ASHRAE Standard 188-2015, Legionellosis: Risk Management for Building Water Systems was officially published by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) in 2015. Globally recognized for its industry leadership in providing technical information, ASHRAE, accredited by the American National Standards Institute (ANSI), develops standards for the design and maintenance of indoor environments.
Created to reduce the occurrence of Legionella in human-occupied, building water systems, the ASHRAE Standard 188 addresses the design, construction, installation, commissioning, operation, maintenance and service of centralized building water systems and components to manage the risk of this bacteria.
The ASHRAE Standard 188 provides essential guidelines for decreasing the risk of Legionella occurrence associated with the contaminated water systems of the human-occupied buildings, recommending a preventative approach in all stages of building design, construction, operation, and maintenance.
Based on the Hazard Analysis and Critical Control Points (HACCP) principles, the new standard is a very useful tool to help you identify and analyze each potential risk of microbial contamination in the water system by a management team. The ASHRAE Standard 188 lists the most important components of the water systems that can increase the risk of developing this devastating disease in current or future residents of your building.
How can you comply with ASHRAE Standard 188? Compliance requirements include:
The requirements of the ASHRAE Standard 188 enhance the development of a rigorous preventive program based on the experience accumulated with the HACCP principles. The implementation of the standard in a building construction project or in the management of a human-occupied building ensures all the prerequisites for the decrease of the Legionella occurrence risk in the residents or future residents.
