After more than 14 months of pandemic, we have been adjusting ourselves to a better hygiene level. From wearing masks, keeping our distance, staying home, and washing our hands.
Aside from that, scientists and engineers have tried to develop several new ways to disinfect, or get rid of bacterias and viruses on various surfaces to help the spread of the virus. One of the ways to do it is by using Ultraviolet lights, specifically UV-C.
Hospitals have been using UV-C lights for a while to disinfect surfaces, long before the pandemic. But what is exactly UV-C light and UV light itself?
UV or ultraviolet light is electromagnetic radiation with wavelengths shorter than visible lights, but longer than X rays. Which means, we can’t see UV lights because it's outside of our eye’s capability to see. There are several types of ultraviolet, UV-A, UV-B, and UV-C. UV-C radiation has a strong germicidal and embryocidal effect. It also can cause burning of the skin and inflammation of eyes.
A safe utilization of UV-C is important because the exposure to it is harmful to any living being and could also potentially cause cancer. Other than that, prolonged exposure of UV-C can degrade materials that’s been exposed.
If you think UVC light is a necessity for you to disinfect effectively as a precaution from Covid-19, and you can afford it, here’s some things to know about how it works for common use, and how to use it safely.
There are several devices that you can use at home, there’s UV-C light box, handheld portable UV-C light, and there's also UV-C luminaire.
You can use a UV-C light box as a disinfectant for your clothes and gadgets just after you go out of your house, you can put everything in the box and turn it on for several minutes before washing the clothes or using your gadget again. This way is the easiest and safest way to use UV-C because there’s little risk of exposing yourself to the harmful effects of UV-C. While with the handheld device, its flexibility allows you to shine the light to any kinds of surfaces, but kindly be more careful not to expose yourself or others with it, because exposure to the light can be very harmful to humans, and even pets.
