Based upon our interpretation of the standard, it appears that only the employer's classification of risk exposure would determine when (if ever) the requirements of this standard would no longer apply.  Is the intent to have workers within the same industry or even across industries to act differently (relative to masks, socially distancing, etc.) based upon every employer's interpretation.  It would seem prudent to have an end date of this legislation that could be extended as applicable based upon the state (or county) COVID-19 numbers.  As written, some workers could be in masks forever.  Please clarify.
