Can UV Disinfection Lamps Kill Covid-19?

The novel coronavirus, also known as Covid-19, has caused serious public concern regarding how we can prevent the spread of such a contagious illness. From stopping incoming persons aboard aircraft and boats to placing entire populations on “stay at home” orders – it is clear that even the government is willing to take extreme steps to combat Covid-19. But are there more ways we can prevent the spread of this illness that goes beyond face masks and social distancing? For those in medical fields, the use of ultraviolet (UV) disinfection lamps is not a new practice. However, the idea of using lights to kill bacteria and inactivate viruses may be new to almost everyone else. If you have never heard of the use of UV disinfection lamps or know very little, the experts with Action Services Group are here to help. Below, we explain why ultraviolet disinfection lamps may help negate the spread of Covid-19, as well as other illnesses.

Do UV Disinfection Lamps Kill Covid-19?

Before we get into the effectivity of using UV disinfection laps to kill Covid-19, there are a few things we need to discuss. The first is how viruses are classified.

Virus Classifications

When it comes to disinfection resistance, there are 3 levels of classification.

  • Class 1 viruses are small, non-enveloped viruses that measure below 50nanometers (nm). These viruses are considered the hardest to disinfect as they are highly resistant.
  • Class 2 viruses are large, non-enveloped viruses over 50nm. These are less resistant to disinfection, making them less hard to kill.
  • Class 3 viruses are enveloped viruses. These are the easiest to kill and offer the least resistance to disinfection.

What We Know About Covid-19

To date, very little is known about Covid-19. According to the Centers for Disease Control and Prevention (CDC), we believe that Covid-19 is spread primarily through inhaling respiratory droplets from infected individuals. Because this typically occurs when a person sneezes, coughs, or even talks around you, the CDC has recommended individuals wear masks and stay at least 6 feet apart. Additionally, you can become contaminated through touching surfaces where the virus may sit, then touching your mouth, nose, or eyes.

For additional safeguards against Codiv-19 and other contagions, Action Services Group offers a wide range of portable and installed plexiglass sneeze guards for added protection. Visit Shop Sneeze Guards for more product information.  

UV-C Light Disinfection & Covid-19

Covid-19 is a Class 3 virus. However, not all UV disinfection lamps have validated their claims that they can kill Covid-19. UV light is separated into 3 sub-bands based on wavelengths. UV-A wavelengths (315nm – 400nm) and UV-B wavelengths (280nm – 315nm) are commonly used for things like tanning, printing, and other non-essential applications. UV-C lighting (200nm-280nm) however is considered germicidal and the most effective lamp for disinfection.

In order for a UV disinfection lamp to be approved for use by the CDC, it must pass through validation. To do so, the lamp must prove that it can kill a Class 1 virus. (In doing this, it proves that it can kill the most resistant type of bacteria or virus strands and can, therefore, eliminate those of lesser resistance as well.) Because of this, it is important that you confirm with your provider that any UV-C light being used for disinfection has indeed been validated. (At Action Services Group, we monitor all UV-C light disinfection claims and verify validation!)

Can Ultraviolet Disinfection Lamps Be Used on Other Viruses?

UV disinfection lamps can be used on other bacteria and viruses. In fact, UV-C light disinfection has been used to combat illnesses, including norovirus, reoviridae, adenoviridae, tuberculosis, Ebola, and influenza. UV-C light disinfection works because, at these wavelengths, the UV light is able to damage the RNA and DNA of microorganisms and pathogens. When this occurs, it inhibits the spread of the disease because the bacteria or virus can no longer reproduce. In fact, experts agree that UV-C light disinfection is so effective it can kill up to 99.9% of all viruses, pathogens, and bacteria.

UV-C Light Disinfection with Action Services Group

Using UV disinfection lamps is highly recommended in the fight against illnesses and diseases.  Furthermore, the CDC has also pointed out that there have been no reports of microbes being able to build up an immunity to light-based disinfection methods. This is not true of chemical methods, which we know certain illnesses can develop an immunity to.
