Nice for e heli-deck but not much use for an asphalt or concrete pad which requires UL/FM listings/approvals.
This is not a difficult installation. Locate spray nozzles low alongside the loading/unloading area, positioned to spray below the tanker and truck. They are either mounted to canopy structural members or pipe stands. It's done this way for over-the-road tankers and rail cars. Viking had some great info on their nozzles which would show projection distance based on inlet pressures and spray angles. You've got to have enough pressure to penetrate and reach below the trailer. It's not super difficult nor expensive like specialty pop-up thingy nozzles. Craig L.

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.
