This will vary from airport to airport and depends on airline policy. AIP charts usually go out to a distance of approximately 72,000 feet.
Try insisting that your performance engineers issue an engine failure procedure which finishes at a fixed point, i.e. At 3 miles, right turn back to the VOR and hold. At least this way you know that you will clear all the terrain beneath you.
BTW, the 72,000 feet clearance also applies on straight out departures.
