Airborne Surface Disinfection (ASD) relies on the diffusion of a decontamination agent within a closed volume in order to treat the surfaces present in the area. However, implementing a cycle requires verifying several parameters related to the room, the equipment and the process conditions.

Understanding the principles of ASD
ASD consists of diffusing a decontamination agent into the air of a volume in order to treat the surfaces present in the room. This process is used in various controlled environments to reduce microbiological contamination on surfaces.
The performance of the cycle depends on several parameters. The configuration of the room, air circulation or the presence of equipment may influence how the decontamination agent diffuses within the treated volume.
Preparing the room before an ASD cycle
Before starting a decontamination cycle, several elements of the room can be analyzed to verify that the conditions are suitable for the process.
Checking the conditions of the treated volume
ASD relies on the diffusion of a decontamination agent within a closed volume. The sealing of the room and the containment of the volume therefore directly influence how the cycle proceeds. Uncontrolled air exchanges may modify the diffusion of the product or cause dispersion outside the treated area. These parameters must be taken into account when preparing the room.
Identifying surfaces and equipment present
Controlled environments often contain various technical equipment and structures. These elements may influence air circulation or the diffusion of the decontamination agent within the room. Analyzing the configuration of the room helps better understand how the product may distribute within the treated volume.

Checking the parameters of the decontamination cycle
Implementing ASD also involves observing certain parameters related to the process itself.
Observing the diffusion of the decontamination agent
During an ASD cycle, the decontamination agent diffuses in the air of the room. The distribution of the product within the volume depends on several factors, such as the configuration of the room or the presence of equipment. These elements may create areas where exposure to the product differs. Observing the treated volume helps better understand these variations.
Evaluating cycle effectiveness
In some contexts, biological indicators may be used to evaluate the microbiological effectiveness of a decontamination cycle. These indicators help observe the ability of the process to reduce a microbial population under defined conditions.
Learn more about ASD implementation conditions
Implementing ASD depends on several technical parameters related to the room and the process. Some aspects can be analyzed in more detail in order to better understand the cycle conditions.
Sealing and containment: essential conditions for effective ASD
Room sealing and volume containment directly influence the diffusion of the decontamination agent during a cycle. Controlling air exchanges helps maintain process conditions within the treated area.
Placement of biological indicators in ASD: methodology and critical points
Biological indicators may be used to evaluate the microbiological effectiveness of ASD. Their position within the treated volume can influence the analysis of the results obtained after the cycle.
Material compatibility in VH₂O₂ ASD: risks, limits and precautions
The compatibility of surfaces and equipment present in the room is also an important aspect when performing ASD using vaporized hydrogen peroxide (VH₂O₂).
