Use UVGI when Ventilation & Filtration Options are Limited, Technical Instructions for Simulated Voyages by Cruise Ship Operators under CDC’s Framework for Conditional Sailing Order Suggest

“Consider using ultraviolet germicidal irradiation (UVGI) as a supplemental treatment to inactivate SARS-CoV-2, especially if options for increasing room ventilation and filtration are limited,” reently released Technical Instructions for Simulated Voyages by Cruise Ship Operators under CDC’s Framework for Conditional Sailing Order tell cruise ship operators. “Upper-room UVGI systems can be used to provide air cleaning within occupied spaces, and in-duct UVGI systems can help enhance air cleaning of recirculated air inside central ventilation systems.” A copy of the Center for Disease Control’s Technical Instructions released last month are available at https://www.cdc.gov/quarantine/cruise/instructions-local-agreements.html and were filed as an Exhibit in…
