A. Before personnel begin maintenance activities on components handling flammable fluids which are isolated for maintenance, the component must be purged in accordance with a procedure which meets the requirements of "Purging Principles and Practices (incorporated by reference, see LAC 43:XIII.6713)"; unless the maintenance procedures under LAC 43:XIII.7905 provide that the activity can be safely performed without purging.
