Open for Comment: Proposed ASHRAE Standard on Legionellosis Risk Management

Published October 8, 2014

Proposed ASHRAE Standard 188P, Legionellosis: Risk Management for Building Water Systems, is open for comment for its fourth public review through Nov. 10, 2014. According to ASHRAE, Standard 188P will establish minimum legionellosis risk management requirements for building water systems, and 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.

Since the proposed standard’s last public review in January 2013, ASHRAE has revised its title, purpose, and scope; removed hazard analysis and critical control points terminology; included an appendix for healthcare facilities meeting specific requirements that provides an alternate, more stringent compliance path; and placed more emphasis on requirements for design, construction, installation, commissioning, operation, maintenance, and service.

The latest public review draft is available as a PDF. For more information on ASHRAE’s proposed standard or its public review process, please visit the ASHRAE website.
