How effective are fogging machines in tackling the Covid-19 menace?

Infections in care homes and other social care settings can have a negative impact on society's most vulnerable members, including those who care for and support them. What control measures can managers put in place to mitigate the spread of COVID-19 with a prevalent virus that scientists are still learning about and a vaccine promised but not yet available to combat the spread?

The Covid-19 Menace

COVID-19 reproduces extremely quickly, with droplets from coughing, sneezing, and saliva droplets from human mouths spreading to whatever they come into contact with. When a person with COVID-19 coughs, sneezes, or talks, droplets containing the virus can be spread a short distance and quickly settle on nearby surfaces.

Fomite transmission occurs on a variety of surfaces, including door handles, computer equipment, touch screens, and handrails. If you touch those surfaces or objects and then touch your mouth, nose, or eyes, you could become infected with the virus.

According to studies, the new coronavirus can survive for up to 72 hours on plastic and stainless-steel surfaces, and for up to 24 hours on cardboard. With this in mind, the best way to prevent COVID-19 is to practice strict hygiene measures, such as cleaning and disinfecting surfaces and objects that people frequently touch, while we wait for the vaccines to be released.

How Fogging is Useful?

Deep cleaning can be done in a variety of ways. Fogging is a method for deep cleaning in kitchens that has been extended to offices, care settings, and industry. Fogging is done by a professional who uses specialized products and cleaning methods. Fogging uses an antiviral disinfectant solution (to BS EN 14476 standards) to quickly and effectively clean and sanitize large areas of a building. In the air and on surfaces, it can kill the virus and other biological agents.

The task entails spraying a fine mist with a spray gun and then allowing it to evaporate for 6 hours. The contactor must wear a chemical suit, gloves, an air-fed ventilator, and a sealed mask, among other things, to complete the task. When using the fog, mist, or vapor method, the contractor must ensure that the active chemical is used in the correct concentration.

This means there's enough for it to work properly, but not enough to leave a residue that could be hazardous for a long time after treatment is finished. The product used is safe for printers, computers, and other electronic devices because the mist is extremely fine, but it is still effective in penetrating all areas to kill the virus. The contractor, on the other hand, will discuss this with the client. However, it may not be appropriate for rooms that are difficult to seal.
