Can UVC Light Kill Virus?

Can UVC Light Kill Virus?

.
.
Since the finding in 1878, artificially produced UVC has become a staple method of sterilization – one used in hospitals, aeroplanes, offices, and factories every day. Crucially, it’s also fundamental to the process of sanitizing drinking water; some parasites are resistant to chemical disinfectants such as chlorine, so it provides a failsafe.
.
.
UVC radiation is a known disinfectant for air, water, and nonporous surfaces. UVC radiation has effectively been used for decades to reduce the spread of bacteria, such as tuberculosis. For this reason, UVC lamps are often called “germicidal” lamps.
.
.
UVC radiation has been shown to destroy the outer protein coating of the SARS-Coronavirus, which is a different virus from the current SARS-CoV-2 virus. The destruction ultimately leads to inactivation of the virus. The radiation warps the structure of their genetic material and prevents viral particles from making more copies of themselves.
.
.
Nevertheless, a concentrated form of UVC is now on the front line in the fight against Covid-19. In China, whole buses are being lit up by the ghostly blue light each night, while squat, UVC-emitting robots have been cleaning floors in hospitals. Banks have even been using the light to disinfect their money.

.
.
To use UVC safely, you need specialist equipment and training. The World Health Organization (WHO) has issued a stern warning against people using UV light to sterilize their hands or any other part of their skin.

Is it safe to use a UVC lamp for disinfection purposes at home?

.
.
Consider both the risks of UVC lamps to people and objects and the risk of incomplete inactivation of the virus.
.
.
Risks: UVC lamps used for disinfection purposes may pose potential health and safety risks depending on the UVC wavelength, dose, and duration of radiation exposure. The risk may increase if the unit is not installed properly or used by untrained individuals.
.
.
  • Direct exposure of skin and eyes to UVC radiation from some UVC lamps may cause painful eye injury and burn-like skin reactions. Never look directly at a UVC lamp source, even briefly.
.
.
  • Some UVC lamps generate ozone. Ozone inhalation can be irritating to the airway.
.
.
  • UVC can degrade certain materials, such as plastic, polymers, and dyed textile.
.
.
  • Some UVC lamps contain mercury. Because mercury is toxic even in small amounts, extreme caution is needed in cleaning a lamp that has broken and in disposing of the lamp.
.
.
Due to that, e LED provides you with a better & safer UVC disinfectant light that is safe for human & animal.  The main features are our UVC light were equipped with a motion sensor & timer so that it won’t effect the operator or people around it.
.
.
The motion sensor will detect any movement in the 2-meter radius and will automatically switch off immediately. Once there is no movement detected, the system will turn on back and continue to operate.
