Hydrogen peroxide decontamination from MAT FM
– effective disinfection of sensitive areas
MAT FM is now able to offer hydrogen peroxide decontamination of operating theatres, recovery areas, critical care, sterile services, aseptic suites, cleanrooms and containment laboratories. It can be carried out by our trained service engineers prior to handover of a completed new build or refurbishment project, or as part of a regular periodic maintenance proposition, or as an emergency call-out. The system kills at least 99.99% of harmful bacteria, viruses, fungi and mould, and offers outstanding support to any infection prevention and hygiene regime.
It can be very difficult to decontaminate the specialist equipment and various surfaces in hospital and life science areas. However, the delivery system for the hydrogen peroxide vapour used in the process MAT FM offers reaches areas where traditional cleaning methods cannot, providing thorough and effective disinfection. It is non-corrosive so safe for use on electronic devices and equipment and can be used on all material types. This means that no special preparation is required before an area is vacated for decontamination. The system is also suitable for a positive pressure environment. These attributes make it ideal for the sensitive areas served by MAT FM, which often include equipment such as ultraclean ventilation (UCV) canopies, operating lights, delicate endoscopic or monitoring equipment, safety cabinets and high powered microscopes..
A key element of the system’s success is that it is touchless – while wiping spreads contamination from surface to surface, this innovative technology works on a ‘spray and walk away’ basis. The environmentally friendly decontamination method uses stabilised hydrogen peroxide (H2O2) and Silver (Ag), which breaks down into simple, 100% biodegradable, non-toxic water and oxygen. The hydrogen peroxide vapour is delivered via fogging for total area disinfection, or as a spray for surface disinfection. An oxidising agent, it destroys bacterial cell walls by stealing their electrons then leaves a safe and undetectable layer of silver ions on surfaces to prevent future contamination
MAT FM recently carried out hydrogen peroxide decontamination at Fairfield Independent Hospital, spraying everything in two theatre suites, plus recovery and adjoining areas, with medical equipment left in situ. The area was then fogged to ensure thorough disinfection.
o always kills 99.99% of harmful pathogens (4-log kill)
o achieves 99.999% on C.diff and Geobacillus (6-log kill)
• Quick: takes only a few minutes to treat a standard area

After completing several previous cleanroom and containment laboratory projects at Imperial College London, MAT was proud and excited to once again have the opportunity to work in partnership with such a prestigious institution to deliver the new research environments.
After initial designs were developed and approved, building work began in summer 2020 and the new cleanrooms were handed over in June 2021, the entire project having taken just 11 months.
Imperial College London is a global top ten university with a world class reputation. Its alumni include 14 Nobel Prize winners, including Sir Alexander Fleming.
To enable the highest level of research, the university offers the best
possible facilities. One of its flagship buildings is the £90m Sir Michael
Uren Hub, located at the White City campus. Designed as a
collaborative facility, the 13-storey Hub provides space for Imperial’s
world-leading researchers, engineers, scientists and clinicians to work
alongside one another to investigate some of the twenty first century’s
most urgent biomedical and healthcare problems.
FEATURES CONTAINED WITHIN THE CLEANROOMS:
The new cleanrooms MAT was commissioned to design and build both had to be ISO Class 6 standard to safely accommodate the semiconductor research that would be carried out in them. Class 6, as defined in ISO 14644-1:2015 Cleanrooms and Controlled Environments, refers to the cleanliness levels that must be met within the cleanroom.
In addition to having a high air change rate, an ISO 6 environment must be accessed through airlocks to preserve pressurisation differentials and prevent the migration of particles from outside into the cleanroom space, increasing one class at a time. So, users should pass through an ISO 8 environment, then an ISO 7 environment, before entering the ISO 6 cleanroom.
MAT acted as the designer and main contractor on the cleanroom project, working closely with the university to ensure minimum disruption to the other activities being carried out in the Sir Michael Uren Hub.
The team developed a design built around the complex research equipment and specialist tools that would be housed in the new cleanrooms. Work included final services connections and extensive bottled and house gases installation to several hazardous gases and associated gas detection systems.
HVAC design is complex and requires a highly skilled delivery team.
MAT is an expert in the provision of specialist HVAC systems. The HVAC system is at the heart of cleanroom design. Cleanroom HVACs differ from standard systems in that they have an increased air supply, different airflow patterns, use of high efficiency particulate air (HEPA) filters, and room pressurisation, and clean to dirty room air cascades.
In order to meet the required air cleanliness, the air must pass through HEPA filters. The lower the ISO class, the more often the air must pass through the HEPA filter. This ‘air changes per hour’ rate (ACH) and the room volume are used to calculate the HVAC’s required airflow. A conventional HVAC system usually makes two to four air changes per hour, whereas in a cleanroom it can range anywhere from 10 to 250 or even more.
The ISO Class 6 cleanrooms at Imperial College London require air change rates from 50 to 70 per hour.
MAT designs, manufactures and installs bespoke critical ventilation systems and turnkey project solutions for new build and refurbishment projects. As a specialist contractor with many years’ experience, we are passionately committed to improving patient protection and end-user safety in demanding clinical, research and drug production arenas.
We have extensive experience of working in live environments and understand the challenges around delivering a project within an operational scenario.
In addition, MAT FM provides a range of competitively priced and highly effective service and maintenance packages for all core products and turnkey solutions offered by MAT or other suppliers, ensuring that equipment is maintained, serviced and validated correctly for optimum performance.
