Regarding the Blasting and Coating activities, all welded areas and appurtenances should be given special attention for removal of welding flux in crevices. Welding splatter, slivers and underlying mill scale exposed during blasting should be removed or repaired. Before any primer is applied, all areas should be checked and all welding and cleaning pickups completed.
After blasting, all blast grit and dust should be cleaned from both internal and external surfaces, including removal from crevices, recesses, etc. All exposed laminations on structural items, shapes, girder beams, etc., should be grounded smooth and surface treated before the primer is applied. Any areas of lamination requiring NDE should be checked, remedial repairs made, re-blasted and re-primed.
