President Obama has ordered federal buildings to fly the flag at half-staff Sunday, Oct. 9, which is National Fallen Firefighters Memorial Service Day.
The president issued the proclamation Oct. 7.
USPS facilities that fly the flag at all times and are closed Sunday should lower the flag to half-staff when the facility closes prior to National Fallen Firefighters Memorial Service Day. Return the flag to full staff when the facility next opens for business.
To fly the flag at half-staff, hoist the flag to the peak for an instant and then lower it to the half-staff position. The flag should be raised to the peak again before it’s lowered for the day.
The Postal Service’s guidelines on U.S. flag display and maintenance have additional information.
