d) Pool basin. Matte white affords the best visibility and
strongest safety factor for the pool basin lining. Light blue will enhance
water color and help camouflage blemishes caused by water impurities but it
will lessen the clarity of underwater markings. Underwater markings should
be a dark blue (cobalt) or black.
e) Pool deck. Avoid heavy or dark color tones for the field. A
dark blue accent band at the gutter creates both a safety line and also adds
a touch of natural color to the water.

Signs and Markings. Water survival facilities are typically
combined with physiological training facilities as aviation survival training
centers. See paragraph 4.2.2.6 for basic data. Safety reinforcement is a
primary purpose for signs in a water survival facility.
a) All variations in pool depth of one foot (300 mm) should be
marked on the pool deck. Markings may also be located on the adjacent walls.
b) Pool Deck. Bulletin boards are especially important in
training facilities to control clutter and readily accommodate changing
information throughout the building. Provide tack board surfaces or similar
surfaces for unanticipated messages, signs, posters, announcements, etc. at
the high traffic area of the pool deck.
c) Pool Rules. Consult the pool user for listing of rules and
show sign in design drawings. Include sanitary, safety, and emergency
information.
d) Operational Instructions. Instructions, including the valve
schedule, must be encased in a waterproof covering and permanently posted on
the equipment room wall.
5.2.2.7
Windows and Natural Lighting. Consider windows, monitors, and
clerestories for internal diffused natural light. Skylights are not
permitted. Natural light is highly desirable. Light monitors, light wells,
and clerestory units should be used to provide a majority of light required
for daytime use. In the pool area, locate fenestration to avoid reflected
glare from the water surface, which can prevent instructors from seeing the
pool bottom; therefore, do not locate glazed areas on the wall directly
opposite instructor stations. Specify corrosive resistant frames such as
aluminum and use hardware such as brass, bronze, or stainless steel within
the pool enclosure. Seal window frames to prevent moisture migration.
Natural light should be concentrated on the ceiling or wall areas toward the
sides and behind the instructor stations. Since glazed areas attract
condensation within the pool enclosure, use double-glazing or gutters to
collect condensation. Consider, as an option, a 1/2" thick heat treated
glass underwater observation window.
Use of interior view windows should be restricted due to the
condensation problems.
5.2.2.8
Doors and Hardware. Locate a grade-level, 6 feet (1800 mm) wide
doorway for maintenance entrance to the pool in addition to any removable
panels or 14'-0" high roll-up steel door for training device installation and
removal. Specify tempered glass and corrosive resistant door frame and
hardware such as brass, bronze, or stainless steel for use within the pool
