The nozzles below the vessel equator are even more crucial than those above as per NFPA 15(2007) Section 7.4.2.4 since the liquid inside is in contact with the bottom of the vessel. Rundown is not considered acceptable to wet this surface and must be directly impinged. Sections 7.4.2.5 and 7.4.2.6 provides additional guidance.

I don't recall any concerns about the wheels. I do remember, when we tested, everything was covered and completely drenched.

I'm concerned about the area beneath the tanker, and especially at the areas shielded by wheels, etc. Wondering if anyone has been involved in a similar installation and if so, how these areas were dealt with.
