Master Sgt. Henry Matsuoka, section chief, air crew flight equipment, 412th Operations Support Squadron, 412th Operations Group, 412th Test Wing, demonstrates proper use of a mask that was fabricated using available equipment in the Air Crew Flight Equipment section at Edwards Air Force Base, April 7. Although cloth masks don’t offer full protection from COVID-19, the CDC advises that a simple cloth covering can slow the spread of the virus and help people who may have the virus and not know it from spreading it to others.
