The nine men who are qualified to test the discs are: Riggans Goodwin Thompson Blanchard Edwards Frye McAllister Two men are required to remove 8 install discs. One of these men will be from the list of nine above. WITNESSES All supervisors and engineers on mechanical weekend call are qualified witnesses. After mechanics have been called in, the guard should then contact the individual who had weekend duty last for the mechanical department. As an example; if a witness was required on 8/18/83, then the individual responsible for weekend duty on 8/13 and 8/14-should be contacted. If this person is not available, the individual scheduled for duty the previous week (8/6 and 8/7) will be called. This will continue until a witness is contacted. lpc cc: JLH, CED, JAD, CRM, PEM, AHS DTH 000069566
