Greetings to everyone, I have a question:
In my company we have LPG storage spheres, these have their own water spray protection system in case of nearby fire. Now the AHJ says that it is necessary to install fire protection to the above-ground piping located inside of the spheres dikes (this piping carries the fire water to the mentioned sprays), because of the article 12.2.1. from NFPA 24 (2019) which says:
Anyone could help me with this? The AHJ is correct? If that would be the case, what fire equipments would be necessary to protect the fire piping inside of the dikes?
Thank you in advance.
