrical features were evaluated and found to not have the appropriate NEMA rating (4, 4X, 6, 6P) to protect them against hose down and splashing water. See Appendix D – Data Collection Survey, for additional information.

NEMA 1, 2, 3, 7 and 8 enclosures observed in the hangar

8 Life Safety / Egress

Aircraft hangars are typically not designed to accommodate assembly occupancies such as ceremonies and training exercises, and this report is not intended to address requirements for assembly occupancies. The Command should conduct a fire protection/life safety evaluation of the hangar prior to its use for any assembly activity. One example of this requirement is the presence of panic hardware on exit doors. It was noted during the field investigation this hangar does not have panic hardware on all required exit doors.

Egress from the aircraft servicing area is in compliance with Life Safety Code NFPA 101, Section 40.2.6. See Appendix D – Data Collection Survey for additional information. No deficiencies have been identified.

9 Maintenance Review

The fire suppression, controls, detection and pumping systems are maintained by a combination of the Base Civil Engineering Shops and a private contractor. Along with records verification, visual observations of the hangar indicate the records are consistent with the actual facility conditions.

In addition to manual records maintained by the fire protection systems contractor, the base is currently utilizing both an automated and manual maintenance record keeping system. The automated system being used is the Interim Work Information Management System (IWIMS) with its recurring work program (RWP).

Efforts are being made to properly maintain and record the information; however, it was reported during discussions that staffing is not always sufficient to accomplish all required maintenance.

Additionally, maintenance is not always being properly entered in the IWIMS; however, performed maintenance is consistently documented in the form of inspection tags on the valves and inspection stickers on the alarm panels.

The fire suppression systems are being maintained in accordance with the requirements of UFC 3-601-02. Monthly and annual tests records were received for the wet pipe systems. Two-year foam inspections for 2011 and 2013 were received. Semi-annual and annual inspections for the high expansion foam system were also received.

The fire suppression system controls are being maintained in accordance with the requirements of UFC 3-601-02. IWIMS records were received.

The pumping systems are not fully being maintained in accordance with the requirements of UFC 3-601-02. Monthly and two year records were provided, but five year flow test records were not. However, it was indicated by the base the 5-year tests were conducted. It was also indicated a pass/fail rating for the flow tests were not given for each flow test completed.

10 HEIR Conclusion

The hangar egress system has been found to be in compliance with the referenced criteria.

However, the fire suppression, foam controls, pumping and electrical systems are not in compliance with the referenced criteria.

The estimated cost to bring the systems into compliance with required standards and the cost to upgrade the systems to the requirements of UFGS 21.13.12.00.30 (Draft) is summarized below.

More detailed information on these costs can be found in Appendix A – ROM Cost Estimate for Existing Deficiencies and Appendix B – ROM Cost Estimate for Upgrade to DOD Configuration Control.
