Which NFPA standard edition addresses wet chemical systems regarding galvanized piping allowances?

• A. NFPA 17A 2017
• B. NFPA 11 2016
• C. NFPA 12 2018
• D. NFPA 750 2019

Answer: (A)

Wet chemical extinguishing systems are specifically governed by the NFPA standard that outlines how these systems are designed, installed, and tested. The 2017 edition of NFPA 17A provides the requirements for the piping materials and how they may be used with the wet chemical agent, including any allowances related to galvanized piping under the standard’s material compatibility and installation rules. This standard is focused on wet chemical systems, whereas the other standards cover foam systems, clean agent systems, or water-mist systems and do not address galvanized piping allowances for wet chemical setups. So, the edition that addresses galvanized piping allowances for wet chemical systems is NFPA 17A from 2017.
