   (a)   Quantities exceeding five hundred (500) cubic feet of loose combustible fiber shall be stored in fire-resistive storage rooms conforming to the applicable provisions of Section 3129.43(c), having incombustible floor, wall and ceiling construction with a fire resistance rating of not less than two (2) hours. However, when the quantity of combustible fiber stored in such rooms exceeds one thousand (1,000) cubic feet, the required fire resistance rating shall be not less than four (4) hours for walls and partitions and not less than three (3) hours for floor and ceiling construction.

   (b)   All such fire-resistive rooms shall have provisions for venting gas and smoke to the outer air as specified in Section 3129.43(c), except that the required vent area need not exceed one (1) square foot for each two hundred (200) cubic feet of room volume.

   (c)   All interior openings within enclosures of such fire-resistive storage rooms shall have self-closing or automatic opening protectives. Enclosures required to have a fire resistance rating of two (2) hours shall have opening protectives with a fire resistance rating of not less than one and one-half (1-1/2) hours. Enclosures required to have a fire resistance rating greater than two (2) hours shall have openings protected with opening protectives on both sides of the opening. Such opening protectives shall have a combined fire resistance rating of not less than four (4) hours.

§ 385.44 Storage of Baled Fiber in Storage Warehouses or Rooms

   (a)   Blocks or piles of baled fiber stored in storage warehouses or rooms shall be separated from adjacent storage by aisles not less than five (5) feet wide; or by flash fire barriers consisting of continuous sheets of incombustible material extending from the floor to a height of at least one (1) foot above the highest point of the piles and projecting at least one (1) foot beyond the sides of the piles.

   (b)   Sisal and other fibers in bales bound with combustible tie ropes, and jute and other fibers liable to swell when wet, shall be stored to allow for expansion in any direction to the extent of twenty percent (20%) of their bulk without endangering building walls, ceilings or columns. Not less than three (3) feet clearance shall be maintained between sprinkler pipes and the tops of piles. Not less than three (3) feet clearance shall be left between walls and sides of piles. However, when the storage compartment is not more than thirty (30) feet in width, one (1) foot clearance at side walls shall be approved when a center aisle not less than five (5) feet wide is maintained.
