extinguish all non-emergency general lighting from every access door to
the space.
(d) Provide a small red pilot light over the outside of each access
door to the interstitial space indicating when the switched lighting is
on.
(e) Locate exit lights inside the access door to the interstitial space
at a point 1200 mm (4 ft.) after the finished floor and approximately
150 mm (6 inches) horizontally from the access door frame. Provide exit
lights with metal stencil face type to minimize breakage. Provide
additional directional signs, if the path or route to the access
door(s) is particularly circuitous.
(f) Connect all or part of the lighting in Equipment Rooms at the
interstitial floor level on emergency circuits. In the smaller
Equipment Rooms, the emergency lighting should be switched at the doors
as with all other fixtures. In large Equipment Rooms, a few select
emergency fixtures should be un-switched, and the rest switched from
inside the door(s) and monitored by pilot light outside the door(s).
6.17 KITCHEN HOOD
Control lighting fixtures, which are integral with kitchen exhaust
hoods, to operate when the exhaust system for the hood operates.
6.18 POOL LIGHTING
(a) The lighting of therapeutic pools should minimize glare on the
water. Use lighting fixtures mounted above or at a high angle as viewed
from the pool. Do not mount lighting fixtures directly over the pool
unless they can be serviced from above. For underwater lighting, use
low voltage, wet niche type.
(b) Utilize fluorescent, metal halide or deluxe white mercury sources
for reasonable color rendition mounted in moisture-resistant fixtures
above the pool or pool apron. Provide underwater lighting from niches
in pool walls. Refer to Illuminating Engineering Society Handbook for
underwater lighting recommendations. Use wall-mounted fluorescent
fixtures or HID wall packs to light the apron and shield them to
prevent the spilling of glaring light into the pool. Overhead lighting,
which partially lights the pool surface, is preferred.
(c) An illumination level of 430.4 lux (40 foot-candles) minimum is
recommended for the apron. Underwater lights should supplement the
spill light from the overhead apron lighting to provide clear
visibility of persons in the pool.
(d) If the ceiling height is sufficient to avoid bright spots, use
wall- mounted indirect HID luminaries for effective general
