Time to Disinfect
Uvc light disinfection in fast-paced working environments
Cleaning and disinfecting standards have changed. While it used to be okay to handle everything at the end of the night, you’re now expected to disinfect your facility regularly throughout the day to prevent the spread of infectious disease among your staff and customers. This is fine for a lot of establishments, but some fast-paced environments simply don’t have the resources to keep up with the level of germ killing people want to see.
How dirty are your surfaces?
There are a ton of high-touch surfaces in a fast-paced work environment. Hands are hitting keyboards, switches, countertops, coffeepots, tables, chairs, doors, and more every few minutes. Every time a hand touches a surface, there’s a transfer of pathogens. If the surface presents the right conditions, the viruses, bacteria, and other germs will start to multiply, increasing their chances of infecting every hand to touch that surface after. In just 24 hours, some pathogens can multiply from a single germ to almost 7 septillion germs.
What is UVC light?
UVC light is a frequency range (100-280 nanometers) of ultraviolet light that can penetrate the surfaces of viruses, bacteria, and other pathogens to deactivate or kill them by disrupting their DNA. Neutralizing different pathogens requires specific minimum fluences.
The total measure of irradiance over the time the light is applied.
The value of milliwatts per square centimeter arriving at the surface.
If a lamp has an irradiance value of 5mw/cm2 and is applied for 20 seconds, the fluence will be 100mj/cm2 (1 milliwatt = 1 millijoule). The virus that causes COVID-19 requires 5mj/cm2 for 99% deactivation. That means a lamp with an irradiance value of 5mw/cm2 would only need to be applied for one second to deactivate 99% of SARS-CoV-2.
UVC Light vs Manual Cleaning Methods
According to a study conducted in a hospital to compare the efficacy of standard operating procedure versus UVC light disinfection, UVC light was able to increase the number of negative samples (samples that were free of pathogens) by 45%. The SOP included chlorine-based detergent, Antisapril detergent 10%, Angelini, chlorine-based disinfectant, Antisapril disinfectant 10%, and Angelini (2800mg/L active chlorine) and was carried out by a professional cleaning service. The UVC protocol involved bedside UVC exposure for two 5-minute cycles and 10-minute cycles in operating rooms.
The Best UVC Light for Disinfecting Work Surfaces
The VDC Health’s SLCR Zapper effectively disinfects work surfaces in just seconds. It’s a handheld lamp that allows you to quickly and thoroughly eliminate dangerous pathogens, including SARS-CoV-2, without any harsh chemicals, ventilation, or repetitive cleaning and rinsing.
It’s important to be cautious when purchasing UVC lights for disinfecting because there are a large number of fraudulent dealers selling regular UV lights. UV lighting that isn’t within the C range is not effective against pathogens. VDC Heath is a member of the IUVA and a reputable UVC vendor with a range of UVC lamps for whole-room disinfection, handheld surface disinfection, home disinfection, and more.
