Bobby: In a pinch, FM and NFPA typically recommends 0.3 gpm / ft sq. A.S. over many combustible liquids. Since it is confined to a small pit, I would be *more than comfortable *with this application rate of water-only agent. This applicaton will not put our fire out, but it will keep things cool till foam or dry-chem puts the kabosh on it.
Be sure to interface with the GC about drainage. If none, fine. If there is drainage, have a P-trap in the drain so fire doesn't pass down and continue the same.
