Risk Assessment For Air (Indoors).
Fighting Airborne Diseases - CORONAVIRUS & Influenza
Our software is FREE for anyone to use.
We all breath out Carbon Dioxide (CO2).
Anyone with coronavirus also breathes out coronavirus particles.
People breath in the coronavirus particles and become infected.
So we open windows to let coronavirus escape.
The CO2 also leaves the room!
So we measure CO2 in a room to check if windows are open enough.
Our software helps you understand how many windows to open.
Why not use a calculator?
Because mistakes can be made, see mistake in example at Harvard.
The answer is NOT 4.6
(We notified Harvard a few weeks ago but received no reply, and example is still wrong)
5 Steps of Risk Assessment..
1) The Size.
A typical classroom.
2) The Ventilation.

3) The Duration.
30-minute intervals, so risk level is 999.6
4) The Occupiers.
5 teenagers reading.
5) Adjust Occupancy Levels.
View Risk Assessment, Red Dot Is Danger.
Go back to any previous step and adjust until the red dots disappear.
In this example you might want to open a window at 08:30 and 11:30.
