ASHRAE seeks input on HVAC market standard
Another version of ASHRAE’s proposed HVAC market standard for dealing with Legionnaires’ disease is open for public input.
The standard, known as No. 188P, “Legionellosis: Risk Management for Building Water Systems,” will offer guidance on dealing with the waterborne bacteria that can affect HVAC construction and sheet metal products.
The latest draft can be viewed here.
Drafting committee chairman Tom Watson said the American Society of Heating, Refrigeration and Air-Conditioning Engineers is attempting to create a HVAC construction standard that can act as a reference.
“Building water systems vary substantially in their design and their capability for transmission of legionella,” Watson said. “Scientific evidence is either lacking or inconclusive in certain aspects of legionella control. The informative guidance is included to provide suggestions, recommendations and references.”
The disease is named after an outbreak that occurred at a Philadelphia hotel during an American Legion convention in July 1976.
