Reduce COVID-19 Risk


Transmission of COVID-19 through the air and HVAC systems is likely. Therefore, it’s been recommended that changes to your building operations be made to reduce your exposure. These operations include: 

  • Making certain your systems are functional and operating normallduring the “stay at home” period and having them inspected and treated by a professional before occupants re-enter a building. 
  • Performing Air Rate Testing and Validation of Air Change Rates to ensure your systems are operating efficiently and in line with all legal and regulatory requirements. 
  • Increasing your Air Change Rates per hour, as this can reduce airborne particles in a room up to 90%. Medical environments should implement 6-12 changes per hour. Non-medical environments may require 4-8 changes per hour, but it is best to consult with a professional about the appropriate amount.
  • Conducting Air Tightness and Room Leakage Testing, which allows us to monitor where unfiltered air may be entering your rooms, therefore compromising the intended protection against micro-particles and contamination. 
  • Ensuring proper Air Filtration and Sanitisation in your building. If your filters are not within acceptable operating ranges, not working properly, damaged or dirty, there is a higher chance that they will not successfully catch airborne particles.
  • COVID-19 can remain suspended in the air for up to 16 hours in indoor environments. If air is not properly diluted, it can land on surfaces and stay alive for up to 72 hours. Surface Swab Testing will help determine if the virus is on your building surfaces within 48 hours and will allow professionals to work with you on best next steps for sanitisation. 
  • Maintaining appropriate indoor temperatures to minimise thermal stress on bodies, which can increase irritation and spread of the virus. 
  • Implementing ongoing maintenance of your systems to guarantee optimum performance during this time. 
  • If you notice poor air quality, (i.e. Stagnant or stuffy air, foul smells or thermal discomfort) reach out to a professional who can help resolve the issue as soon as possible.
