Vancouver, Canada’s TransLink will be the first transit system in North America to pilot the use of bacteria and virus killing copper on high-touch transit surfaces. The project is part of a study that will see various copper-based products and a protective coating called organosilane installed on SkyTrain and buses to test how effective these agents are at destroying viruses and bacteria on transit.
There will be comprehensive testing as part of the initial four-week pilot phase:
- Products will be installed on two trolley buses on high-ridership routes and two SkyTrain cars on the Expo and Millennium Lines.
- Twice weekly the surfaces will be swabbed and tested to determine antimicrobial effectiveness of the products.
- At the end of one month, the surfaces will also be assessed for durability.
The results of this pilot could have wide-reaching impacts for infection prevention for the transit industry and other industries that rely on shared public spaces.
Copper alloy surfaces are naturally antimicrobial with self-sanitizing properties. Recent literature shows that copper alloy surfaces destroy up to 99.9% of bacteria and viruses within four hours. Organosilane is a wipe-on coating that can provide long-lasting protection against damaging microbes such as bacteria, mold, mildew, and many viruses. When used in tandem with good hygiene and cleaning protocols, copper and organosilanes can help inhibit the buildup and growth of viruses and bacteria.
The project is the result of a partnership between TransLink, Teck Resources Limited (Teck), Vancouver Coastal Health, VGH & UBC Hospital Foundation, Coalition for Healthcare Acquired Infection Reduction (CHAIR) Canada, and the University of British Columbia. The initial phase is fully funded by Teck, as part of its Copper & Health program. It is based on preceding studies conducted by the Infection Prevention & Control team at Vancouver Coastal Health and supported by Teck that have shown copper is effective at killing bacteria and is durable over a period of many years.
TransLink is aiming to make transit one of the safest public spaces throughout the pandemic and this measure builds upon the Safe Operating Action Plan. TransLink will continue to research, develop, and implement industry-leading practices on all modes of transit in Metro Vancouver.
