Description
NFPA 13, Standard for the Installation of Sprinkler Systems, 2022 edition
NFPA 13 is the standard automatic sprinkler systems are designed, installed and acceptance tested against. Engineers, contractors and inspectors all work from it, and the 2022 edition is the version most jurisdictions and specifications now point to.
Much of what changed in this cycle comes from storage protection, where the research has moved fastest.
Chapter 26 and single row rack storage
The new Chapter 26 sets out protection schemes for single row rack storage of Group A plastics, including racks with solid shelves. In many arrangements it removes the need for redundant in rack sprinklers, which gives designers more room to work.
ESFR placement and obstructions
The rules for Early Suppression Fast Response sprinklers near obstructions have been clarified, and the obstruction rules generally have been consolidated so that compliance is easier to demonstrate.
Nitrogen generators and dry pipe systems
Where a nitrogen generator is used, the 2022 edition grants exemptions from certain air venting requirements in dry pipe systems. The point is corrosion: less oxygen in the pipe means less of it.
What else changed in 2022
- New protection criteria for single row racks with solid shelves.
- Clarified ESFR sprinkler placement around obstructions.
- Air vent exemptions in dry pipe systems using nitrogen generators.
- Consolidated obstruction rules.
- Updated allowances for automated testing and remote monitoring of system components.
