AIHA Offers IH Assistance on ASHRAE Standard on Legionellosis Risk Management

Posted November 12, 2014

Members of AIHA’s Indoor Environmental Quality Committee recently submitted comments on behalf of the association on a proposed ASHRAE standard on legionellosis risk management, offering to provide expertise in industrial hygiene to assist ASHRAE in the standard’s development. AIHA’s comments note that the current version of the standard ignores the fundamental principles applied by industrial hygienists that have proven effective in assessing and controlling workplace hazards.

“Industrial hygienists routinely conduct risk assessment of microbial hazards, aerosol hazards, and hazards associated with building systems,” AIHA’s comments read. “Our professionals are primary participants in both proactive and reactive investigations of legionellosis, and they are directly and materially affected by any guidelines or standards addressing the control of Legionella bacteria in building systems.”

AIHA believes that the current draft of the standard is likely to impose significant burden upon building owners and facility managers with inadequate assurance that it will substantially reduce the risk of human illness or mortality. The full comments are available on AIHA.org.

According to ASHRAE, Proposed ASHRAE Standard 188P, Legionellosis: Risk Management for Building Water Systems, will establish minimum legionellosis risk management requirements for building water systems. The proposed 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.
