If water spray or automatic sprinkler protection is used for
building protection, a discharge density of 8.2 L/min/m (0.20 gpm/ft) must be
used over the exposed surface.
6-27.2.2.2.3.1.2
The water supply must be adequate for 2 hours and must
include a hose stream demand of 1900 L/min (500 gpm).

Equipment.
6-27.2.2.2.3.2.1
For multiple transformer installations the water spray system
must be designed based on simultaneous operation of the water spray systems
for the adjacent transformers.
6-27.2.2.2.3.2.2
Design the water spray system to provide a density of 10.2
L/min/m (0.25 gpm/ft) over transformer surfaces, except areas under the
transformer in accordance with FM Global Data Sheet 4-1N, Water Spray Fixed
Systems.
6-27.2.2.2.3.2.3
When the ground around the transformer is non-absorbing,
water spray must be provided at a density of 6.1 L/min/m (0.15 gpm/ft) for the
diked area or for a distance of 3 m (10 ft) from the transformer in all directions.
6-27.2.2.2.3.2.4
Components of the water spray system, such as piping,
spray nozzles, and other components must be a minimum of 45.7 cm (18 in) from
the transformer.
6-27.2.2.2.3.2.5
Piping must not pass over the top of the transformer or be
exposed by tank relief vents.
6-27.2.2.2.3.2.6

TRASH COLLECTION AND DISPOSAL FACILITIES.
6-28.1
Central Trash Collection and Dumpsters. Place central trash
collection units and dumpsters 15 feet (4.6 m) or more away from wood frame or
metal buildings or from openings in masonry-walled buildings.
6-28.2
Collection, Baling, and Storage Rooms. Use 2-hour fire resistive
construction for collection, baling, and storage rooms and protect with automatic
sprinklers.
6-28.3
Trash Chutes. Equip trash chutes in buildings with automatic
sprinklers. In non-sprinklered buildings, trash chute sprinkler systems may be
connected to the domestic water system.
6-29
PROTECTION OF ELEVATOR MACHINE ROOMS AND
HOISTWAYS.
