  (3) At least one hand-washing facility shall be located in or adjacent to any toilet room provided for employees' use, whether these are portable or at fixed (permanent) locations. A minimum of one hand-washing facility shall be provided for each two toilet facilities, as determined from the requirements of §295.166(a)(3) of this title (relating to Standards for Toilet Facilities and Toilet Rooms).
  (4) A dispenser containing a suitable cleansing agent shall be provided for each hand-washing facility. Individual hand towels and proper receptacles for their disposal shall be located conveniently.

This alternative shall not be employed as a permanent substitute for hand-washing facilities, however.
