The deaerial surface disinfection (DSVA) is a method of disinfecting the surfaces of a room. It consists of propelling a disinfectant product into the atmosphere through a diffuser.
Advantages of the DSVA
The interest of the DSVA - DISINFECTION OF SURFACES BY AIR DIFFUSION is the absence of human intervention, so it can be done at night to avoid immobilizing a laboratory, food processing plant, train or classroom that must be operational during the day.
In addition, this method disinfects all surfaces in contact with the air. Indeed, the DSVA, airborne disinfection, is carried out in an airtight room and the product will spread throughout the volume until the room is saturated by a dry fog.
How to ensure the efficiency of the process?
A standard, NF T 72-281, of airborne disinfection (DSVA)This allows the effectiveness of the diffuser/product combination to be certified. The standard makes it possible to determine the bactericidal, yeasticidal, fungicidal and sporicidal activity.
Be careful, a diffuser/product couple may have obtained satisfactory results for the bactericidal activity but not necessarily for the two remaining activities, fungicidal and sporicidal.
This French standard of airborne disinfection must be issued by a COFRAC (French Accreditation Committee) accredited laboratory. Here is the test room of the MRI laboratory accredited COFRAC for the NF T 72-281 standard that IBL Specifik has obtained with its couple AIRBIO/APABIO for all activities (bactericide, fungicide and sporicide).
