NFPA 13, 2010 -*The storage of materials in stairwells obstructs the egress route and is prohibited by NFPA 101. However, if there is an open space under the first landing or a large landing at the top of the stairs it is often an irresistible location for transient storage. As a result, 8.15.3.2.1 requires sprinklers at these locations." OK so let's find a new topic for this week. Craig L.

The engineer did not take any license, he only quoted the most recent edition of NFPA 13. The word "accessible" might not be in the 2007 edition, but it does show up in the 2010 edition: "8.15.3.2.1 In noncombustible stair shafts having noncombustible stairs with noncombustible or limited-combustible finishes, sprinklers shall be installed at the top of the shaft and under the first accessible landing above the bottom of the shaft." In fact the word "accessible" is the only difference in the wording of this paragraph between the two editions.
