Standard 188P, Prevention of Legionellosis Associated with Building Water Systems, specifies what must be done to control the spread of legionellosis. The standard helps facility managers/owners understand how to effectively apply the available information on legionella in order to prevent cases of legionellosis associated with their building water systems.

The proposed standard underwent an earlier public review in June 2011 and is currently open for a third public review until March 11. For more information, visit www.ashrae.org/publicreviews.
