I agree. The space directly above the panel, to a height of 6 feet above the top of the panel, can have no pipes. If there are pipes more that 6 feet above the panel, then there must be a drip shield, and even it muse be more than 6 feet above the top of the panel.
You can run the pipes over the working space, as long as they are 6.5 feet over the floor level.
