Jim, contact APA help desk (tel. 253-620-7400) for APA handout on this subject. Before the job starts, it would be a good idea to check with contractor to make sure that pneumatic fastening equipment has adjustable depth feature to control driving of nails or staples so the head or crown is flush with the surface of the sheathing. Existing tools can be modified by service reps; and new tools have depth control feature. Controlling depth of driving fasteners by adjusting air pressure doesn't work.
