Background

While Legionnaire's disease has been known for many

years, recent outbreaks have increased awareness of the disease, its causes and prevention strategies

The Centers for Disease Control and Prevention (CDC): Estimates 8,000 - 18,000 cases of LD in the USA More than 10% of these cases are fatal ASHRAE providing information on Legionella since 1979

in response to the first Legionnaire’s disease outbreak in 1976 and the subsequent discovery by the CDC of the causative bacteria – Legionella

  • 1. Legionella: the name for the genus (a major

classification) of bacteria. Legionellae is the plural – referring to more than one Legionella bacterium.

  • 2. Legionellosis: any illness caused by the

exposure to Legionella. Legionnaires’ Disease (LD) and Pontiac Fever (PF) are the two most common types of legionellosis.

Potentially fatal, multi-system respiratory illness, accompanied by pneumonia Symptoms: high fever, chills, muscle pain, headache & dry cough; diarrhea, vomiting, confusion & delirium are also common Appears 2-10 days after exposure Recovery can be long-term & debilitating Susceptibility: ~5% (+/-) of those exposed

ANSI/ASHRAE Standard 188-2015

With 12 confirmed dead and more than 120 cases of infection due to legionellosis, New York City Council on Thursday adopted legislation that requires adherence to part of ASHRAE’s newly published Legionella standard. The legislation addresses registration and inspection of cooling towers. It requires owners to create and file a plan to maintain equipment to comply with Sections 5, 6 and 7.2 of the new ANSI/ASHRAE Standard 188-2015 / Legionellosis: Risk Management for Building Water Systems.

► ► ► ► PURPOSE: Establish minimum Legionellosis risk management requirements for building water systems.

► ► ► ► SCOPE: 1) … for design, construction, commissioning, operation, maintenance, repair, replacement, and expansion of new and existing buildings and their associated water systems 2) … applies to human-occupied commercial, institutional, multi-unit residential, and industrial buildings ... does not include single-family residential buildings 3) … for use by owners & managers of human-occupied buildings, excluding single-family residential buildings ... also for those involved in design, construction, installation, commissioning, operation, maintenance & service of centralized building water systems and components

ANSI/ASHRAE 188-2015

ANSI/ASHRAE Standard 188-2015

Compliance with Standard 188 will require facility owners (managers) to: 1

  • Establish a Team with assigned

responsibilities & accountabilities 2

  • Have, Practice, &

Audit a Water Management Plan for legionellosis risk management of their building water systems

Describe Water System Access the Hazard Establish Hazard Controls Audit the Plan

In a Nutshell

ANSI/ASHRAE Standard 188-2015

ASHRAE gives a framework, but the Team must develop specific LB control measures for:

  • New Construction
  • Siting
  • Startup and Shutdown
  • Inspections
  • Maintenance
  • Cleaning and Disinfection
  • Monitoring (e.g., temperatures; disinfectant

levels)

  • Water Treatment
  • Responding to Legionnaires' disease

  • The process or evidence used to support that the hazard control strategies of

the plan are effective. Testing for the control of the hazard or assessment of technical, scientific, medical and other data that can be used to show that control measures for the hazard are effective – i.e. no legionellosis;

…“Are you Doing the Right Thing – Does it Work?” Water Management Plan: VERIFICATION

  • The process and evidence used to support that compliance with the Plan is

being done – i.e. record-keeping, control monitoring, process procedures and

followed in practice;
