MIL-HDBK-1027/4A
c) Pool/training. Skylights and clerestories are important
considerations regarding natural illumination.
Where underwater lighting is required, fixtures and lamps should be
selected to provide 100 lamp lumens per square foot (0.9 square meter) of
water surface. The lights should be located 2 feet (600 mm) below the water,
measured to the centerline. Fixtures should be set at an angle of 15 degrees
downward to reduce surface glare. Fixtures should be installed with
sufficient cable to permit repair or re-lamping on the deck of the pool.
Fixtures used for pool surface lighting should be located as
required for maintenance. Lighting fixtures should be directly accessible
from the pool deck or from permanently installed catwalks to facilitate
cleaning and re-lamping. Long life lamps and fixtures designed for corrosion
resistant finishes should be used. Fixtures should be metal-halide for good
color rendition. Use lower wattage lamps to allow dual lighting levels
through switching. Use photocells to turn off lighting when lighting levels
exceed 30 foot-candles.
Refer to Illuminating Engineering Society Handbook for illumination
level recommendations.
5.2.8.3
Lightning Protection. Perform a lightning protection risk
assessment on all aviation training facility types, in compliance with
Appendix I of NFPA-780, to justify lightning protection when required by the
regional Engineering Field Division. Comply with applicable sections of
MIL-HDBK-1004/6.
5.2.8.4
Facility Low Voltage Power. Refer to applicable TFR or Technical
Manual and comply with MIL-HDBK-1004/1 and MIL-HDBK-1004/4. Generally
provide 480Y/277 volt, three phase, four-wire service to the facility along
with dry type transformers to step voltage down for 120, 208 and 240 volt
requirements.
5.2.8.5
Intrusion Detection System (IDS). IDS systems are not normally
required; however, if needed they are procured and installed via contracts
administered by NCIS. Coordinate with NCIS for facility planning, design and
construction schedules. IDS systems including commercial power supply,
utility and control wiring systems are considered personal property. Provide
support system in the construction contract, to include conduit with pull
wire and device boxes. IDS for Marine Corps projects are separately funded
and managed and do not require NCIS coordination. Provide IDS support
requirements and startup specification where required, in accordance with
MIL-HDBK-1012/1.
5.2.9
Fire Protection. Comply with MIL-HDBK-1008C, UBC, and NFPA 99 and
NFPA 101. Classroom facilities for Navy installations are considered
"business" occupancies per NFPA 101. Assembly occupancies, conference rooms
and classrooms with fixed seating and hypobaric chambers require special
attention. Hypobaric oxygen storage requires a dedicated room conforming to
NFPA 55, Standard for the Storage, Use, and Handling of Compressed and
Liquefied Gases in Portable Cylinders. Provide visual fire alarm signals on
a case by case basis, where ambient noise in classrooms can prevent hearing
audible alarms. Requirements for sprinkler systems, carbon dioxide
extinguishing systems, fire alarm systems and protection of electronic
equipment installations, are determined by MIL-HDBK-1008C. Hand held
