ASHRAE announced the approval of its anticipated pathogen mitigation standard, ASHRAE Standard 241, Control of Infectious Aerosols. This groundbreaking standard is a major step forward in reducing the risk of infectious disease spread in buildings.
ASHRAE Standard 241, Control of Infectious Aerosols, establishes minimum requirements aimed at reducing the risk of disease transmission through exposure to infectious aerosols in new buildings, existing buildings, and major renovations. The implementation of this standard brings numerous benefits to occupants and promotes healthier environments.
Infectious aerosols, which are microscopic particles exhaled by individuals, can carry disease-causing pathogens. These particles are so small they can linger in the air for extended periods and pose a risk when inhaled. By adhering to Standard 241, building owners and operators can effectively reduce exposure to various pathogens, including the SARS-COV-2 virus responsible for COVID-19, as well as influenza viruses and other disease-causing agents that inflict significant personal and economic damage each year. The standard encompasses a wide range of requirements covering air system design, installation, operation, and maintenance.
Other highlights include:
- Infection Risk Management
Reduction of Disease Transmission Risk
Comprehensive Air System Considerations
