ASHRAE Releases Legionellosis Standard for Review
A fourth version of ASHRAE’s proposed legionellosis standard is open for public comment until Nov. 10.
Standard 188P, Legionellosis: Risk Management for Building Water Systems, currently under development, will establish minimum legionellosis risk management requirements for building water systems. The standard is intended 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.
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.
- More emphasis on requirements for design, construction, installation, commissioning, operation, maintenance and service.
Earlier this month ASHRAE proposed an alternate compliance path for existing buildings in its indoor air quality standard.
