Persons aboard commercial vessels or at sea ports are still required to wear masks, USCG confirms
In a reminder that we are still managing a global pandemic, the U.S. Coast Guard (USCG) confirmed that MSIB 02-21 CH-1 issued on March 22, 2021 requiring masks be worn aboard commercial vessels and at seaports to mitigate the risk of spreading COVID-19 is still the latest and controlling guidance on the topic.
According to the Centers for Disease Control and Prevention (CDC), there is no change to the requirements issued in EO-13998 by the President of the United States on 21 January 2021 and in the CDC Federal Order, signed 29 January 2021 and issued pursuant to Section 361 of the Public Health Service Act, requiring all persons traveling on all commercial vessels to wear a mask.
Additionally, the USCG was ordered to implement public health measures consistent with CDC guidelines at all seaports. The USCG did so in MSIB 02-21 CH-1, a copy of which can be found in the side bar.
