Deposition of respiratory droplets and particles on exposed mucous membranes in the mouth, nose, or eye by direct splashes and sprays.ģ. Inhalation of very fine respiratory droplets and aerosol particles.Ģ. Exposure occurs in three principal ways:ġ. The principal mode by which people are infected with SARS-CoV-2 (the virus that causes COVID-19) is through exposure to respiratory fluids carrying infectious virus.While minimizing associated energy penalties.

Nadia Storm et al, Rapid and complete inactivation of SARS-CoV-2 by ultraviolet-C irradiation, 2020.With earlier contributions by Gabriel Chevrefils (2006) and Eric Caron (2006) With peer review by Benoit Barbeau, Harold Wright (1999) and Karl G. Fluence (UV Dose) Required to Achieve Incremental Log Inactivation of Bacteria, Protozoa, Viruses and Algae Revised, updated and expanded by Adel Haji Malayeri, Madjid Mohseni, Bill Cairns and James R.EPA Report, “Building Retrofits for Increased Protection Against Airborne Chemical and Biological Releases” Pg.They should never be used in applications or activities that may cause and/or lead to death, personal injury and/or damage to the environment. Plants and/or materials that are exposed to higher dosages of UV-C may become damaged and/or discolored. None of our UV-C lamps are certified or approved as a medical device anywhere in the world and should not be used as such. Philips UV-C disinfection luminaires must only be sold by Signify or through qualified partners and installed by qualified professionals according to our stringent safety and legal requirements. The UV-C disinfection luminaires we provide without such safeguards are intended only to be used as components in disinfection systems that contain any safeguards indicated, but not limited to, those specified in mounting instructions and user manuals. The lighting must always be installed with adequate shields and safeguards (such as presence detection sensors or timers) to avoid light damage and severe injuries to the eyes and skin. UV-C lighting presents minimum risk when used in the correct way.
