(i) Sink and lavatory controls. All fixtures used by
medical and nursing staff and all lavatories used by patients and
food handlers shall be trimmed with valves which can be operated without
the use of hands. Blade handles used for this purpose shall not be
less than four inches in length. Single lever or wrist blade devices
may be used.
(ii) Clinical sink traps. Clinical sinks shall have
an integral trap in which the upper portion of a visible trap seal
provides a water surface.
(iii) Back flow or siphoning. All plumbing fixtures
and equipment shall be designed and installed to prevent the back-flow
or back-siphonage of any material into the water supply. The over-the-rim
type water inlet shall be used wherever possible. Vacuum-breaking
devices shall be properly installed when an over-the-rim type water
inlet cannot be utilized.
(iv) Drinking fountain. Each drinking fountain shall
be designed so that the water issues at an angle from the vertical,
the end of the water orifice is above the rim of the bowl, and a guard
is located over the orifice to protect it from lip contamination.
(v) Sterilizing equipment. All sterilizing equipment
shall be designed and installed to prevent not only the contamination
of the water supply but also the entrance of contaminating materials
into the sterilizing units.
(vi) Hose attachment. No hose shall be affixed to any
faucet if the end of the hose can become submerged in contaminated
liquid unless the faucet is equipped with an approved, properly installed
vacuum-breaker.
(vii) Bedpan washers and sterilizers. Bedpan washers
and sterilizers shall be designed and installed so that both hot and
cold water inlets shall be protected against back-siphonage at maximum
water level.
(viii) Flood level rim clearance. The water supply
spout for lavatories and sinks required in patient care areas shall
be mounted so that its discharge point is a minimum of five inches
above the rim of the fixture.
(ix) Floor drains or floor sinks. Where floor drains
or floor sinks are installed, they shall be of a type that can be
easily cleaned by removal of the cover. Removable stainless steel
mesh shall be provided in addition to grilled drain cover to prevent
entry of large particles of waste which might cause stoppages.
(x) Under counter piping. Under counter piping and
above floor drains shall be arranged (raised) so as not to interfere
with cleaning of floor below the equipment.
(xi) Ice machines. All ice making machines shall be
of the self-dispensing type, unless otherwise specified.
(5) General electrical requirements. This paragraph
contains common electrical requirements. The facility shall comply
with the requirements of this paragraph and with any specific electrical
requirements for the particular unit or suite of the facility in
accordance with §134.123 of this title. Electrical systems shall
comply with NFPA 99, Chapter 3.
(A) Electrical installations. All new electrical material
and equipment, including conductors, controls, and signaling devices,
shall be installed in compliance with applicable sections of the National
Fire Protection Association 70, National Electrical Code, 1999 edition

system. Electrical systems and components shall be listed by nationally
recognized listing agencies as complying with available standards
and shall be installed in accordance with the listings and manufacturers'
instructions.
(i) All fixtures, switches, sockets, and other pieces
of apparatus shall be maintained in a safe and working condition.

be properly grounded in accordance with NFPA 70.
(v) Under-counter receptacles and conduits shall be
arranged (raised) to not interfere with cleaning of floor below the
equipment.
(B) Installation testing and certification.
(i) Installation testing. The electrical installations,

is appropriate and functional.
(I) Grounding continuity shall be tested as described
in NFPA 99 for new or existing work.
(II) A written record of performance tests on special
electrical systems and equipment shall show compliance with applicable
