Atlanta ( CNN ) -- Top officials from the Federal Aviation Administration and the air traffic controllers ' union kicked off a cross-country tour of air traffic control facilities on Monday , two days after a seventh reported case this year of a controller falling asleep on the job . FAA Administrator Randy Babbitt and Paul Rinaldi , president of the National Air Traffic Controllers Association , are expected to hold a series of meetings about safety and professionalism . Their first stop was at a radar facility in the Atlanta area . `` None of us in this business can tolerate any of this , '' Babbitt said of the sleeping controllers . `` It absolutely has to stop . ... One mistake is one too many . '' This `` will not be tolerated , '' he insisted . `` We run the safest system in the world , '' but these incidents have `` cast a cloud . '' Inside the life of an air traffic controller . Babbitt described himself as `` infuriated '' after learning about the lapses . `` Any time ( there ) is less than perfection , we have issues , '' Rinaldi added . `` It 's a very big concern , '' Transportation Secretary Ray LaHood said Monday . `` We will do better . '' Federal officials announced a series of new regulations Saturday aimed at preventing air traffic controllers from falling asleep while on duty . Among other things , controllers now must have a minimum of nine hours off between shifts , instead of the current minimum of eight hours . In addition , controllers can no longer be put on an unscheduled midnight shift following a day off . If the shift from eight to nine hours is n't enough , `` then obviously we 'll take that into consideration , '' LaHood said . But it 's up to the controllers `` to take personal responsibility '' and get adequate rest during their down time , he said . FAA managers will also schedule their own shifts in a way to ensure greater coverage in the early morning and late night hours , the secretary noted over the weekend . On Saturday , the FAA suspended an air traffic controller for sleeping on the job at the Miami Air Route Traffic Control Center . According to a preliminary review of air traffic tapes , the controller did not miss any calls from aircraft , and there was no operational impact , the agency said in a statement . The incident was reported to a manager by another controller , the FAA said . There were 12 controllers and two managers on duty at the time . Last week , the head of the FAA Air Traffic Organization , Hank Krakowski , resigned over the uproar caused by the recent spate of incidents . David Grizzle , the FAA 's chief counsel , has been named acting chief of the unit . Will NextGen air traffic overhaul make us safer ? Aside from Miami , cases of sleeping controllers have been reported in Washington ; Knoxville , Tennessee ; Seattle and Reno , Nevada . There have been two suspected cases in Lubbock , Texas . All of the incidents occurred during controllers ' midnight shifts . Most of the lapses occurred at local control towers . In at least one incident , the FAA has said , the controller deliberately went to sleep , while some of the others appear to have been accidental .
