Antimicrobial Copper Takes Off
One of Brazil's busiest airports is leading the way in
improving hygiene in public spaces with a new installation of
antimicrobial copper touch surfaces, including handrails and

Around 80% of infections are spread by touch,
the installation of Antimicrobial Copper components is
intended to help protect the airport's travelers by reducing
the bacteria that resides on commonly touched surfaces.
Antimicrobial Copper rapidly kills bacteria that settle on its
surface. This property is inherant to both copper
and alloys which contain at least 60% copper by weight, such
as brasses, bronzes and copper-nickels. Antimicrobial
Copper's efficacy has been proven in healthcare environments,
leading to its installation in hospitals around the world, and now
its applications are being explored more widely.
In December 2011, new parking areas were opened at Congonhas
Airport, handling around 4,000 vehicles and 10,000 people every
day. The opportunity to upgrade handrails, counter tops and
elevator guardrails to Antimicrobial Copper was seized by the
airport, and microbial testing of the surfaces has already shown a
significant reduction in contamination.
Initial tests on the copper surfaces revealed residual bacterial
contamination levels of less than 10 colony forming units (CFUs)
per cm2. On equivalent surfaces made of stainless
steel, this figure could be as high as 800 CFUs.
In addition to a very modern and striking aesthetic,
Antimicrobial Copper is continuously reducing the level of
contamination - in between normal cleaning procedures - and helping
to reduce the risk of travellers exchanging infections as they pass
through this busy transport hub.
