ASHRAE 188 Information on Water Management Programs and Risk Assessments
ASHRAE Standard 188 provides detailed guidelines for the development and implementation of water management programs or plans and conducting risk assessments for Legionella to prevent Legionnaires’ disease:
- Water Management Program (WMP):
- ASHRAE 188 outlines the requirements for creating a water management program (WMP) for building water systems. This program is designed to identify hazardous conditions and take steps to prevent the growth and spread of Legionella bacteria.
- The WMP should be site-specific and include detailed descriptions of the building’s water systems, the risk factors, control measures, and verification processes.
- Risk Assessments:
- The standard emphasizes the importance of conducting a Legionella risk assessment as a critical component of the WMP. This involves identifying areas in the water system where Legionella could grow and spread, such as cooling towers, hot water systems, and decorative fountains.
- Risk assessments should consider factors like water temperature, stagnation, and the presence of biofilms.
- Monitoring and Control:
- ASHRAE 188 requires the implementation of monitoring strategies to ensure that control measures are effective. This includes regular testing of water systems for Legionella and documenting any corrective actions taken.
- The standard also provides guidance on the appropriate responses if Legionella is detected, including disinfection and remediation procedures.
- Team and Responsibilities:
- The ASHRAE 188 standard advises the formation of a water management team responsible for the development, implementation, and regular review of the WMP. This team should include individuals with knowledge of the building’s water systems, infection control, and risk management.
ASHRAE 188 is essential for building owners, managers, and maintenance teams aiming to manage Legionella risks effectively. It provides a structured approach to identifying, assessing, and mitigating potential risks associated with building water systems.
