Occupational Safety and Health Administration (OSHA)
The Occupational Safety and Health Administration (OSHA) does not have any mandated
exposure limits to ultraviolet light. OSHA only provides technical guidance regarding
protecting employees from ultraviolet laser exposure. While general information about
ultraviolet contained in that guidance is described below, it is important to note that Violet
Defense Technology does not currently deploy ultraviolet lasers. For more information on
OSHA’s guidelines, visit

.
Ultraviolet radiation is divided into three regions: UV-A: 315-400 nanometers (nm), UV-B:
280-315 nm, and UV-C: 100-280 nm. UV can be associated with adverse health effects due
to prolonged exposure and the wavelength of light.
According to OSHA’s guidelines, “exposure in the shorter UV-C and longer UV-A ranges
seems less harmful to human skin. The shorter wavelengths are absorbed in the outer dead
layers of the epidermis and the longer wavelengths have an initial pigment-darkening effect
followed by erythema if there is exposure to excessive levels.”
“The hazards associated with skin exposure are of less importance than eye hazards.”
Exposure to light may cause photokeratitis or cataracts.
National Institute for Occupational Safety and Health (NIOSH)
The National Institute for Occupational Safety and Health (NIOSH) recommends limits to
exposure determined by the wavelength of UV light and intensity. NIOSH recommends that
the time of exposure to an intensity of 100 microwatts per square centimeter at wavelength
254 nm not exceed 1 minute. Per the programming, UV exposure from this unit for a
30-minute cycle is less than two seconds. For more information, view the recommended
standards from NIOSH (
https://www.cdc.gov/niosh/docs/73-11009/pdf/73-11009A.pdf
).
Environmental Protection Agency (EPA)
The Environmental Protection Agency (EPA) is the governmental agency responsible for
regulating ultraviolet light products. It regulates chemical disinfectants along with devices,
such as equipment that generates UV light, used to control pests like bacteria and making
antimicrobial claims. Violet Defense is an EPA-registered company (Facility No. 92142) and
is in full compliance with all regulations. For more information about EPA guidelines, visit

.
Food and Drug Administration (FDA)
The Food and Drug Administration (FDA) only regulates devices that are classified as medical
instruments, machines, and devices used to treat diagnosed medical conditions. Therefore,
Violet Defense does not fall under FDA guidelines.
