International. ASHRAE published a revised edition of its standard that provides a more comprehensive approach to preventing the growth and spread of Legionella.
The ANSI/ASHRAE Standard 188-2018, Legionellosis: Risk Management for the Construction of Aguam Systems sets minimum Legionellosis risk management requirements for the construction of water systems. The 2018 edition provides a clarification of compliance requirements, as well as an update of mandatory and coded language to facilitate the adoption of the standard for regulatory and code purposes.
The standard was originally developed to help building designers and operators establish water management plans that include practices specific to the systems that exist in a particular building, campus, or healthcare facility. It is intended to be used by those involved in the design, construction, installation, commissioning, operation, maintenance and service of water systems and components of centralized buildings.
"Standard 188 was the first industry standard in the U.S. to address the prevention of Legionnaires' diseases," said Paul Lindahl, chair of standard committee 188. "Since this standard focuses on the development and implementation of good design, operations and maintenance procedures, it is important to make updates on a regular basis. The 2018 edition of the standard focuses on improved usability, offering better guidance to minimize the risk of this life-threatening disease and save lives."
The 2018 edition of Standard 188 provides:
- A description of the environmental conditions that promote the growth of Legionella.
- Informative annexes and bibliography with suggestions, recommendations and references to additional guidance.
- Minimum Legionellosis risk management requirements for buildings and associated drinking and non-potable water systems.
- Requirements for Legionellosis control strategies and documentation.
