  ninety-five  shall  apply  to   wash-rooms,   washing   facilities   and
  waterclosets  for  employees  mentioned  in  this section; and where the

  eighty-one shall apply to washrooms, washing facilities and waterclosets
  for employees engaged in the care, custody or operation of  an  elevator
  in  such  building or place. For the purpose of so applying the sections
  last referred to, the term "mercantile establishment"  as  therein  used
  shall  be deemed to mean and include a building in which the elevator is
  located or with which it connects.
