OSHA updated its masking guidance for fully vaccinated workers. It recommends they wear masks in public indoor settings in areas of substantial or high transmission, such as factory workers. It also recommends masking, regardless of the level of transmission, for “at risk” individuals. And it suggests testing 3-5 days following a known exposure to someone with suspected or confirmed COVID-19 and wearing a mask in public indoor settings for 14 days after exposure or until a negative test result. #IdeaoftheDay
