Narrative

WE CLOSE FLORENCE APCH AT XA00 LCL. THE JANITOR WENT INTO THE EQUIP ROOM AND BROUGHT IT TO OUR ATTN THAT IT WAS VERY HOT IN THERE. WE FOLLOWED PROCS BY CALLING CAE (COLUMBIA) GMCC (GNAS MAINT CTL CTR); THE MAINT TECHNICIAN WANTED US TO CHK THE CIRCUIT BREAKERS. EVERYTHING LOOKED ALL RIGHT. THE TECHNICIAN SAID HE NEEDED TO THINK ABOUT CALLING SOMEBODY OUT. WE OPENED THE DOORS TO THE EQUIP ROOM TRYING TO KEEP IT COOL AND LEFT AT XA00. THE NEXT MORNING THE COMMERCIAL PHONES WERE RINGING NONSTOP. OUR OWN AF TECHNICIANS SHOWED UP AT THEIR USUAL XJ00 START TIME. THEY SHOWED US A BACKUP AIR- CONDITIONING SWITCH THAT WAS NOT LABELED VERY WELL AND APPARENTLY THE GMCC TECHNICIAN WAS NOT EVEN AWARE OF. I FEEL THAT AIRWAYS FACILITIES (AF) IS SO WORRIED ABOUT SAVING MONEY THAT THEY WOULD NOT SEND ANYBODY OUT. THIS COULD HAVE BEEN DISASTROUS BY FRYING NOT ONLY THE COMMERCIAL PHONES LINES BUT ALL THE OTHER EQUIP (IE; ARTS; LAND LINES; IDS). I ALSO THINK THERE NEEDS TO BE AN ALARM OR AT LEAST AN AUTOMATIC SWITCH TO THE BACKUP AIR- CONDITIONING. WHAT IF IT HAD HAPPENED AFTER WE HAD LEFT? CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT BEARINGS IN THE AIR-CONDITIONING UNIT WERE REPLACED. RPTR SAID THERE IS NO AUTOMATIC SWITCHING TO THE BACKUP AIR-CONDITIONING. RPTR INDICATED THAT SOME OF THE EQUIP HAS BUILT IN HEAT ALARMS WHICH WERE NOT HEARD IN THE CTL ROOM. RPTR IS UNAWARE OF ANY DISCUSSION REGARDING HAVING A TECHNICIAN CALLED OUT IN THE EVENT OF AN OVERHEAT PROB OR HOW TO HANDLE THE PROB WHEN THE FACILITY IS CLOSED.
