How Does COVID-19 spread?

COVID-19 is primarily transmitted through respiratory droplets, which are expelled into the air when an infected person coughs, speaks, sneezes, or sings. If air is not diluted properly indoors, the virus has the potential to remain suspended in the air for up to 16 hours and can fall onto surfaces and survive for up to 72 hours.

In fact, almost all cases of COVID-19 have been traced back to indoor areas and many researchers believe this is due to poor ventilation in buildings. This is why it is so important to keep exposure of the virus to a minimum, by working with qualified engineers who will provide trusted solutions. 

What can I do to prevent the spread on COVID-19?

We cannot rely on humans to always wear their masks, cover their mouths, wash their hands or keep proper social distance. It’s necessary to have air systems you can rely on, as they can protect against human error and are a supplemental COVID-19 prevention measure.

Therefore, the Health and Saftey Executive, World Health Organisation, Center for Disease Control and other governing bodies, are now recommending that each building’s systems be inspected and treated by a professional before any occupants re-enter and also encourage increasing ongoing maintenance, as a necessary form of prevention.

The most important thing you can do right now, is to increase your building ventilation rates. The American Industrial Hygiene Association recommends increasing the number of air changes per hour in a building to at least 6-12 changes per hour in medical environments, as it can reduce risk by 90%. You can find the full AIHA COVID-19 Guidance Document here.

Non-medical environments may require less air changes per hour to produce the same effect and consulting with a professional at Comfort Services Group will help determine how many air changes per hour your building needs. 

Our services and how they can help…

At Comfort Services Group, our engineers have been working tirelessly to protect our various clients in hospitals to dentist practices, from office buildings to film studios.

Our services include Air Change Rates to ensure your rooms air is properly diluted to prevent against the spread of COVID-19, remain fit for purpose, conform to regulatory requirements and that these ‘per hour’ rates are adhered to. We can also provide validation data and certificates. 

Further, Air Rate Testing and Validation of Air Change Rates, will ensure that your air systems are operating efficiently and are in-line with all legal and regulatory requirements. 

Air Tightness and Room Leakage Testing, allow us to monitor and report on the integrity of your room's construction. Air tightness testing will identify where unfiltered air may be entering your rooms and, therefore, compromising the intended protection against micro-particles and cross contamination. 

Lastly, Surface Swab Testing will help determine if the virus is on your building surfaces within 48 hours and will allow our professionals to work with you on best next steps for sanitisation. 

Get in contact with us here to protect against the spread of COVID-19 in your building today.

Wishing you good health and fresh air, 

Comfort Services Group

COVID-19: A guide to reducing COVID-19 in an office environment

As the COVID-19 pandemic continues, it remains essential to do all we can to reduce the spread of this dangerous virus. Since viruses can spread easily in office environments, so it is vital to take steps to prevent this and create safe and healthy workspaces for staff and visitors. Along with taking social distancing measures, employing stringent cleaning routines, and encouraging frequent handwashing, businesses are investing in professional ventilation cleaning to allow them to bring clean, fresh air into their offices.

COVID-19: Reduce the risk of exposure through ventilation

With COVID-19 still a significant risk to health in the UK, it is vital to take steps to limit its spread. One way to do this is to ensure that buildings are adequately ventilated. Ventilation is the process of bringing fresh air into indoor spaces whilst removing the stale air. Introducing fresh air to indoor spaces can remove air that is contaminated with virus particles, helping to prevent the spread of COVID-19. Ventilation systems should be maintained to a high standard to ensure they continue working effectively. Regular ventilation cleaning is essential for removing pollutants from the ductwork.
