LONDON--New biological decontamination technology for homeland security is reviewed in a webinar on July 8th 2010 at 16:00 hours BST (London), 11:00 EDT (New York). The on-line event explains how enclosed spaces – from homes and offices, to laboratories and public buildings - can now be protected in minutes from airborne and surface pathogenic viruses and bacteria.
The UK Government’s Health Protection Agency, Centre for Emergency Preparedness & Response, has independently tested the Tri-Air technology. Tests on a range of devices have shown kill rates to 99.9999% for airborne test virus MS2 Coliphage in under 5 minutes; 99.999% of airborne Staphylococcus epidermis within 2 minutes; and 99.9999% of surface MRSA on glass over a 24-hour period.
Registration for the CBRN event is free, at www.tri-airdevelopments.com. It is organised by Tri-Air Developments, co-founded by the UK's BRE (Building Research Establishment), microbiologists at Promanade Ltd and technology transfer specialists Inventa Partners Ltd
Counter-terrorism measures for biological threats have been limited to date in their scope and effectiveness by the constraints of available technologies, Tri-Air explains. The air filtration systems used were inherently slow, taking several hours or days to clean a room. Crucially, the process was usually unable to deal with surface contaminants - and spaces treated might never be considered to be completely safe.
Now Tri-Air has combined three separate air purification technologies to overcome inherent shortcomings of each individual process and eliminate the need for filtration. The result is a system combining non-thermal plasma, ultraviolet catalysis, and Hydroxyl Radical generation, offering up to 99.9999 per cent protection in minutes for airborne and surface pathogenic viruses and bacteria.
The overall effect simulates the natural purification properties of fresh air, Tri-Air Developments CEO Gideon Davenport explains: it creates the cleansing conditions that occur outdoors. This environment is lethal to viruses and bacteria - including H5N1, H1N1, Norovirus and MRSA - and continually decontaminates by a process of advanced oxidation.
"Tri-Air is now licensing the technology to manufacturers, integrators and other service companies supplying armed forces, airports, shopping malls, Government buildings, offices and domestic markets. The system offers protection for security and civilian staff, visiting clients and general public, from viruses, bacteria and CBRN bio-attack - even from the common cold," says Gideon Davenport.
