With restrictions being lifted across Australia, the threat of another COVID-19 outbreak is an ongoing concern. However, many businesses continue to neglect a critical transmission method. A recent study by the Washington Post used a military-grade camera to show just how easily COVID-19 can spread in the air – and the results were “very, very telling”.
In October, the US Centres for Disease Control and Prevention said COVID-19 can spread via exposure to tiny droplets and particles exhaled by an infected person, and droplets and particles can linger in the air for minutes to hours.
To visually illustrate the risk of airborne transmission in real-time, The Washington Post used a military-grade infrared camera capable of detecting exhaled breath. The full article on this study is available on The Sydney Morning Herald.
The results were “very, very telling” according to Rajat Mittal, a professor of mechanical engineering in Johns Hopkins University’s medical and engineering schools and an expert on virus transmission. In fact, experts, believe the footage actually under-represents the potential risk of exposure from airborne particles, which may spread farther or linger longer than the visible exhalation plume and dissipates quickly to a level of concentration the camera can no longer detect.
As part of their study, they recorded a video to highlight how far exhaling can spread and linger in the air. Laughing, yelling or singing are, of course, significant transmission methods as well.
Why you need to address airborne transmission in your business
Every business has it’s high-risk areas. This may be an area with low ventilation, or where people may sit/stand and congregate for periods of time (such as a customers line up for food/drinks, waiting rooms, lobby areas, high customer flow zones). Keeping businesses open and free from restrictions is priority number one.
It’s great to see restrictions lifting, but we all must take every possible step to prevent another lockdown. While COVID-safe plans address direct contact and surface treatment regulations, airborne transmission is largely unaddressed. Implementing an airborne treatment plan is vital to keeping businesses and industries open.
OHAir reduces the risk of airborne transmission
Using human-safe hydroxyl generation technology, OHAIr is able to quickly intercept viral aerosol clouds and eliminate pathogens – without the use of chemicals and being completely-human safe – OHAir is the only solution that fits this airborne treatment role in an operational environment. Using FDA approved technology, the system can operate 24 hours a day, providing continuous treatment in any occupied indoor space, both in the air and on surfaces.
