New Legionellosis Standard Provides Guidance on Risk Management
Most cases of legionellosis are the result of exposure to Legionella associated with building water systems
ATLANTA — Guidance for the HVAC industry on legionellosis is now available in a new standard from ASHRAE. The document establishes minimum legionellosis risk management requirements for building water systems.
“The industry interest and input into developing this standard has been tremendous,” said Tom Watson, chair of the committee that wrote the standard. “With 8,000 to 10,000 cases of Legionnaires’ disease reported each year in the United States, and with more than 10 percent of those cases fatal, it is vital that we set requirements to manage risk of this bacteria.”
