In case you needed a copy, the City of Miami revised their original order to require workers on construction sites to wear a face mask at all times, as of 11:59pm April 8, 2020. Workers should refrain from wearing N95 respirators unless required by OSHA regulations, reserving the N95 respirators for health care providers and first responders. In this order, a mask is any covering of the nose and mouth that includes a face mask, scarf, bandana, handkerchief or other cloth coverings.
