Why Todd, I am so glad you asked..... The task group knew that we would need to differentiate between concealed and non-concealed spaces in way that 8.15 just doesn't do. Step one? Define Concealed... Here is our task group's best effort (and it pulls from other NFPA definitions as suggested earlier): 3.3.6 Concealed Spaces 3.3.6.1* Concealed Space. An area of or space within a building that is not accessible for storage purposes and is not normally occupied by people but could be entered occasionally for brief periods. The space shall be considered a concealed space even with small openings as defined in 3.3.6.2. A.3.3.6.1 The concealed space most commonly referred to in this context is the space above a ceiling. This definition should not be limited to these spaces. Concealed spaces can be found inside buildings between rooms and between ceilings and floors. They can also be found outside buildings in eaves and overhangs.
We will see if this makes it through the ROC, because the Committee said they LOVED our work but couldn't accept it without real world fire tests behind it. So we will be back in October with more data. And for Ron, we did NOT talk about sloped ceilings just yet. Although the Academy students drew a "sloped acoustical panel" arrangement like the one Steve Leyton had referred. It should be recognized that the above is my opinion as a member of the NFPA, and has not been processed as a formal interpretation in accordance with the NFPA Regulations Governing Committee Projects and should therefore not be considered, nor relied upon, as the official position of the the NFPA, nor any of their technical committees.
