There are a lot of contingencies written into 7.14 that must also be met along with no prohibitions within chapters 11-43 so has all of that been looked at to be sure that sprinklers aren't required by other chapters?
Basically what 101 is describing sounds like a type of concealed space. A.3.3.22.6 Normally Unoccupied Building Service Equipment Support Area. Normally unoccupied building service support areas are often found in attics, crawl spaces, chases, and interstitial areas where the space is vacant or intended exclusively for routing duct-work, cables, conduits, piping, and similar services and is rarely accessed. In such spaces, it is often difficult or impossible to fully comply with the egress requirements of Chapter 7. Where portions of such spaces are routinely visited for storage, maintenance, testing, or inspection, that portion is excluded from this definition, but the remainder of the space might be considered a normally unoccupied building service equipment support area. Storage and fuel-fired equipment would not be expected to be permitted in these locations. Roofs are not considered to be normally unoccupied building service equipment support areas Craig Prahl | Jacobs | Group Lead/SME - Fire Protection | 864.676.5252 | craig.pr...@jacobs.com<mailto:craig.pr...@jacobs.com> | www.jacobs.com<http://www.jacobs.com/> 1041 East Butler Road Greenville, South Carolina 29606 From: Sprinklerforum <sprinklerforum-boun...@lists.firesprinkler.org> On Behalf Of Larrimer, Peter A (HEFP\10NA5B) via Sprinklerforum Sent: Tuesday, June 2, 2020 3:49 PM To: sprinklerforum@lists.firesprinkler.org Cc: Larrimer, Peter A (HEFP\10NA5B) <peter.a.larri...@va.gov> Subject: [EXTERNAL] Exemption for sprinklers NFPA 101, 7.14 (2018) permits sprinklers to be omitted from "Normally Unoccupied Building Service Equipment Support Areas". These support areas are not intended to be accessed by persons for maintenance. However, they might have man-doors installed that would make them accessible and when they are over 45,000 square feet, they are required to have man doors installed. There is a provision in NFPA 101 that states the following: 7.14.2.2 Egress from normally unoccupied building service equipment support areas shall be provided by doors complying with 7.2.1 where the normally unoccupied building service equipment support area exceeds 90,000 ft2 (8370 m2) in buildings protected throughout by an approved, supervised automatic sprinkler system in accordance with 9.7.1.1(1). 7.14.2.3 The absence of sprinklers in the normally unoccupied building service equipment support area, as permitted by an exemption of NFPA 13, shall not cause a building to be classified as nonsprinklered for purposes of applying the provisions of 7.14.2.2. I am looking for the exemption in NFPA 13 that would allow a space to have man-doors, and also allow the sprinklers to be omitted from that space so that I can apply 7.14.2.3. Can anyone help by showing me where that might exist in NFPA 13? This provision was added to the 2012 edition of NFPA 101.
