DoD Guidance for Masks and Compliance with CDC Guidelines


The Department of Defense (DoD) has released a memorandum that builds on the guidance from Executive Order 13991 and the Center for Disease Control (CDC) on the “Use of Masks and Other Public Health Measures.”  The memorandum reinforces the wearing of face masks on all military installations, in common areas and outdoor shared spaces in accordance with CDC guidelines. Additionally, the memorandum identifies the following exceptions where a face mask is not required.


Individuals must wear masks continuously while on military installations except:

  • When an individual is alone in an office with floor-to-ceiling walls with a closed door 
  • For brief periods of time when eating and drinking while maintaining distancing in accordance with CDC guidelines 
  • When the mask is required to be lowered briefly for identification or security purposes
  • When necessary to reasonably accommodate an individual with a disability 


Face masks must be worn in common areas or shared workspaces (including open floorplan office spaces, cubicle embankments, and conference rooms) and in outdoor shared spaces. 

  • Masks must cover both the nose and mouth
  • Masks with ventilation holes and face shields are not authorized
  • Following CDC guidelines such as social distancing and frequent hand washing continues to be required
