Looking for Aerosol Fogging Disinfectants?
You're not alone. The convenience of using aerosol fogging disinfectants does not require explanation. However, paying $8.00 - $15.00 per can will become costly.
There's an alternative and the option makes much more sense.
Most custodial operators, using aerosols for disinfection, do not swab to test surfaces in order to confirm the result of their efforts. (see ATP Testing)
Recognize that most disinfectants require up to a 10 minute dwell time to be effective. An aerosol in a typical room at 70 degrees F. will evaporate out within 1 - 2 minutes. That means that your efforts will fail at disinfecting. Similarly, setting off your foggers in a school bus, or ambulance during warm/hot weather, is a total waste, that results in failure.
Please read the label on your disinfectant label for dwell times required. Also note that instructions require pre-cleaning the surface, prior to disinfecting. A product used to clean and disinfect in one-step, cannot be effective without a full dwell time. - That's why we see secondary infections in medical and institutional facilities.
Your alternative is to use a fogging device, or electrostatic sprayer that can discharge your disinfectant with a particle size of 40 - 80 microns.
We'll focus on the Hurricane Ultra II Fogger for this report. The Hurricane II allows for a full gallon of disinfecting solution to be applied. - (Contemplate that your aerosol can, including 1/3 propellant, has a maximum available content of 8 ounces.) The economical savings and the opportunity to utilize greater disinfectant coverage should be apparent.
We're writing this article in late April 2021. The pandemic is still amongst us and the virulence can not be denied. The correct procedures and protocols must be in place to protect your facilities.
A person with the correct procedural skills and inferior chemistry will fail at disinfection. A person with the correct chemistry, without procedural skills, will also fail. It's the marriage of the two, in order to achieve the sanitation necessary to protect your environment.
