TVA Procedures require that radiography boundaries shall be marked with yellow and magenta rope, chain or ribbon, signs, and have flashing lights to alert individuals that radiography is in progress. The procedure does not specify the color. Chuck Creamer Charles E. Creamer Health Physicist Tennessee Valley Authority Browns Ferry Nuclear Plant P.O.

If we employ flashing lights for LHRA controls we specify red lights, Palo Verde would like to know: Do you use flashing lights for boundary postings during Radiography? If so, do you specify a particular color of the flashing lights? Seth ********************************************************************** Seth J.
