Resources available to address Legionella threat

Scientists and health professionals are warning building owners to heed the risk of Legionella prior to reopening buildings after COVID-19 pandemic shutdowns.

The risk of this deadly disease is elevated after extended shutdowns because stagnant water in HVAC systems can be a breeding ground for the Legionella bacteria. NSF Health Sciences and the National Environmental Health Association (NEHA) are hosting a virtual special session of the annual Legionella Conference on March 9-10, 2021.

“This virtual event will provide opportunity for experts from leading organizations to share insights and global perspective on an interactive platform,” according to a news release. “Specific topics include technical risk management and sampling strategies, safe reopening of buildings, and state-issued COVID-19 guidance related to water management, emergency planning and resiliency strategies to return to normal operations and prevent further public health hazards during a crisis.”

Online resources are available now at the CDC (https://www.cdc.gov/coronavirus/2019-ncov/php/building-water-system.html) and NSF Health Sciences (https://www.nsf.org/knowledge-library/covid-19-and-its-effect-on-your-building-water-health) web sites.

New York City has two very large buildings dedicated to answering the 911 calls of its five boroughs. With more than 11 million emergency calls annually, it makes perfect sense. The second of these buildings, the Public Safety Answering Center II (PSAC II) is located on a nine-acre parcel of land in the Bronx. It’s an imposing 450,000 square-foot structure—a 240-foot-wide by 240-foot-tall cube. The gleaming aluminum cube risesthe equivalent of 24 stories from behind a grassy berm, projecting the unlikely impression that it might actually be floating. Like most visually striking structures, the building has drawn as much scorn as it has admiration.
