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 Vantage unit for a 30-minute cycle is less than
two seconds. For more information, view the recommended standards from NIOSH (

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. For

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.
