assembly shall be constructed of listed components (by a nationally
recognized testing laboratory) and installed in accordance with the
listing.
(II) Special requirements. Finished ceilings may be
omitted in mechanical and equipment spaces, shops, and similar spaces
unless required for fire-resistive purposes.
(iv) Floor, wall, and ceiling penetrations. Floor,
wall, and ceiling penetrations by pipes, ducts, and conduits shall
be tightly sealed to minimize entry of dirt particles, rodents, and
insects. Joints of structural elements shall be similarly sealed.
(v) Cubicle curtains, draperies, and other hanging
fabrics. Cubicle curtains, draperies, and other hanging fabrics shall
be noncombustible or flame retardant and shall pass both the small

for Flame-Resistant Textiles and Films, 1996 edition. Copies of laboratory
test reports for installed materials shall be submitted to the department
at the time of the final construction inspection.
(D) General mechanical requirements. This subparagraph
contains requirements for mechanical systems; air-conditioning, heating
and ventilating systems; steam and hot and cold water systems; plumbing
fixtures; piping systems; and thermal and acoustical insulation.
(i) Cost. All mechanical systems shall be designed
for overall efficiency and life cycle costing, including operational
costs. Recognized engineering practices shall be followed to achieve
the most economical and effective results except that in no case shall
patient care or safety be sacrificed for conservation.
(ii) Equipment location. Mechanical equipment may be
located indoors or outdoors (when in a weatherproof enclosure), or
in a separate building(s).
(iii) Vibration isolation. Mechanical equipment shall
be mounted on vibration isolators as required to prevent unacceptable
structure-borne vibration. Ducts, pipes, etc., connected to mechanical
equipment which is a source of vibration shall be isolated from the
equipment with vibration isolators.
(iv) Performance and acceptance. Prior to completion
and acceptance of the facility, all mechanical systems shall be tested,
balanced, and operated to demonstrate to the design engineer or his
representative that the installation and performance of these systems
conform to the requirements of the plans and specifications.
(I) Material lists. Upon completion of the contract,
the owner shall obtain from the construction contractor parts lists
and procurement information with numbers and description for each
piece of equipment.
(II) Instructions. Upon completion of the contract,
the owner shall obtain from the construction contractor instructions
in the operational use and maintenance of systems and equipment as
required.
(v) Heating, ventilating, and air conditioning (HVAC)
systems.
(I) Code requirements. All central HVAC systems shall
comply with and shall be installed in accordance with the requirements
of NFPA 90A, Standard for the Installation of Air Conditioning and
Ventilating Systems, 1999 edition, or NFPA 90B, Standard for the Installation
of Warm Air Heating and Air-Conditioning Systems, 1999 edition, as
applicable and the requirements contained in this clause. Air handling
units serving two or more rooms are considered to be central units.
(-a-) Temperature and humidity. The indoor design temperature
shall be 75 degrees Fahrenheit with relative humidity of not less
than 30 percent.
(-b-) Thermostat gauges. Thermostats shall be provided
for all heating and cooling systems with an on and off switch.
(-c-) Air handling duct requirements. Fully ducted
supply, return and exhaust air systems shall be provided for all resident
care areas. Combination systems, utilizing both ducts and plenums
for movement of air in these areas shall not be permitted.
(-1-) Protection of ducts penetrating fire and smoke
partitions. Combination fire and smoke leakage limiting dampers (Class
II) shall be installed in accordance with manufacturer's instructions
for all ducts penetrating 1 and 2-hour rated fire and smoke partitions
required by NFPA 101, §12-6.3.7, Subdivision of Building Space,
(not required in SCFs meeting the provisions of NFPA 101, §12-6.3.7.3,
Exception).
(-2-) Fail-safe installation. Combination smoke and
fire dampers shall close on activation of the fire alarm system by
smoke detectors installed and located as required by NFPA 72, Chapter
5, National Fire Alarm Code, 1996 edition; NFPA 90A, Chapter 4; and
NFPA 101, §12-6.3.7; by activation of the fire sprinkler system;
and upon loss of electrical power. Smoke dampers shall not close by
fan shut-down alone. This requirement applies to all existing and
new installations.
(-3-) Interconnection of air handling fans and smoke
dampers. Air handling fans and smoke damper controls shall be interlocked
so that closing of smoke dampers will not damage the ducts.
(-4-) Frangible devices. The use of frangible (non-resetting)
devices for shutting smoke dampers shall not be permitted.
(-d-) Outside air intake locations. Outside air intakes
shall be located at least 10 feet from exhaust outlets of ventilating
systems, combustion equipment stacks, plumbing vents, or areas which
may collect vehicular exhaust or other noxious fumes. (Prevailing
winds and proximity to other structures may require other arrangements).
(-e-) Pressure relationship. Ventilation systems for
a LCF shall be designed and balanced to provide pressure relationships
contained in Table 1 of this title. For reductions and shut down of
ventilation systems when a room is unoccupied, the provisions in Note
4 of Table 1 of this title shall be followed.
(-f-) Duct linings. Friable internal linings shall
not be used in ducts, air terminal units, or other air system components.
This requirement shall not apply to air terminal units and sound attenuators
that have approved nonfriable coverings, e.g., foil facing, over such
linings.
(II) Thermal and acoustical insulation for air handling
systems. Asbestos containing insulation materials shall not be used.
(-a-) Thermal duct insulation. Air ducts and casings
with outside surface temperature below the ambient dew point or temperature
above 80 degrees Fahrenheit shall be provided with thermal insulation.
(-b-) Insulation in air plenums and ducts. When installed,
linings in air ducts and equipment shall meet the Erosion Test Method
described in Underwriters' Laboratories, Inc., Standard 181, Factory-Made
Duct Materials and Air Duct Connectors. This document may be obtained
from the Underwriters' Laboratories, Inc., 333 Pfingsten Road, Northbrook,
IL 60062-2096.
(-c-) Insulation flame spread and smoke developed ratings.
Interior and exterior insulation, including finishes and adhesives
on the exterior surfaces of ducts and equipment, shall have a flame
spread rating of 25 or less and a smoke developed rating of 50 or
less as required by NFPA 90A, Chapters 2 and 3 and as determined by
an independent testing laboratory in accordance with NFPA 255, A Standard
Method of Test of Surface Burning Characteristics of Building Materials,
1999 edition.
(-d-) Friable insulation. Insulation of soft and spray-on
types shall not be used where it is subject to air currents or mechanical
erosion or where loose particles may create a maintenance problem
or occupant discomfort.
(vi) Piping systems and plumbing fixture requirements.
All piping systems and plumbing fixtures shall be designed and installed
in accordance with the requirements of the International Plumbing
Code (IPC), 2000 edition. The IPC is published by the International
Code Council, 5203 Leesburg Pike, Suite 600, Falls Church, VA 22041,
