Current through Register 2024 Notice Reg. No. 38, September 20, 2024
(a) Scope and Application.
(1) Scope. This Section applies to all small
hose, Class II, and Class III standpipe systems.
(b) General.
(1) When standpipe and hose systems are
provided, they shall be designed and installed in an approved manner.
NOTE: For information on standpipe and hose systems
design and installation, consult the National Fire Protection Association's
Standard for the "Installation of Standpipe and Hose Systems", NFPA 14, 2013
edition and/or your local jurisdiction fire
department.
(c)
Protection of Standpipes.
(1) The employer
shall assure that standpipes are located or otherwise protected against
mechanical damage. Damaged standpipes shall be repaired
promptly.
(d) Equipment.
(1) Reels and Cabinets. Where reels or
cabinets are provided to contain fire hose, the employer shall assure that they
are designed to facilitate prompt use of the hose valves, the hose, and other
equipment at the time of a fire or other emergency. The employer shall assure
that the reels and cabinets are conspicuously identified and used only for fire
equipment.
(2) Hose Outlets and
Connections.
(A) The employer shall assure
that hose outlets and connections are located high enough above the floor to
avoid being obstructed and to be accessible to employees.
(B) The employer shall standardize screw
threads or provide appropriate adapters throughout the system and assure that
the hose connections are compatible with those used on the supporting fire
equipment.
(3) Hose.
(A) The employer shall assure that every 1
1/2" (3.8 cm) or smaller hose outlet used to meet this standard is equipped
with hose connected and ready for use. In extremely cold climates where such
installation may result in damaged equipment, the hose may be stored in another
location provided it is immediately available and can be connected when
needed.
(B) Standpipe systems
installed after July 1, 1981, for use by employees, shall be equipped with
lined hose. Unlined hose may remain in use on existing systems. However, after
the effective date of this standard, unlined hose which becomes unserviceable
shall be replaced with lined hose.
(C) Beginning July 1, 1981, the employer
shall provide hose of such length that friction loss resulting from water
flowing through the hose will not decrease the pressure at the nozzle below 30
psi (210 kPa). The dynamic pressure at the nozzle shall be within the range of
30 psi (210 kPa) to 125 psi (860 kPa).
(4) Nozzles. Beginning July 1, 1981, the
employer shall assure that all lined standpipe hose is equipped with shut-off
type nozzles.
(e) Water
Supply.
(1) The minimum water supply for
standpipe and hose systems, which are provided for the use of employees, shall
be sufficient to provide 100 gallons per minute (6.3 l/s) for a period of at
least thirty minutes.
(f)
Tests and Maintenance.
(1) Acceptance Tests.
(A) The employer shall assure that the piping
of Class II and Class III systems installed after July 1, 1981, including yard
piping, is hydrostatically tested for a period for at least 2 hours at not less
than 200 psi (1380 kPa), or at least 50 psi (340 kPa) in excess of normal
pressure when such pressure is greater than 150 psi (1030 kPa).
(B) The employer shall assure that hose on
all standpipe systems installed after July 1, 1981, is hydrostatically tested
with couplings in place, at a pressure of not less than 200 psi (1380 kPa),
before it is placed in service. This pressure shall be maintained for at least
15 seconds and not more than one minute during which time the hose shall not
leak nor shall any jacket thread break during the test.
(2) Maintenance.
(A) The employer shall assure that water
supply tanks are kept filled to the proper level except during repairs. When
pressure tanks are used, the employer shall assure that proper pressure is
maintained at all times except during repairs.
(B) The employer shall assure that valves in
the main piping connections to the automatic sources of water supply are kept
fully open at all times except during repair.
(C) The employer shall assure that hose
systems are inspected at least annually and after each use to assure that all
of the equipment and hose are in place, available for use, and in serviceable
condition.
(D) When the system or
any portion thereof is found not to be serviceable, the employer shall remove
it from service immediately and replace it with equivalent protection such as
extinguishers and fire watches.
(E)
Hemp or linen hose on existing systems shall be inspected for deterioration at
least annually. Defective hose shall be replaced in accordance with Section
6165(d)(3)(B).
(F) The employer shall designate trained
persons to conduct all inspections required under this
Section.
