However, where previously ESFR, CMDA, and CMSA sprinkler schemes were embedded in each of the respective storage chapters, and each chapter was dedicated to a particular type of storage configuration such as rack, palletized, or shelf storage, now a new approach was taken:.
Solid Shelf protection schemes for racks requiring installation of in-rack sprinklers are now separated out in Section If approved, this update will remove this limitation from Table As a result, ESFR sprinklers may be allowed to be installed in these construction types to coincide with the listings allowances in the sprinkler datasheets and FM 2.

Section A. Annex B: Miscellaneous Topics. Section B. Section C. Section D. Section E. Annex F: Informational References. Section F. The purpose of the air venting valve is to exhaust as much trapped air as possible from a single location every time the system is filled.
The objective of venting is to reduce the amount of oxygen trapped in the system that will fuel corrosion and microbial activity. Interconnection of branch line piping for venting purposes is not necessary. System piping layout will guide the designer in choosing an effective location for venting. In order to effectively accomplish venting, it is necessary to choose a location where the greatest volume of trapped air is vented during the first fill and each subsequent drain and fill event.
The vent connection to the system should be located off the top of horizontal piping at a high point in the system; however, the vent connection can also be effectively located off the side of a riser or riser nipple at a high point in the system.
The manual air venting valve should be located at an accessible point and preferably not over 7 ft 2. Automatic air valves are not required to comply with the accessibility requirement of manual air venting valves; however, it is recommended the designer locate automatic air vents over areas without ceilings, above a lay-in ceiling, or above an access panel.
This is one of those items where what is in the standard means little and the annex material is nice but not legally enforceable. Three options are given. What option do you think almost every contractor is going to use?
Think about the following:. The annex material does discuss the accessibility requirement of the valve but none of this language made its way into the standard. Thus it is not enforceable. What does that mean — in the same building, within 10 ft, within 6 ft?
