James Warren, 436th Operational Medical Readiness Squadron bioenvironmental engineering flight noncommissioned officer in charge, tests non-potable water for pH and chlorine levels March 18, 2020, at the main gate on Dover Air Force Base, Delaware.

After applying hand sanitizer during the screening of medical clinic patrons, 436th OMRS personnel were required to wash their hands after the fifth screening before reapplying more hand sanitizer.
