The Office of the State Fire Marshal's adoption of this chapter or individual sections is applicable to structures regulated by other state agencies pursuant to Section 1.11.0.
Except as otherwise addressed in this
code, this chapter shall govern the installation of process piping
in or in conjunction with a building or structure located
upon the premises.
It shall be unlawful to install, alter, or
repair or cause to be installed, altered, or repaired process
material piping without first obtaining a permit.
Permits for process piping shall show the total number of
outlets to be provided for on each system and such other
information as required by the Authority Having Jurisdiction.
Fees for process piping permits are included in Table 104.5.
Plans, engineering calculations, diagrams,
and other data shall be submitted in one or more sets with
each application for a permit. The Authority Having Jurisdiction
shall be permitted to require plans, computations, and
specifications to be prepared and designed by a registered
design professional.
Where plans or other data are submitted for review, a
plan review fee shall be paid, as provided in Section 104.3.2.
Process piping shall not be strained or bent,
nor shall tanks, vessels, vats, appliances, or cabinets be supported
by or develop strain or stress on the piping.
Upon completion of the installation, alteration,
or repair of process piping, and prior to the use thereof,
the Authority Having Jurisdiction shall be notified that such
piping is ready for inspection.
Excavations required for the installation of underground
piping shall be kept open until such time as the piping has
been inspected and approved. Where such piping is covered
or concealed before such approval, it shall be exposed upon
the direction of the Authority Having Jurisdiction.
The Authority Having
Jurisdiction shall make the following inspections and shall
either approve that portion of the work as completed or shall
notify the permit holder wherein the same fails to be in accordance
with this code.
This inspection
shall be made after process piping authorized by the permit
has been installed and before piping has been covered or concealed. This inspection shall include a determination
that the piping size, material, and installation
are in accordance with the requirements of this code.
This inspection
shall be made after piping authorized by the permit has
been installed and after portions thereof that are to be covered
or concealed are so concealed. This inspection shall
include a pressure test, at which time the piping shall
stand a pressure of not less than one-and-one-half times
the maximum designed operating pressure where
hydraulic testing is conducted or 110 percent where testing
is conducted pneumatically. Test pressures shall be
held for a length of time satisfactory to the Authority Having
Jurisdiction, but in no case for less than 30 minutes
with no perceptible drop in pressure. HPM drain, waste,
and vent piping shall be tested in accordance with the
plumbing code. Tests shall be made in the presence of the
Authority Having Jurisdiction. Necessary apparatus for
conducting tests shall be furnished by the permit holder.
In addition to the inspections
required by this section, the Authority Having Jurisdiction
shall be permitted to require a special inspector, as specified
in the building code, during installation of piping systems. In
cases where the work authorized was installed in accordance
with plans and specifications prepared by a registered design
professional, the Authority Having Jurisdiction shall be permitted
to require a final signed report stating that the work
was installed in accordance with approved plans and specifications
and the applicable provisions of this chapter.
Process pipe, tubing, and fittings shall comply with ASME B31.3 and shall be installed in accordance with the manufacturer's installation instructions. Materials shall be rated for the operating temperatures and pressures of the system, and shall be compatible with the type of liquid.
HPP supply
piping or tubing in service corridors shall be exposed to view.
HPP piping shall be identified in accordance with nationally
recognized standards to indicate the material being transported.
Liquid HPP piping shall have an approved means for
directing spilled materials to an approved containment or
drainage system.
Liquid HPP waste or drainage systems shall be installed
in accordance with the plumbing code.
Hazardous process supply pipe
shall not be located within exit corridors, within a portion
of a means of egress required to be enclosed in fire-resistive
construction, or in concealed spaces in or above areas not classified as Group H Occupancies, except as
permitted by this subsection.
Hazardous production material piping and tubing
shall be permitted to be installed within the space
defined by the walls of exit corridors and the floor or
roof above, or in concealed spaces above other occupancies
in accordance with Section 1406.2.1.1 through
Section 1406.2.1.6.
Automatic
sprinklers shall be installed within the space unless
the space is less than 6 inches (152 mm) in the least
dimension.
Ventilation at not less than
6 air changes per hour (ACH) shall be provided. The
space shall not be used to convey air from other
areas.
HPP supply piping and tubing
and HPP nonmetallic waste lines shall be separated
from the exit corridor and from an occupancy
other than a semi-conductor fabrication facility classified
as a Group H Occupancy by construction, as
required for walls or partitions that have a fire-protection
rating of not less than 1 hour. Where gypsum
wallboard is used, joints on the piping side of the
enclosure need not be taped, provided the joints
occur over framing members. Access openings into
the enclosure shall be protected by approved fire
assemblies.
Readily
accessible manual or automatic remotely activated
fail-safe emergency shutoff valves shall be installed
on piping and tubing other than waste lines at the following
locations:
- At branch connections into the fabrication area.
- At entries into exit corridors. Excess flow valves shall be installed as required by the fire code.
Electrical wiring
and equipment located in the piping space shall be
approved for Class I, Division 2, Hazardous Locations.
Exception: Occasional transverse crossing of the corridors
by supply piping that is enclosed within the corridor
need not comply with Section 1406.2.1.1 through
Section 1406.2.1.6.
Where hazardous production material gas is used or dispensed and the physiological warning properties of the gas are at a higher level than the accepted permissible exposure limit of the gas, a continuous gas-monitoring system shall be provided to detect the presence of the short-term hazard condition. Where dispensing occurs and flammable gases or vapors are capable of being present in quantities in excess of 25 percent of the lower explosive limit, a continuous gas-monitoring system shall be connected to the emergency control station.
