Corrosion and Air Vents: NFPA 13 Code Requirements
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 code requirement that a single air vent is 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 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 vents and corrosion monitors offered in the market. This program should appeal to sprinkler designers, installers, estimators, engineers, fire code officials, AHJs and plan reviewers.
- Recognize the intent of the new code change pertaining to air vents and corrosion in NFPA 13 2016 and 2019 editions;
- Define what is considered a system, and the number of air vents required by code;
- Identify the ideal placement of air vents in wet sprinkler systems and why inspectors' test valves are not ideal air vents; and
- Comprehension of products available in the market today, including air vents, corrosion monitors and their features.
