A Strategic View of ASHRAE Standard 188 & Legionellosis in the Healthcare Environment


Presented by Helen Cerra, Technical Consultant, ChemTreat

Thursday May 11, 2017; 10:00 AM

Legionellosis is a health and safety concern for facility owners and operators, and for those who design, manage, and oversee building water cooling systems.  This concern entered the spotlight last year due to a Legionnaires’ disease outbreak in the Bronx borough of New York City. Only weeks prior to this large outbreak claiming lives and affecting over one hundred residents, ASHRAE published the first US standard addressing Legionella in building water systems. An ANSI consensus standard with input from practitioners, experts and several industry organizations, ASHRAE Standard 188-2015, titled “Legionellosis, Risk Management for Building Water Systems”, establishes the minimum legionellosis risk management requirements for the design, construction, installation, commissioning, operation, maintenance and service of centralized building water systems and components. This presentation outlines the history of the standard, principles of ANSI/ASHRAE standards development and the structure and essence of ANSI/ASHRAE Standard 188-2015. This standard has special impact on healthcare facilities, which often house immunosuppressed and other populations at higher risk of contracting legionellosis. This presentation has been developed by the Standard 188 committee as the official informational message, presented at ASHRAE chapter meetings by an executive committee member
