#257 Material Storage

(a) Piles of brick, tile, masonry blocks, & similar material shall be stabilized against falling by use of headers at least every 6th course. When a loose brick stack reaches a height of 4 ft, it shall be tapered back at least 2 inches in every foot of height above 4-ft level. Brick stacks shall not be more than 7 ft in height. When masonry blocks are stacked higher than 6 ft, the stack shall be tapered back one-½ block per tier above the 6-ft level.
(b) In piling bags of cement or other material more than 5 ft high, the face of the pile shall be tapered back (except where supported by walls or otherwise), or the sacks shall be so tied in horizontal layers as to prevent them from falling or collapsing.

(c) Piles of lumber, structural steel, and similar materials shall be maintained so that the stack is stable against falling or collapsing. Headers, crosspieces, or other means shall be used as needed in the pile to prevent slipping, tipping, or collapsing. Lumber piles shall not exceed 20 ft in height provided that lumber to be handled manually shall not be stacked more than 16 ft high.

(d) Sheetrock, plywood, trusses, and similar material shall not be stacked on edge unless positively secured against tipping or falling.

(e) Material inside buildings under construction shall not be placed within 6 ft of any hoistway or inside floor openings, nor within 10 ft of an exterior wall which does not extend above the top of the material unless the material is positively barricaded, placed, or secured to prevent it from falling.

(f) The maximum safe load limits of floors, or portions of floors, used for storage areas within buildings and structures, shall not be exceeded.

(g) Materials which may cause a hazardous reaction or unstable condition while in storage shall be segregated.

(h) Material on balconies or in other similar elevated locations on the exteriors of buildings under construction shall be placed, secured or positively barricaded in order to prevent the material from falling.
