Section 2: NuvaWave Safety Information
2.1 UVC RADIATION AND HOW IT WORKS
The visible spectrum of light has been well characterized and can easily be seen in the colors of a
rainbow from purple (400 nm) to red (700 nm). As the wavelength increases, the energy of the photon
decreases, as seen in Figure 2.1a.
Figure 2.1a The electromagnetic spectrum
Ultraviolet (UV) radiation was discovered in 1801 by Johann Wilhelm Ritter, a German physicist, as he
observed that invisible rays beyond the violet end of the visible spectrum darkened silver chloride-
based paper. Over the next 100 years, scientists began to learn the power of the ultraviolet spectrum,
(Figure 2.1b) and in 1878 they discovered the disinfecting effect of short wavelength UV light on
bacteria.
NuvaWave Handheld Disinfection Device Instructions for Use
037-0110 (Rev C) © 2020 UV Innovators, LLC Page 15 of 35
Figure 2.1b Ultraviolet wavelength subdivided spectral ranges
.
The UV spectrum is subdivided into 4 different ranges and they each have different features or uses:
•UVA: (315 –400 nm, long wavelength) is used in tanning beds, curing applications, and black
lights for forensics.
•UVB: (280 –315 nm, medium wavelength) is used in phototherapy/psoriasis applications; this
is the wavelength that causes sun burn and skin cancers.
•UVC: (200 –280 nm, short wavelength) is very effective for pathogen disinfection of
surfaces, water, or air.
•VUV: (100 –200 nm, vacuum UV) is used to produce ozone plasmas.
2.2 EFFECTS OF UVC RADIATION ON HUMANS
The sun generates light that covers the entire electromagnetic spectrum. The Earth’s atmosphere is
blocking a significant portion of that spectrum from reaching the surface. UVC is blocked by our upper
atmosphere and only UVB, UVA are visible, and infrared light are able to penetrate and interact with
humans. The protective layer of the atmosphere saves humans from detrimental exposure to UVC
energy. Human cells interact with photonic energy in many different ways. For instance, near-UVA
and visible light is absorbed by chromophores in cells and the transfer of energy stimulates
independent cellular mechanisms. Most of those mechanisms are beneficial to the human body, since
secondary effects of the photon absorption cause chain reactions in the cells that are protective and
healthy.

As an example, the absorption of UVB into the skin is responsible for the formation of vitamin

Glickman, Gena, et al., Light therapy for seasonal affective disorder with blue narrow-band light emitting diodes, Biological
Psychiatry; 59, 502-507, 2006.
NuvaWave Handheld Disinfection Device Instructions for Use
037-0110 (Rev C) © 2020 UV Innovators, LLC Page 16 of 35
D in humans. In another mechanism of action, cellular activation by photonic interaction can cause
these cells to produce reactive oxygen species that can attack bacteria and destroy their membranes.
2
UVC acts in a direct mechanism with the DNA of mammalian cells. The UVC energy is absorbed by the
cells and causes a disruption of the thymine dimers of the DNA sequence and the RNA of viruses. This
disruption renders the cells to be unable to replicate or reproduce.
3
This effectively restricts and
causes the cells to die making the UVC wavelength very efficient at pathogen reduction. For this
reason, UVC is known as the germicidal irradiation wavelength.
2.3 HOW TO PROTECT YOURSELF FROM DETRIMENTAL UVC RADIATION EXPOSURE
Since the UVC wavelength of light can disrupt the DNA of cells, it is a requirement to protect humans
from this powerful wavelength. The lens of the human eye absorbs most of UVA light, which can cause
cataracts; the shorter wavelengths (UVB & UVC) are absorbed by the cornea, causing potential
damage to these tissues.
4
This is why UV protective eyewear should always be used around UV light. In
addition, the user should wear a NuvaWave face shield (or equivalent UVC certified face shield) to
protect both the eyes and the other exposed skin of the face during the use of products with UVC
irradiation. Most optically transparent polymer materials, like polycarbonate, will block shorter
wavelengths (UVC) and allow visible light to move through. In addition, users of UVC irradiation
devices should protect any exposed skin from direct or indirect exposure to these harmful wavelengths.
Personal Protective Equipment (PPE) is required during disinfection of infected areas. Examples of
PPE are:
Gloves Gown Sleeve covers
Goggles/Glasses Hood Respirator
Face shield Boot covers Face Mask
The minimum required for PPE during the use of NuvaWave is a NuvaWave face shield, gloves, tight
weave long sleeve shirt, tight weave pants, and closed-toe shoes.
2.4 PPE INCLUDED IN THE KIT
The Kit provides 2 PPE face shields. Users should always follow the procedures of the facility where
they are working to ensure all PPE options are utilized properly. In addition to the provided NuvaWave
face shield, the user must cover any exposed skin with clothing such as tight weave long sleeve shirt
and pants, gloves, and closed-toe shoes.
