BWI Thurgood Marshall Airport has earned the Global Biorisk Advisory Council’s (GBAC) STAR accreditation, the industry’s gold standard for clean and safe public facilities. As verified by GBAC, BWI Marshall has applied the most stringent protocols for cleaning, disinfection and infectious disease prevention.

As the cleaning industry’s only outbreak prevention, response and recovery accreditation, the GBAC STAR helps organizations establish cleaning procedures, offers expert-led training and assesses a facility’s preparedness. The certification verifies that BWI Marshall implements industry best practices to prepare for, respond to and recover from outbreaks and pandemics.

GBAC is a division of ISSA, the worldwide cleaning industry association. The GBAC accreditation is reserved for organizations that demonstrate a superior commitment to healthy, clean operations.
