FACS would like to invite you to join John Martinelli, primary author, and fellow moderator Steven A. Pergam in the education session: “2305 – ANSI/ASHRAE Standard 188-2015, Legionellosis: Risk Management for Building Water Systems, Bridging Gaps between IPs, Engineering and Construction” at the upcoming 2016 APIC Conference in Charlotte, NC. The session is on June 12 from 1:30-2:30.

Course Description:

Outbreaks of nosocomial legionellosis (aka Legionnaires’ disease) attract great attention. Up to 30 percent of healthcare-associated pneumonia is caused by Legionella bacteria. Waterborne bacteria such as legionella are ubiquitous in water systems. They are commonly present in the water supply, generally in small numbers, but are easily amplified in the hospital’s hot-water systems. Amplification is impacted by temperature, chemistry, biology, and flow. Proactive control can be costly and requires considerable attention to detail. Decontamination of an unhealthy system is even more expensive and difficult. While the costs to design and build a healthy system can be high, they are insignificant compared to the cost of human health suffering and subsequent treatments once an infection occurs. The ANSI/ASHRAE Standard 188-2015, Legionellosis: Risk Management for Building Water Systems, adopted on June 25, 2015, provides a framework for managing building water systems to prevent the growth of harmful bacteria. The standard places a burden on the owner to develop a comprehensive program that includes identifying areas of risk, implementing methods to mitigate those risks, and measuring to prove the effectiveness. Case studies will demonstrate how a multidisciplinary team during for construction and renovation projects can meet the requirements of the ANSI/ASHRAE Standard 188-2015, including the commissioning requirements of Section 8.4. We will also see how, by not following these team driven processes, illness can occur and how determining the origins and effective treatments of the systems can be complicated and costly. The session will discuss the roles of team members including building designers, plumbing engineers, the owner, the engineer that will inherit the building, infection preventionists, project managers, water systems treatment vendors, and testing consultants. The session will also address the complex topic of program validation and verification, including the value and limitations of various laboratory and on-site analysis options.

Learning Objectives:

  • List the key participants on the multi-disciplinary team that are needed to ensure the system risk are identified and mitigation measures are effectively implements
  • List at least four elements of ANSI/ASHRAE 188-2015 that can be used to design and build healthy building water systems
  • List benefits and limitations of at least three different analytical methods used to validate effectiveness of controls
