A fourth version of ASHRAE’s proposed Legionellosis standard has been released for public review and is available for comment until November 10, 2014.
ASHRAE’s Standard 188P, Legionellosis: Risk Management for Building Water Systems, seeks to establish minimum Legionellosis risk management requirements for building water systems.
The document can be viewed at www.ashrae.org/publicreviews.
According to Tom Watson, chair of the Standard 188P committee, “Building water systems vary substantially in their design and their capability for transmission of Legionella” and that “Scientific evidence is either lacking or inconclusive in certain aspects of Legionella control. The informative guidance is included to provide suggestions, recommendations and references.”
