From ACCSES:

Please see the Occupational Safety and Health Administration’s Emergency Temporary Standard (ETS) that will apply to healthcare employers and additional OSHA guidance issued to protect workers in workplaces not subject to the ETS.

We had a number of calls asking about the ETS and to what businesses it applies. OSHA prepared this chart to help employers determine if they are subject to the ETS rule. Footnote number 1 is probably the most helpful part of the chart. In addition, the law firm of Troutman Pepper prepared an analysis, which may assist in determining whether your organization is subject to the ETS. We encourage anyone who is unsure whether the ETS applies to their organization to consult with legal counsel.
