Choosing a DSVA system with VH₂O₂ requires a structured analysis. The choice depends on the volume to be treated, the room’s sealing, and the expected level of automation. Cycle documentation and parameter traceability play a central role in regulated environments. A suitable system facilitates the implementation of a reproducible cycle. It also supports the integration of the process into the site’s quality system.
Define the volume and configuration of the room
A DSVA system must correspond to the actual volume to be treated. The volume depends on the size of the room, but also on its configuration. A room may contain equipment, work surfaces and technical areas. These elements influence the circulation of the VH₂O₂ dry fog. The cycle must therefore remain consistent with these constraints.
Nominal volume and usable volume
Nominal volume corresponds to the theoretical volume of the room. Usable volume corresponds to the volume actually treated. The presence of equipment may reduce the available space. It can also modify product dispersion. A preliminary analysis helps limit discrepancies between the defined cycle and the actual cycle.
Exposed surfaces and difficult-to-reach areas
DSVA acts on exposed surfaces. Some areas remain more complex to treat. These may include corners, spaces behind equipment or compartmentalized volumes. The cycle must take these constraints into account. The system selection must therefore reflect the real configuration of the room.
Check sealing and containment capacity
DSVA is carried out in a closed volume. Room containment is therefore a critical factor. A leak may alter the concentration reached. It may also disrupt the stability of the cycle. The site must therefore verify room sealing before implementing the process.
Sensitive points within the room
Sensitive points are often located at doors, seals and technical interfaces. Cable passages, ducts and certain access panels may create leaks. A preliminary verification helps identify these areas. It then facilitates the definition of a stable cycle.
Ventilation and cycle conditions
The site must manage ventilation according to internal protocols. Some cycles require a specific room configuration. This factor influences VH₂O₂ dispersion and the aeration phase. The selected system must remain compatible with these requirements.
Choose an appropriate level of automation
Critical environments require reproducible cycles. Automation supports this requirement. An automated system controls the different phases of the cycle. It limits variations related to manual interventions. However, the level of automation depends on the context and internal requirements.
Control of cycle phases
A DSVA cycle includes an injection phase, an exposure time and an aeration phase. An automated system helps structure this sequence. It also facilitates repeatability of operations. This consistency strengthens operational control.
Consistency of applied parameters
A cycle relies on critical parameters. Concentration, exposure time, temperature and relative humidity influence the result. The system must allow stable control of these parameters. This stability limits variations between cycles.
Evaluate cycle documentation and traceability
In regulated environments, DSVA requires structured documentation. The site must be able to record the parameters of each cycle. This traceability facilitates reproducibility. It also supports deviation management and audit preparation.
Recording of cycle data
Each phase must be documented. The site must be able to retrieve the parameters applied and the room conditions. This approach makes it possible to verify treatment consistency. It also facilitates analysis in case of deviations.
Archiving according to internal procedures
Data must be archived according to the site’s quality system. Structured archiving supports documentation control. It also facilitates the long-term use of information.
Integrate the system into a regulated environment
A DSVA system must integrate into an existing organization. The site manages procedures, quality requirements and operational constraints. The system selection must therefore take this reality into account. The process must remain consistent with a global contamination control strategy.
Consistency with site requirements
Each site defines its own criteria. These may include GMP requirements and internal rules. The DSVA system must integrate into this framework. It must allow clear and documented implementation.
Reproducibility of operations over time
A reproducible cycle strengthens operational stability. It supports consistency between interventions. It also reduces uncertainties related to variations in conditions. System selection should therefore favor a stable and structured approach.
