From internet writer Carl Herman: Regardless of what the press says, California's governor Gavin Newsom did not issue an Executive Order on June 18th forcing people to wear face masks in public.See for yourself. The California Department of Public Health issued guidanceon June 18, 2020without penalty of law for declining their suggestions/requests.
Normal fresh air contains 20.95% oxygen.OSHA defines an oxygen deficient atmosphere as an “atmosphere with an oxygen content below 19.5% by volume.” (See OSHA: Cloth Face Masks post below to see what happens when you wear a mask.) And, the two-meter (six-foot) rule has no basis in science.
Children are to be sent back to school with masks on. This video documents OSHA's position on certain face coverings and COVID-19, and also explains the what and where of oxygen-deficient environments, e.g., those with too much CO2.
