§  271.  Requirements  for  buildings  erected  before  October first,   nineteen hundred and thirteen.  No  factory  shall  be  conducted  in  a   building  erected  before  October first, nineteen hundred thirteen, and   not occupied or used as a  factory  building  on  July  first,  nineteen   hundred   forty-eight,   unless  such  building  shall  conform  to  the   requirements of  section  two  hundred  seventy.  No  factory  shall  be   conducted  in  a building erected before October first, nineteen hundred   thirteen and occupied or used as  a  factory  building  on  July  first,   nineteen  hundred forty-eight, unless such building shall conform to the   following requirements:1. Required exits. a. On each floor used as a factory there  shall  be   at least two exits remote from each other, except that a single exit may   be  accepted  by  the  commissioner  from  a floor or other area, of one   thousand square feet or less, so long as no person is regularly employed   on such floor or other area. One such exit on each floor shall be either   a grade exit, an interior stairway enclosed as hereinafter  provided  or   ramp similarly enclosed, or an exterior fireproof enclosed stairway. The   other  shall  be:  either  such  a  grade  exit,  stairway or ramp; or a   horizontal  exit;  or  an  exterior  screened   stairway;   or   outside   fire-escapes  on  a  building six stories or less in height, except such   fire-escapes shall not be accepted as a required exit in such  buildings   or  particular  classes thereof where the board finds that they will not   in its opinion furnish adequate and safe means of escape  for  occupants   in  case of fire. Unenclosed exterior stairways or ramps extending up to   grade may be substituted for enclosed stairways from a floor area  below   the ground floor.b. No point on any floor above or below the ground floor shall be more   than one hundred feet distant from the entrance to one such exit at that   floor nor more than one hundred and fifty feet distant from such exit if   the building has an automatic sprinkler system conforming to section two   hundred  and  eighty  and the rules of the board. No point in any ground   floor area shall be more than two hundred feet distant from an exit from   that floor and in a sprinklered building more than two hundred and fifty   feet distant from such exit.c. If safe egress may be had from the roof to  an  adjacent  structure   every  stairway  serving  as a required exit in a building exceeding two   stories in height shall be extended to  the  roof.  All  such  stairways   shall  extend  to  the  first  story  and  lead  to  the street or to an   unobstructed passageway leading to a street or road or to an  open  area   affording safe passage to a street or road.2.  Stairway  enclosures.  All  interior stairways serving as required   exits and the landings, platforms and  passageways  connected  therewith   shall  be enclosed on all sides by partitions of fire-resisting material   extending continuously from the basement to the roof. Where the stairway   continues to the top floor such partitions shall extend  to  three  feet   above  the  roof  or to the roof if it is fireproof. All such partitions   and  doors  provided  for  openings  therein  shall  be  constructed  in   accordance with rules adopted by the board.3.  Doors.  Where  five or more persons are employed on any floor of a   factory building all doors on such floor leading to or  opening  on  any   exit shall open outwardly or be double swinging doors. All exit doors in   the  first  story,  including  the  doors  of  the vestibule, shall open   outwardly.
