during emergency. Radio transceivers where installed for emergency
use must be capable of operating for at least one hour upon total
failure of both normal and emergency power.
(ii) The following systems must be arranged for delayed
automatic or manual connection to the alternate power source:
(I) Heating equipment must provide heating for general
resident rooms. This will not be required if:
(-a-) the outside design temperature is higher than
20 degrees Fahrenheit (-6.7 degrees Celsius);
(-b-) the outside design temperature is lower than
20 degrees Fahrenheit (-6.7 degrees Celsius) and, when selected rooms
are provided for the needs of all confined residents, then only those
rooms need to be heated; or
(-c-) the facility is served by a dual source of normal
(II) In instances when interruptions of power would
result in elevators stopping between floors, throw-over facilities
must be provided to allow the temporary operation of any elevator
for the release of passengers.
(C) The emergency lighting must be automatically in
operation within ten seconds after the interruption of normal electric
power supply. Emergency egress lighting must not be switched.
(D) Emergency service to receptacles and equipment
may be delayed automatic or manually connected. Receptacles connected
to emergency power must have red faceplates.
(E) The design and installation of emergency motor
generators must be in accordance with NFPA 37, NFPA 99, and NFPA 110.
(i) Generators must be located a minimum of three feet
from a combustible exterior building finish and a minimum of five
feet from a building opening, if located on the exterior of the building.
(ii) Generators located on the exterior of the building
must be provided with a noncombustible protective cover or be protected
as per manufacturer's recommendations.
(iii) Motor generators fueled by public utility natural
gas must have the capability to be switched to an alternate fuel source
in accordance with NFPA 70.
(iv) Stored fuel capacity must be sufficient for not
less than four hours of required generator operation.
(F) The normal wiring circuits for the emergency system
must be kept entirely independent of all other wiring and must not
enter the same race-ways, boxes, or cabinets according to NFPA 70.
(2) General Lighting Requirements. General lighting
requirements are as follows:
(A) All spaces occupied by people, machinery, equipment,
approaches to buildings, and parking lots must have lighting.
(B) All quality, intensity, and type of lighting must
be adequate and appropriate to the space and all functions within
(C) Minimum lighting levels can be found in the Illuminating
Engineering Society (IES) Lighting Handbook, latest edition. Minimum
illumination must be 20-foot candles in resident rooms, corridors,
nurses' stations, dining rooms, lobbies, toilets, bathing facilities,
laundries, stairways, and elevators. Illumination requirements for
these areas apply to lighting throughout the space and are measured
at approximately 30 inches above the floor anywhere in the room. Minimum
illumination for over-bed reading lamps, medication-preparation or
storage areas, kitchens, and nurses' station desks must be 50 foot
candles. Illumination requirements for these areas apply to the task
performed and are measured on the task.
(D) Nursing unit corridors must have general illumination
with provisions for reduction of light levels at night.
(E) Exposed incandescent light bulbs or other high
heat generating lamps in closets or other similar spaces must be provided
with basket wire guards or other suitable shield to prevent contact
of combustible materials with the hot bulb and to help prevent breakage.
(F) Exposed incandescent or fluorescent bulbs are not
permitted in food service or other areas where glass fragments from
breakage may get into food, medications, linens, or utensils. All
fluorescent bulbs will be protected with a shield or catcher to prevent
(3) Receptacles or convenience outlets.
(A) Receptacles at bedrooms must be according to §19.334(a)(7)

of ends of corridors. At least one duplex receptacle in each resident
corridor must be provided with emergency electrical service.
(C) Receptacles must be provided for essential needs
such as medication refrigerators and systems or equipment whose failure
is likely to cause major injury or death to a resident. All receptacles
on emergency circuits must be clearly, distinctly, and permanently
identified, such as using a red faceplate or a small label that says
(D) Receptacles in the remainder of the building must
be sufficient to serve the present and future needs of the residents
(E) Location of receptacles, horizontally and vertically,
should be carefully planned and coordinated with the expected designed
use of furnishings and equipment to maximize their accessibility and
to minimize conditions such as beds or furniture being jammed against
plugs used in the outlets.
(F) Exterior receptacles must be an approved waterproof
(G) Ground fault interruption protection must be provided
at appropriate locations such as at whirlpools and other wet areas
according to the NFPA 70.
(4) Nurse call systems.
(A) A nurse call system consists of power units, annunciator
control units, corridor dome stations, emergency call stations, bedside
call stations, and activating devices. The units must be compatible
and listed by a nationally recognized testing laboratory for the system
and use intended.
(B) Each resident bedroom must be served by at least
one call station and each bed must be provided with a call switch.
Two call switches serving adjacent beds may be served by one calling
station. Each call entered into the system must activate a corridor
dome light above the bedroom, bathroom, or toilet corridor door, a
visual signal at the nurses' station which indicates the room from
which the call was placed, and a continuous or intermittent continuous
audible signal of sufficient amplitude to be clearly heard by nursing
staff. The amplitude or pitch of the audible signal must not be such
that it is irritating to residents or visitors. The system must be
designed so that calls entered into the system may be canceled only
at the call station. Intercom-type systems which meet this requirement
(C) A nurse call system that provides two-way voice
communication must be equipped with an indicating light at each call
station which lights and remains lighted as long as the voice circuit
(D) A nurse call emergency switch must be provided
for resident use at each resident's toilet, bath, and shower. These
switches must be usable by residents using the fixtures and by a collapsed
resident lying on the floor.
