Staying airborne and causing potential health issues when used in confined spaces such as vehicles and busses
50 micron sized particles sprayed at 5ft in the air will stay airborne for approximately 5 seconds
40 micron particles will stay airborne for approximately 8 seconds
30 micron particles will stay airborne for approximately 12 seconds
20 microns will stay airborne for approximately 24 seconds
10 microns will stay airborne for approximately 1 minute
As an example, the airflow created by a Sani-fogger can increase how long all of these particles stay in the air by 2-3x. This helps to provide greater coverage and increase coverage efficiency times. To address the smallest particles that stay airborne the longest, we’re looking at a maximum of a 3-minute period of time until the particles fall to the ground. Operators are trained to fog their way out of a home, school, or office, and this includes fogging their way out of vehicles or busses to minimize their exposure. They are directed to wear protective masks suitable for the chemical they are using.
After an area is treated, it is closed up and confined for 10 minutes to ensure that the chemistry has time to do its job of sanitizing or disinfecting. The 10 minutes serves two purposes: first, it provides a 3-4x safety factor for particles to drop, and second, after 10 minutes, even with internal air currents, there are not particles large enough in the air or concentrations great enough to affect even the most sensitive people as everything has had ample time to fall to the floor. Additionally, please bear in mind that as soon as doors or windows are opened, an air exchange occurs, replacing indoor air with outdoor air in as little as 1-2 minutes.
ULV electrostatic fogging with a Sani-fogger is icing on the cake of a really comprehensive decontamination procedure, and facilitates the greatest possible efficacy of COVID and other viral agent eliminators.
