§  272. Additional requirements for all buildings. No factory shall be   conducted in any building unless such building shall be so  constructed,   equipped and maintained in all respects as to afford adequate protection   against  fire to all persons employed therein, nor unless in addition to   the provisions of sections two hundred and seventy and two  hundred  and   seventy-one such buildings shall conform to the following requirements:1.  Access to exits. Every exit shall be maintained in an unobstructed   condition. Safe and continuous passageways with an unobstructed width of   at least three feet throughout their  length  and  leading  directly  to   every  exit  including  fire  escapes  and  passenger elevators shall be   maintained at all times on every floor of the building.2. Stairways. Stairways shall be  provided  with  proper  hand  rails.   Where the stairway is enclosed by fireproof partitions the bottom of the   enclosure  shall  be  of  fireproof material at least four inches thick,   unless such partitions extend to the cellar bottom. If safe  egress  may   be  had  from the roof to an adjacent structure all stairways serving as   required exits and extending to the top story shall be continued to  the   roof.3.  Doors  and  windows. No door leading into or out of any factory or   any floor thereof shall be locked, bolted  or  fastened  during  working   hours.  No  door on any floor shall be obstructed by metal bars, grating   or wire mesh. Metal bars, grating or wire mesh provided for  any  window   or  other  opening  shall  be so constructed as to be readily movable or   removable from the inside so as to  afford  free  and  unobstructed  use   thereof  as  a  means  of  egress and they shall be left unlocked during   working hours. Every door opening on a stairway or other exit shall open   from both sides so as not to obstruct passage. Doors opening directly to   the street or to yard or open area, may be provided with panic bolts  of   an approved type.4.  Exit signs. An exit sign shall be placed over all openings leading   to stairways and other exits. Such sign shall be legible and visible  in   accordance  with  rules,  regulations or requirements established by the   State of New York Board of Standards and Appeals.5. Vertical openings. All vertical openings leading from one floor  to   another,  except  one created by a mezzanine floor, shall be enclosed by   fire-proof or  fire-resistive  materials  and  ventilated  in  a  manner   conforming to rules adopted by the board.6.  Floors.  Floors  in  buildings  more  than  one and less than five   stories in height erected after October first, nineteen hundred thirteen   and in all buildings erected prior thereto shall be  so  constructed  or   provided with a protective ceiling as to have a fire-resistive rating of   at  least  one  hour.  This  subdivision  shall  not apply where factory   buildings are provided throughout with an automatic  fire  extinguishing   system approved in the city of New York by the fire commissioner in such   city and elsewhere by the commissioner.7.  Regulations  by  board.  The  board  may adopt rules and establish   requirements and standards for construction, equipment  and  maintenance   of  factory buildings or of particular classes thereof and the means and   adequacy of exit therefrom in order to carry out the  purposes  of  this   chapter, alternative or in addition to the requirements of this article,   and not inconsistent with the spirit thereof.
