Hughes has launched a powerful new portable decontamination system for the fast and effective treatment of CBRN hazards.

The compact back-pack comprises a Hughes ultrasonic atomizer spray and a specially formulated chemistry stored in a pressurised delivery system.

The company already offers a range of decontamination systems, and this latest addition is the result of collaboration with several partners specialising in biological and chemical treatments for CBRN and infection control. They have been optimized for use with the Hughes Atomizer for a wide range of hazards. Two formulations are available, one for CBRN, and a reduced strength for Infection control. Together with the Hughes Atomizer they offer a single versatile system for dealing with threats from the battlefield to the hospital ward - in fact, wherever there is a risk of contamination or infection.

A rechargeable compressed air cylinder within the back-pack provides the propellant to carry the chemical to the Atomizer nozzle for delivery as a fine spray on to the surface being treated. The spread and size of the spray can be adjusted according to the application. Atomizing the spray ensures effective coverage without the risk of excessive wetting. In addition to spraying directly on to contaminated surfaces, the Atomizer can be used to create a mist to capture airborne viruses.

The chemistry, MDF 200, has been developed by US specialist MODEC Inc., an established supplier of decontamination products. Hughes has worked closely with the European distributor, Health Pure Tech of France, to bring together the specially formulated chemical and atomizer delivery into a convenient, portable system. MDF 200 comprises a 2-part chemistry which is premixed and stored within the back-pack, remaining active for up to 8 hours. The system uses chemical and biological processes to encapsulate and safely supress contamination which may be deposited on surfaces or airborne. This process of containment reduces the risk of further dispersion, as in the case of radiation particles, and makes it easier to collect for safe disposal.

The MDF 500 formulation is half strength and intended for Infection Control applications. The chemistry has completed EEC testing and is suitable for treating a wide range of hazards such as the Norovirus, Anthrax and Avian Flu. It can also be used to treat mould or the potentially toxic residue from flood damage.

The chemical and delivery system employed in the new back-pack can also be used as part of the Hughes Self Sanitising Technology (SST) EndoStatâ„¢. This is a multi-stage anti-microbial treatment for cleaning, disinfection and protection. It is ideal for use in hospitals and wherever there is a risk of contamination. Surfaces are first cleaned and decontaminated using the back-pack chemistry and then the Hughes SST is used to spray on a protective coating to prevent future contamination. The inside of all new Hughes Tank Showers are now routinely treated in the factory with the SST to minimise the risk of Legionella occurring when the tank is filled with water on site.

As part of this integrated solution, particularly for hospital use, the complete system can be conveniently supplied within a standard hospital trolley, ensuring complete mobility and compatibility with existing cleaning and hygiene regimes. Where trolley access is limited, back-pack versions remain the best option enabling operators to take the treatment wherever it is required. For larger equipment such as trolleys and operating tables, a fully fitted demountable trailer is available. A series of fixed and hand-held ultrasonic spray guns deliver the various stages of the treatment as equipment passes through the trailer from dirty side to clean.

Decontamination is an on-going process, developing and refining products and techniques to combat not only current but emerging threats. Hughes works closely with Emergency Services to anticipate future needs and maintains a dialogue with End Users to optimise the performance of all products. If you would like to discuss specific requirements or any decontamination issues call Hughes because we believe that working together is the best way forward.
