(a)
Sprinkler Protection.
(1) If the facility
being constructed includes the installation of automatic sprinkler protection
which is proposed to be used in lieu of temporary protection, the installation
shall closely follow the construction and be placed in service as soon as
applicable laws permit following completion of each story.
(2) During demolition or alterations,
existing automatic sprinkler installations shall be retained in service as long
as reasonable. The operation of sprinkler control valves shall be permitted
only by qualified persons. Modification of sprinkler systems to permit
alterations or additional demolition should be expedited so that the automatic
protection may be returned to service as quickly as possible. Sprinkler control
valves shall be checked daily to ascertain that the protection is in
service.
(3) During the
construction of a building and until the permanent fire extinguishing system
has been installed and in service, fire protection shall be provided in
accordance with these orders.
(b) Standpipes.
(1) In all structures in which standpipes are
required, or where standpipes exist in structures being altered, they shall,
unless replaced by temporary construction protection, be brought up as soon as
applicable laws permit, and shall be maintained as construction progresses in
such a manner that they are always ready for fire protection use. The
standpipes shall be provided with Siamese fire department connections on the
outside of the structure, at the street level and shall be conspicuously marked
and accessible. There shall be at least one standard hose outlet at each floor.
These installations, when planned as part of the permanent installation, shall
meet the applicable requirements of Articles 158 and 159 of the General
Industry Safety Orders.
(2) Every
building six (6) stories or more in height shall be provided with not less than
one operable standpipe. Such standpipes shall be installed when the progress of
construction is not more than 50 feet in height above grade. Such standpipes
shall be provided with fire department outlet connections at accessible
locations adjacent to usable stairs. Such standpipe systems shall be extended
as construction progresses to within one floor of the highest point of
construction having secured decking or flooring.
Where permanent fire protection equipment is required by
local jurisdiction, it may be used during construction provided it is
constructed concurrently and progressively with the structure and is maintained
operational and accessible.
(3) Every floor shall be provided with not
less than one 2 ½ -inch valve outlet for fire department use. Where
construction height requires installation of a combination standpipe, fire
pumps and water connections shall be provided to serve the standpipe.
NOTE: For specific requirements for portions of the fire
protection system not contained in these orders, refer to Article 158 of the
General Industry Safety Orders or consult with the local fire
authorities.
(4) Temporary
standpipes may be provided in place of permanent systems if they are designed
to furnish a minimum continuous flow of 75 gallons of water per minute at 50
pounds per square inch pressure with a standpipe size of not less than 4
inches. All outlets shall be not less than 2 ½ inches. Pumping equipment
sufficient to provide this pressure and volume shall be available at all times
when a combination system is required.
(5) Standpipe systems for buildings under
construction, if a part of the permanent system, shall be installed as required
for permanent standpipe systems and meet the applicable requirements of
Articles 158 and 159 of the General Industry Safety Orders.
