Portable VPHP Decontamination for Mobile and Field Laboratories

Mobile laboratories make it possible to bring diagnostic and research capability closer to an outbreak, surveillance programme or remote operation. They also introduce a practical biosafety problem: critical equipment may need bio-decontamination where there is no permanent installation or local specialist service.

A portable VPHP decontamination system can support a controlled process for suitable enclosed equipment and defined spaces. The point is not simply to move a generator. It is to bring a repeatable, documented process to the point of operation, so it works as expected no matter the circumstances.

Where mobility changes the operating model

Field and mobile laboratories can be deployed in vehicles, containers, temporary facilities or remote sites. Their workflows may change quickly and equipment may be relocated between missions. In these conditions, a fixed bio-decontamination installation can be impractical or unavailable.

Portable capability is especially relevant when teams need to:

• prepare a biosafety cabinet or isolator for maintenance, relocation or return to service;

• support a temporary diagnostic or surveillance workflow;

• control contamination risk between deployments or changes of use; and

• retain evidence of the cycle without depending on permanent building infrastructure.

Delox Box is designed as a compact, plug-and-play VPHP bio-decontamination system for critical enclosed equipment. Its integrated cycle management software, configurable cycles and remote start capability are intended to support controlled operation where the equipment is deployed.

Portability does not remove validation requirements

The setting may be temporary, but the process must not be improvised. Before deployment, the responsible organisation should define the equipment, the objective, the cycle configuration, the monitoring approach, aeration conditions and release criteria.

Biological and chemical indicators, concentration or residual hydrogen peroxide vapour measurements where appropriate, and cycle records all have a role. The correct evidence depends on the application and risk assessment. A successful cycle in one cabinet, vehicle or temporary enclosure should not automatically be assumed to apply to another configuration.

What to assess before selecting a system

Teams should assess more than nominal portability:

• Equipment compatibility: cabinet, isolator or enclosure type; filters; installed instruments and materials.

• Deployment conditions: power, temperature, humidity, access control, sealing and ventilation arrangements.

• Operator workflow: setup, cartridge handling, training, alarm response, documentation and escalation.

• Safe release: aeration method, residua hydrogen peroxide vapour verification and release authority.

• Logistics: transport, consumables, maintenance support and the ability to move between sites without disrupting readiness.

The most useful portable system is one that can be integrated into a field SOP before the next mission, not one that requires a new operating model each time it arrives on site.

A practical route to deployment

Start with one representative asset. Map the workflow from last use to release, including who owns the equipment, who starts the cycle, who reviews the result and how records are retained. Then test the most demanding credible configuration before rolling the process across multiple sites or units.

Evidence basis

The operational considerations in this guide are informed by research on controlled hydrogen peroxide-vapour generation, deployment of mobile hydrogen peroxide systems, and the influence of delivery conditions on process performance [1-3]. They do not replace application-specific validation.

Frequently asked questions

Can a portable VPHP system be used in a mobile laboratory?

It can support bio-decontamination of suitable enclosed equipment or defined applications in a mobile laboratory, subject to site-specific risk assessment, cycle development, monitoring, aeration and safe-release controls.

Does portable operation eliminate the need for validation?

No. Portability changes deployment logistics, not the need to demonstrate a repeatable process for the specific equipment and configuration.
