'Airport workers keep our regions supply chain moving and support safe essential travel,' said Port of Seattle executive director Steve Metruck.
'I am deeply grateful for the dedication they bring to their work. Many port employees and partners and members of the public already wear cloth face coverings. This policy makes clear our commitment to public health, safety, and well-being.' Mr Metruck said.
As part of its response to the global coronavirus pandemic, the port began providing cloth face coverings to staff working in public facing roles on April 17 and encouraged employees to follow the US Centres for Disease Control and Prevention (CDC) guidance to wear cloth face coverings in situations where it is difficult to maintain physical distancing.
Many partners across port facilities already recommend or require face coverings for employees and passengers as an added safety measure this includes airlines, retail and dining tenants, and government agencies including Transportation Security Administration (TSA), and CDC, and Customs and Border Protection (CBP).
