A fourth version of ASHRAE’s proposed Legionellosis standard is now open for public comment.
Standard 188P, Legionellosis: Risk Management for Building Water Systems, is under development. It will establish minimum legionellosis risk management for building water systems. This standard is meant for use by building owners and managers and those involved in the design, construction, installation, commissioning, operation, maintenance and service of centralized building water systems and components.
The standard will be accessible until Nov. 10. The draft and instructions on submitting comments can be found online at www.ashrae.org/publicreviews.
Changes to the proposed standard since its last public review in January 2013 include:
• Alignment of the document with the revised title, purpose and scope;
• 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;
• 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; and
• More emphasis on requirements for design, construction, installation, commissioning, operation, maintenance and service.
