COVID-19: Are you ready for the next normal?


ASHRAE Fourth Full Publication Legionella Standard 188P - Cogency Team

Preventing legionellosis is an increasing health and safety concern for building owners and facilities managers.

The American Society of Heating, Refrigeration and Air-Conditioning Engineers, Inc. (ASHRAE) has released a 4th draft of Standard 188 – Legionellosis: Risk Management for Building Water Systems, for public review.  The purpose of ASHRAE 188P is to establish standard practice for preventing legionellosis associated with building water systems.  The recent draft provides practical methods specific to the building industry in order to control rapid growth and prevent human exposure to the Legionella bacteria.

There are several changes to the proposed standard including:

  • Alignment of the document with the revised title, purpose and scope.
  • Removal of hazard analysis and critical control points (HACCP) terminology; some of the principles of the HACCP process are consistent with the process utilized in the document.
  • Inclusion of a normative appendix for health care facilities meeting specific requirements that provides an alternate compliance path that is more stringent than for other facilities.
  • More emphasis on requirements for design, construction, installation, commissioning, operation, maintenance and service.

In short, when finalized, ASHRAE 188 will highlight how facility managers/owners approach risk management and the prevention of Legionellosis.
