Health officials initially thought a flu bug was being spread among the convention attendees. At the time, all the symptoms presented themselves as flu-like. The symptoms included fever, coughing and difficulty breathing. ![]() Of those thousands of people attending the convention, around 600 of them were staying at the Bellevue Stratford Hotel.ĭuring the second day of the convention, some of the participants began falling ill. ![]() More than 4,000 World War II veterans, including friends and family, were congregating Philly as part of the 58th American Legion Convention. Legionella was first discovered at the Bellevue Stratford Hotel in Philadelphia following a meeting of the American Legion in July 1976. Then the standard can be finalized and published.Īs a member of the ASHRAE committee, we have been involved with discussions for revisions to the ASHRAE 188 standard and revisions to the soon-to-be-published next edition of ASHRAE Guideline 12, which is intended to support and compliment ASHRAE 188 with supplemental information on control of Legionella bacteria in building water systems. When it is complete, the “ANSI” designation can be added to the standard after ANSI verifies it followed the ANSI consensus development process. The standard is to be developed in accordance with ANSI requirements. I, along with several other committee members, also helped develop ASHRAE Standard 188, Legionellosis: Risk Management of Building Water Systems, which was initially published in 2015.ĪSHRAE Standard 188, is focused on control of Legionella bacteria in water systems, while NSF Standard 444 was intended to be a broader standard, covering prevention of injury and disease from many other waterborne pathogens.ĭuring a conference call in January 2019 to both committees, ASHRAE and NSF staff issued this statement: “ASHRAE and NSF International agree the ASHRAE/NSF 514 standard is urgently needed to assist regulators, public health departments, building owners and health-care facilities in better managing the risk of waterborne pathogens and hazards in building water systems.” The intent is for the new ASHRAE/NSF 514 standard to reference ASHRAE 188 for control of the Legionella bacteria in building water systems while it will cover many other common water-borne pathogens. A joint committee of stakeholders, of which I was a part of, developed the existing draft of NSF 444. The new ASHRAE/NSF Standard 514 will take the place of the standard previously known as NSF 444, which has been in development for a couple of years but not completed. The new standard will be known as ASHRAE/NSF Standard 514, Prevention of Injury and Disease Associated with Building Water Systems. ![]() ![]() The agreement will have ASHRAE serve as the lead sponsor with the responsibility for publication and maintenance of the new standard, and NSF International will serve as a joint sponsor. Recently, the American Society of Heating Refrigeration and Air Conditioning Engineers (ASHRAE) and the National Sanitation Foundation International (NSF International) announced they are in the process of finalizing an agreement to jointly complete a building water management standard for the prevention of injury and disease associated with building water systems.
