Just few days left to review ASHRAE’s proposed changes to Legionellosis Standard 188P for building water systems

ASHRAE’s proposed legionellosis standard is open for public comment until November 10, 2014.

Standard 188P, Legionellosis: Risk Management for Building Water Systems, currently under development, is intended for designers, building owners, and all others involved in the construction and operation of centralized building water systems.

Changes to the standard since its last public review in January 2013, include:


– An alignment of the document with the revised title, purpose and scope.

– The removal of hazard analysis and critical control points (HACCP) terminology; some of the principles of the HACCP process are consistent with the process utilized in the document.

– The inclusion of a normative appendix for health care facilities meeting specific requirements that provides an alternate compliance path that is more stringent than for other facilities.

– More emphasis on requirements for design, construction, installation, commissioning, operation, maintenance and service.
