or rope fire-escapes shall not be accepted as a required or alternative

and replaced by a system of fire-escapes constructed and arranged as
provided in section one hundred thirty-three. All fire-escapes erected
on or after July first, nineteen hundred fifty-three, to serve as a
second means of egress shall be in conformity with the provisions of
