Emergency Lighting Regulations

Did you know that you are required by law to
have and test regularly exit & emergency
lighting systems? Do not take a chance with such
serious matters: avoid serious liabilities and
fines by having, maintaining and testing
adequate exit and emergency lighting systems in
your building.
All lighting systems that we
design and install rigorously adhere to the
current lighting regulations and the best
practices in your area. As for testing, rely on
our exclusive, patented methodology of testing
exit signs and emergency lighting systems - it
is more affordable than you think, and it is the
law!
Following are some lighting
regulations on test and maintaining Exit &
Emergency lighting systems:
An annual test shall be conducted for a
1-1/2 hour duration. Equipment shall be fully
functional for the duration of the test.
A functional test shall be conducted on
every required emergency lighting system
at 30-day intervals for a minimum of
30-seconds.
SECTION 5-8 ILLUMINATION
OF MEANS OF EGRESS
5-8.1 General.
5-8.1.1 Illumination of means
of egress shall be provided in accordance with
section 7.8 for every building and structure
where required in Chapters 11 through 42. For
the purposes of this requirement, exit access
shall include only designated stairs, aisles,
corridors, ramps, escalators, and passageways
leading to an exit.
5-8.1.2 Illumination of means
of egress shall be continuous during the time
that the conditions of occupancy require that
the means of egress be available for use.
Artificial Lighting shall be employed at such
places and for such periods of time as required
to maintain the illumination to the minimum
footcandle {Lux(lx)} values herein specified.
5-8.1.3*
The floors of means of egress shall be
illuminated at all points including angles and
intersections of corridors and passageways,
stairways, landings of stairs, and exit doors to
values of not less than 1 footcandle (10 lx)
measured at the floor. Exception: In assembly
occupancies, the illumination of the floors of
exit access shall be not less than 1/5
footcandle (2 lx) during periods of performances
or projections involving directed light.
5-8.1.4 Any required
illumination shall be so arranged that the
failure of any single Lighting unit, such as the
burning out of an electric bulb, will not leave
any area in darkness.
SECTION 5-9 EMERGENCY Lighting
5-9.1 General.
5-9.1.1 Emergency Lighting
facilities for means of egress shall be provided
in accordance with this section for every
building or structure where required in Chapters
8 through 30. For the purposes of this
requirement, exit access shall include only
designated stairs, aisles, corridors, ramps,
escalators, and passageways leading to an exit.
5-9.1.2 Where maintenance of
illumination depends upon changing from one
energy source to another, there shall be no
appreciable interruption of illumination during
the changeover. Where emergency Lighting is
provided by a prime mover-operated electric
generator, a delay of not more than 10 seconds
shall be permitted.
5-9.2 Performance of System.
5-9.2.1* Emergency illumination
shall be provided for a period of 1 1/2 hours in
the event of failure of normal Lighting.
Emergency Lighting facilities shall be arranged
to provide initial illumination that is no less
than an average of 1 footcandle (10 lx) and a
minimum at any point of .1 footcandle (1 lx)
measured along the path of egress at floor
level. Illumination levels may decline to .6
footcandle (6 lx) average and a minimum at any
point of .06 footcandle (.6 lx) at the end of
the emergency Lighting time duration. A maximum
to minimum illumination uniformity ratio of 40
to 1 shall not be exceeded.
5-9.2.2* The emergency Lighting
system shall be so arranged as to provide the
required illumination automatically in the event
of any interruption of normal Lighting, such as
any failure of public utility or other outside
electrical power supply, opening of a circuit
breaker or fuse, or any manual act(s), including
accidental opening of a switch controlling
normal Lighting facilities.
