§  233.  Bulkheads  and scuttles. 1. Every tenement, except as in this  section otherwise provided, shall have in the roof a fireproof  bulkhead  with  a  fireproof  door  and  after  January  first,  nineteen  hundred  fifty-seven, the door shall be self-closing. Bulkheads existing on April  eighteenth, nineteen hundred twenty-nine, shall be  lawful  and  may  be  replaced  or  repaired with material conforming to the material of which  such bulkhead consisted on such date.    2. A bulkhead in the roof of an old-law tenement which is more than  a  basement  and  four  other  stories in height or which is a basement and  four other stories in height and occupied by three or more  families  on  any  story,  may  be  of  wood  covered  with  metal  on the outside and  fire-retarded on the inside. Such a bulkhead shall be  equipped  with  a  fire-retarded door and assembly with the door self-closing.    3.  In any old-law tenement which is four stories or less in height or  which is a basement and four other stories in height and occupied by not  more than two families on any  story,  no  bulkhead  shall  be  required  provided such tenement is equipped with a scuttle located in the ceiling  of  a  public  hall  on  the  top  story and with access thereto direct,  uninterrupted and easily accessible to all tenants.  All  such  scuttles  shall  be at least twenty-one inches in width and twenty-eight inches in  length. They shall be constructed so as to be readily opened, covered on  the outside with metal and  provided  with  stairs  or  stationary  iron  ladders leading thereto.    4.  Every  required  stair  in  every  tenement  erected  after  April  eighteenth, nineteen hundred twelve, which is more than a  basement  and  three  other stories in height shall extend to and through a bulkhead in  the roof. Such bulkhead shall have a fireproof door  and  assembly  with  the  door self-closing and may be constructed of wood covered with metal  on the outside and fire-retarded on the inside.    5. Stairs  leading  to  required  bulkheads  shall  be  fireproof  and  constructed  as  specified  in  sections  two hundred thirty-four to two  hundred thirty-eight inclusive, except that any such stairs existing  on  April  eighteenth,  nineteen  hundred  twenty-nine,  shall  be permitted  without alteration, and that any such stairs constructed after such date  in any old-law tenement may have such width and  angle  of  ascent,  and  risers  and  treads  of  such dimensions, as approved by the department.  All stairs to required bulkheads shall be provided with a guide or  hand  rail.    6. Bulkhead doors and scuttles shall not be self-locking, and shall be  fastened  on  the inside with movable bolts, hooks, or a lock which does  not require a key to open it from the inside of the  dwelling.  All  key  locks are unlawful and where existing shall be removed.
