The desurface disinfection (DSVA) (AVSD) is a method of disinfecting the surfaces of a room. It consists of propelling a disinfectant product into the atmosphere using a diffuser.
The advantage of DSVA is that it does not require human intervention, so it can be carried out at night to avoid immobilising a laboratory, a food factory, a train, an office, a classroom or a nursery that must be operational during the day.
In addition, this method can be used to disinfect all surfaces in contact with the air. In fact, airborne surface disinfection (ASD)
Airborne surface disinfection (ASD) is carried out in a sealed room and the product will spread throughout the volume until it saturates the room with a dry mist.
How to ensure the efficiency of the process?
A standard, NF T 72-281, for FOGGING disinfection(DSVA), certifies the effectiveness of the diffuser/product combination. 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.
How is this Important Standard issued?
This French standard for airborne disinfection must be issued by a COFRAC (French Accreditation Committee) accredited laboratory. Here is the test room of the IRM laboratory accredited by COFRAC for the NF T 72-281 standard that our parent company IBL Specifik has obtained with its couple AIRBIO/APABIO and JETBIO/APABIO for all activities (bactericide, fungicide, virucide and sporicide).
