ASHRAE Guideline 12 is intended for use by owners of human-occupied buildings and those involved in the design, construction, installation, commissioning, management, operation, maintenance, and service of centralized building water systems and components.
South Bronx hospital adopts new anti-microbial cooling tower technology to stave off Legionnaires' Disease
July 23, 2018
Legionnaires' disease is a severe form of lung infection caused by exposure to bacteria known as Legionella. Found naturally in freshwater environments like lakes and streams, Legionella becomes a health hazard when it grows unabated in water that is not properly treated. While this can include shower heads, hot tubs, and hot water heaters, cooling towers are often found to be the source of outbreaks.
Spartan Bioscience announced scientific results from a Legionella testing study of Canadian federal government buildings. The 12-week study tested 51 cooling towers in Ottawa, Toronto, and Montreal and compared weekly on-site Legionella DNA testing vs. monthly Legionella culture testing. Legionella DNA testing was performed with the Spartan Legionella Detection System.
Spartan Bioscience today announced the product launch of the Spartan Legionella Detection System. It is the first on-site DNA test for Legionella and it can detect and quantify Legionella bacteria in 45 minutes. The system consists of a coffee-cup-sized, portable DNA analyzer called the Spartan Cube® and a single-use disposable test cartridge.
The CDC study screened 196 cooling towers around the U.S. and found Legionella DNA (indicating the bacteria were there, live or dead, at some point) in 164 of the towers sampled and live Legionella bacteria in 79 of them.
Innovative design hinders the growth of hazardous cooling tower-borne pathogens
July 24, 2017
A new Center for Disease Control and Prevention (CDC) study involving 196 cooling towers nationwide found that 84 percent contained Legionella DNA, indicating that the dangerous bacteria that causes a severe, even fatal type of pneumonia were present or had been at some point. This means the real question is not “whether there will be another outbreak” but only “where and when” it will occur.
Presentation titled Following ASHRAE 188 with Limited Time, Money, and Personnel
December 16, 2016
HC Info will host a live online discussion about pressure facing building operators in the U.S. to comply with ASHRAE Standard 188 regarding Legionella risk, and on health departments to establish regulations.
The European collaborative Poseidon project says it has developed a scanner that can detect Legionella bacteria in under one hour, rather than the 10 days of cultivation and analysis normally required.
