Course Length: 3 hours

Legionellosis is a health and safety concern for facility owners and operators and those who manage and oversee building water cooling systems. ASHRAE Standard 188-2018 establishes the minimum legionellosis risk management requirements for the design, construction, installation, commissioning, operation, maintenance, and service of centralized building water systems and components. This course describes the environmental conditions that promote the growth of Legionella in water systems and the locations where Legionella control measures can be applied in new and existing buildings. A comprehensive management strategy for the prevention of legionellosis is also discussed. The course focuses on the compliance with ASHRAE Standard 188-2018 to provide a safer and healthier building environment.
