Innovative Bioanalysis LLC. WAC LIGHTING UVF7IN-120V-R1-MOD AEROSOL Page 3 of 11
WAC LIGHTING EQUIPMENT:
The equipment arrived at the laboratory pre-packaged from the manufacturer and was
inspected for damage upon arrival. The equipment needed no installation by lab staff and all LED
diodes came installed and functioning. The UV-C ring and fan housing were operated to confirm
irradiance output and the system was functioning as intended.
VIRAL SAFETY TESTING CHAMBER:
The testing chamber was a large, sealed air volume testing chamber consisting of metal walls
and epoxy floor which complied with BSL3 standards. The chamber was designed to be completely
sealed from the outside environment to prevent any potential release of testing media into the
atmosphere. The testing chamber was equipped with 2 sealed viewing windows and a lockable
chamber door for entry and exit. The overall dimensions of the test chamber were approximately
8’x8’x10’.
For this test no outside air was brought in during testing and intake remained sealed. Humidity
and temperature were monitored inside the chamber using a calibrated wireless device. For air sample
testing, the chamber was equipped with 2 probes that were along the centerline of the room and
protruded down from the ceiling 24”. Each probe tube was connected to a Gilian 10i programmable
system with sampling cassettes from lot #2316 made by Zefron International. A single bioaerosol
nebulizing port was in the center of the 10’ wall. The dissemination port protruded from the wall 24”
and was connected to a programmable compressor nebulizer system.
The UV-C fan combination provided by WAC Lighting was affixed to a mobile stainless-steel
tubular stand inside the test chamber. A 10” down rod was provided by WAC Lighting and was affixed to
the fan body. The main fan motor was approximately 12 inches below the ceiling line of the testing
chamber. The fan operated in the standard forward rotation on a speed setting of 6.
Four pedestal stands were placed near each corner of the room with a height of 12 inches. On
top of each table a single low volume mixing fan was placed to assist homogeneous mixing of the
nebulized virus. Mixing fans had an approximately CFM of 32 and were angled up at approximately 45
degrees. Mixing fan speed were confirmed prior to testing with a vane anemometer.
Prior to testing, the chamber was pressure tested for leaks and visual inspections were made
using a colored smoking device. All seals for the chamber were confirmed and all equipment used had
a function test to confirm working conditions. For calibrated equipment, calibration records were
checked to confirm operational status.
