MSIB: COVID-19 Safety Requirements in the Maritime Transportation System: Change-4

The Coast Guard Assistant Commandant for Prevention Policy has published Marine Safety Information Bulletin 02-21 Change 4 “COVID-19 Safety Requirements in the Maritime Transportation System”.

Change-4 to this MSIB reflects that the CDC has issued no new guidance for maritime travel and continues to require mask wear in indoor areas of conveyances and US transportation hubs. All previous guidance outlined in MSIB 02-21 CH-3 remains in effect.

This and other MSIBs are available on the MSIB webpage.
