I have been wearing my fingers to the bone googling this. I will be placing some equipment in a C1D2 location. The location is an aircraft manufacturing facility. The aircraft in this facility has been previously fueled and drained but not purged. Therefore this facility falls under NEC 513. The problem I am having is determining the Group (A, B, C, D) of the Jet A-1 fuel that will be present in small quantities on the aircraft being serviced in this hangar.
Any help is greatly appreciated.
