Air Vents and Freeze Protection in Fire Sprinkler Systems: New Requirements of 2016 NFPA 13
February 10, 2021
Jurisdictions are adopting the International Building Code 2018 edition and the 2018 edition of NFPA 101: Life Safety Code that adopt the 2016 edition if NFPA 13 by reference. This program will address technical changes specific to corrosion and air vents for the 2016 edition of NFPA 13. The 2016 NFPA adds a new requirement that a single air vent be installed for each wet sprinkler system to help reduce potential corrosion activity due to trapped air. A task group concluded that venting the trapped air in a wet system can decrease water delivery time, reduce alarm ring delay, reduce water flow alarm cyclic ringing, and reduce corrosion activity. Additionally, a brief review of code requirements pertaining to auxiliary drains on dry and preaction systems. Participants will understand the intent of the new code, design requirements and current air vent and auxiliary drains on the market.
