ASHRAE completes infectious aerosols standard

USA: ASHRAE has approved for publication its much-anticipated airborne infection risk mitigation standard, described as a major step forward in reducing the risk of infectious disease spread in buildings. 

ASHRAE Standard 241, Control of Infectious Aerosols establishes minimum requirements to reduce the risk of disease transmission by exposure to infectious aerosols in new buildings, existing buildings, and major renovations. 

Infectious aerosols are tiny, exhaled particles that can carry disease-causing pathogens and are so small that they can remain in the air for long periods of time and be inhaled. It is said that use of this standard would reduce exposure to SARS-COV-2 virus, which causes covid-19, influenza viruses and other pathogens that cause major personal and economic damage every year. Standard 241 provides requirements for many aspects of air system design, installation, operation, and maintenance.

“Standard 241 represents a significant step forward in prioritising indoor air quality,” said ASHRAE President Farooq Mehboob. “By implementing the requirements outlined in this standard, we can improve the health, well-being and productivity of building occupants. This standard empowers building owners, operators and professionals to take proactive measures in safeguarding indoor environments. It’s an essential tool for creating healthier indoor environments and promoting sustainable practices.”

Standard 241 is now available for presale in the ASHRAE Bookstore.
