Must contractor employees wear the mask at all times they are within the Port offices?

Yes. Contractor employees within open areas or cubicles must wear their masks at all times in the office area.  If an individual worker is alone in a fully enclosed office or meeting room and no one else is in the office or meeting room, then the individual may remove the mask while in there.  The individual must put the mask back on if someone opens the door and/or enters the office or meeting room. Contractor employees are permitted to very briefly remove their masks in Port offices as may be required by necessity for hygiene or other very brief reasons (e.g., to blow one’s nose in a bathroom or to take a drink, etc.).
