Jurisdictions are adopting the International Building Code 2018 edition and the 2018 edition of NFPA 101: Life Safety Code that include the 2016 edition if NFPA 13 by reference, and some are even adopting the 2019 edition of NFPA 13. This program will address technical changes specific to corrosion and air vents for the 2016 and 2019 editions 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, and this requirement stays in the 2019 edition. 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. Participants will understand the intent of the new code, design requirements and current air vent options on the market. This program should appeal to sprinkler designers, installers, estimators, and engineers, fire code officials, AHJs, and plan reviewers.
