More Companies Are Turning To Ultraviolet Rays To Fight Viruses


It may sound like something out of a Sci-fi movie but Ultraviolet ray is the latest weapon companies are using to fight harmful microorganisms in the current pandemic situation.

The Covid-19 outbreak has brought a significant impact on many industries all over the world with many businesses such as air travel, hotels, and other tourism-related companies being the worst hit by the pandemic. With many countries practicing stricter controls on cross border travel and safe distancing measures, we are seeing a rise in retail and F&B businesses winding up due to a substantial drop in earnings in light of the bleak economic outlook and continual downward spiral of the economy.

There are many ways businesses can adopt to increase their competitiveness and weather through this storm, for example; they can increase customers’ confidence with the use of Ultraviolet light and steriliser related equipment in their shops to protect both the customer and staff against the spread of Covid-19 within their premises.


UV-A, UV-B, and UV-C

When people think of ultraviolet rays, the first thing that comes to mind is the ultraviolet rays from the sun. We could have sun damage to our skin for as little as 15 minutes of fun under the sun, as such it is common to see many advertisements promoting the use of sunscreen to prevent skin cancer, premature aging and other harmful effects from the sun.

All UV radiation has the potential to damage your skin, but each type affects our skin differently.


How Does Ultraviolet (UV-C) Sterilisation Work?

Ultraviolet technology has been in use for more than 50 years and its effectiveness has been widely documented scientifically.

Ultraviolet (UV-C) changes the micro-organisms (germs, bacteria, and viruses) DNA structure, making it incapable of reproducing​. If a cell cannot reproduce, it is considered dead or “inactivated”.

Ultraviolet rays can kill viruses and many microscopic organisms. Studies have shown that ultraviolet sterilisation can kill Hand, Foot & Mouth viruses (Coxsackie A) at a minimum dosage of 6.9 mJ/cm2 and other common bacteria like E. Coli that causes food poisoning at a minimum dosage of 8.6 mJ/cm2.

UV sterilisation tests done on 2 common bacteria which cause food poisoning have shown that 99.99% of bacteria were eliminated after going through 30 mins of UV-C sterilisation process.
