Safety Design Guidance:
a.
In-duct systems should be fully enclosed to prevent leakage of UV radiation to
unprotected persons or materials outside of the HVAC equipment.
b.
All access panels or doors to the lamp chamber and panels or doors to
adjacent chambers where UV radiation may penetrate or be reflected should
have warning labels in appropriate languages. Labels should be on the outside
of each panel or door, in a prominent location visible to people accessing the
system.
c.
Lamp chambers should have electrical disconnect devices. Positive
disconnection devices are preferred over switches. Disconnection devices
must be able to be locked or tagged out, and should be located outside the
lamp chamber, next to the chamber’s primary access panel or door. Switches
should be wired in series so that opening any access door deenergizes the
system. On/off switches for UV lamps must not be located in the same
location as general room lighting; instead, they must be in a location that only
authorized persons can access, and should be locked to ensure that they are
not accidentally turned on or off.
d.
The lamp chamber should have one or more viewports of UVC-absorbing
materials. Viewports should be sized and located to allow an operating UV
system to be viewed from outside of the HVAC equipment.
e.
Air Handling Units containing UV lighting systems systems should have on/off
switches and an electrical disconnect device on the louvers. If UV radiation
measurements at the time of initial installation exceed the recommended
exposure limit, all highly UV-reflecting materials should be removed, replaced,
or covered. UV-absorbing paints containing titanium oxide can be used on
ceilings and walls to minimize reflectance in the occupied space.

information:

Caution: Ultraviolet energy in duct. Do not switch off safety button or activate
lamps with door open.
10.
Personnel Safety Training
a.
Workers should be provided with as much training as necessary, including
health and safety training, and some degree of training in handling lamps and
materials. Workers should be made aware of hazards in the work area and
trained in precautions to protect themselves. Training topics include
(1)
UV exposure hazards
(2)
Electrical safety
(3)
Lock-out/tag-out
(4)
Health hazards of mercury
(5)
Rotating machinery
(6)
Slippery condensate pans
(7)

(9)

b.
Workers expected to clean up broken lamps should be trained in proper
protection, cleanup, and disposal.
c.
No personnel should be subject to direct UV exposure, but if exposure is
unavoidable, personnel should wear protective clothing (no exposed skin),
protective eyewear, and gloves. Most eyewear, including prescription glasses,
area sufficient to protect eyes from UV, but not all offer complete coverage;
standard-issue protective goggles may be the best alternative.

Section 237300
d.
If individual lamp operating condition must be observed, this should
preferably be done using the viewing window(s).
e.
Access to lamps should only be allowed when lamps are de-energized. The
lamps should be turned off before air-handling unit (AHU) or fan shutdown to
allow the lamps to cool and to purge any ozone in the lamp chamber (if
ozone-producing lamps are used). If AHUs or fans are de-energized first, the
lamp chamber should be opened and allowed to ventilate for several minutes.
Workers should always wear protective eyewear and puncture-resistant
gloves for protection in case a lamp breaks.
f.
Access to the lamp chamber should follow a site-specific lock-out/tag-out
procedure. Do not rely on panel and door safety switches as the sole method
to ensure lamp de-energizing. Doors may be inadvertently closed or switches
may be inadvertently contacted, resulted in unexpected lamp activation.
g.
If workers will enter the condensate are of equipment, the condensate pan
should be drained and any residual water removed.
h.
In general, avoid performance readings with the fan running and workers
inside an AHU (e.g., to test for output reduction caused by air cooling). Tests
of this nature should be instrumented and monitored from outside the
equipment.
During maintenance, renovation, or repair work in areas where UV systems are
present, all UVGI systems must be deactivated before personnel enter the area.
P. Shipping splits will be provided as necessary to fit the units into place. Lifting lugs will be
provided where required for proper lifting. Shipping splits shall be coordinated with
mechanical contractor prior to units being released for construction.

E. Where equivalent manufacturers for lighting fixtures are not indicated or scheduled, one
manufacturer and model number is listed as “Design Standard” on the fixture schedule. The
intent is to define the appearance, style, function, performance, and level of quality deemed
necessary by the architect as well as to define the standard used by the architect as the basis
of the design described by the drawings and specifications. Light fixtures equal in the
appearance, style, function, performance, and level of quality as manufactured by other than
the “Design Standard” manufacturer may be proposed by the Contractor at or before
submittal. The proposed material will be evaluated by the Design Professional and
determination of equality with the “Design Standard” will not be unreasonably withheld. To
assist in this determination, the Contractor shall submit detailed photometric and power
density calculations for each space that the proposed alternate fixture will be utilized. If the
alternate manufacturer or model is determined by the Design Professional to not be equal to
the “Design Standard” in a parameter whose acceptance would not be in the best interest of
the Owner, the alternate fixture will be rejected. The Contractor may then submit, at no
additional cost to the owner, another alternate fixture or the fixture scheduled as the “Design
Standard” for review by the Design Professional. Alternate material furnished shall comply
with all requirements of the material specification, shall be, as determined by the Design
Professional, equal in form and performance to the “Design Standard” and shall be
dimensionally identical to the design standard where features are visible or where the work of
other trades is affected. Determination of equally shall remain solely with the architect and
his decision shall be final.
