Editing 2367: Masks

*'''{{w|scuba set|SCUBA}}''': A '''S'''elf-'''C'''ontained '''U'''nderwater '''B'''reathing '''A'''pparatus. Most SCUBA equipment used an open-circuit design allowing exhaled air to vent to the atmosphere. Underwater, this would not be a threat to other divers who would also be breathing air from their tanks. However, on land a typical SCUBA regulator would expose others to virus particles. Closed-circuit SCUBA equipment recirculates the user’s gas supply but they still contain a means of venting extra gas into the atmosphere. Neither system contains expiratory HEPA filters making both ineffective at preventing virus transmission. That all said, SCUBA equipment still covers the face and nose, rather than directly exposing others to unshielded breathing and coughing.

*'''{{w|Darth Vader|Vader}}''': Reference to one of the main antagonists in {{w|''Star Wars''}}, in which he wears a suit of armor with a built-in rebreather. Similar to SCUBA gear, it circulates air back to the user, in order to defend against the spread of the virus to the wearer.  The question of whether Vader's mask would protect against COVID was implicitly referenced again in [[2441: IMDb Vaccines]].

*'''Haunted Halloween Masks''': The title text is a reference to ''{{w|The Haunted Mask}}'' by {{w|R. L. Stine}}, a book in the {{w|Goosebumps (original series)|''Goosebumps'' series}}.  The mask transforms the wearer into a monster, with an open (uncovered) nose and mouth. The test results claim that the wearer is still somehow substantially protected against inhaling virus particles, but this may be a fraudulent test result due to pressure from the sponsor of the test, R. L. Stine, to get more people to wear such masks; it is also possible that the supernatural effects somehow include blocking virus particles, as parasites generally benefit from keeping their hosts alive and healthy, at least in the short term. NIOSH refers to the ''{{w|National Institute for Occupational Safety and Health}}''.
