Inspection found that none of the fire handles had been pulled, boost pumps for the main wing tanks and fuel shut off valves were still on. The "fire" and "failure" checklists were identical, with the addition of cancelling the fire bell and pulling the fire handle in the fire case. Confusion stemmed from "failure" being called first and then changed to "fire" at the same time as the Check Captain making the suggestion to call a mayday.
