DEFINITION OF TERMINOLOGYEXPLANATION OF COLUMN HEADINGS:

SAFETY: ITEM JUDGED TO HAVE A SAFETY DEFICIENCY REQUIRING IMMEDIATE ATTENTION. FAILURE TO REPAIR THIS DEFICIENCY MAY RESULT IN PHYSICAL HARM TO PERSONNEL ON THE TOWER AND GROUND.

EMERGENCY: ITEM JUDGED TO HAVE A DEFICIENCY REQUIRING IMMEDIATE ATTENTION. FAILURE TO REPAIR THIS DEFICIENCY MAY RESULT IN TOWER FAILURE, PROPERTY DAMAGE, OR INJURY TO PERSONNEL ON TOWER AND GROUND.

OFF AIR: ITEM JUDGED TO HAVE A DEFICIENCY REQUIRING IMMEDIATE ATTENTION. FAILURE TO REPAIR THIS DEFICIENCY MAY RESULT IN LOSS OF AIRTIME.

ROUTINE: ITEM JUDGED TO HAVE A DEFICIENCY REQUIRING IMMEDIATE ATTENTION. FAILURE TO REPAIR THIS DEFICIENCY MAY ESCALATE INTO A SAFETY, EMERGENCY, OR OFF AIR CONDITION.

THE CRITERIA USED IN MAKING OUR RECOMMENDATIONS AND OBSERVATIONS ARE BASED ON THE FOUR LEVELS OF PRIORITY:

FIRST: "KEEP THE TOWER STANDING". THESE ARE STRUCTURAL INTEGRITY ITEMS THAT AFFECT THE STABILITY OF THE TOWER.

SECOND: "AVOID OFF AIR AND/OR DOWN TIME". THESE ARE SYSTEM INTEGRITY ITEMS, WHICH CAN AFFECT THE SIGNAL OR ABILITY TO REMAIN ON AIR.

THIRD: "AVOID LIABILITY RISK". THESE ARE LIABILITY ITEMS SUCH AS HAZARDS TO CLIMBERS OR PERSONS AT OR AROUND THE STRUCTURE, INCLUDING "ATTRACTIVE NUISANCE" POTENTIALS.

FOURTH: "KEEP THE COST OF OWNERSHIP AS LOW AS PRACTICAL". THROUGH CAREFUL MAINTENANCE AND PREVENTATIVE MAINTENANCE, THE UTILITY VALUE OF THE STRUCTURE CAN BE MAXIMIZED AND THE COST KEPT LOW.

Min. Torque (Ft-Lbs):

EXPLANATION OF BOLT TORQUE CHECK STRUCTURAL BOLT CONNECTIONS ARE "SAMPLED" AT THE RATE OF AT LEAST 10 BOLTS PER EACH 20 VERTICAL FEET OF TOWER HEIGHT. THE TOWER IS CONSIDERED TO BE IN ACCEPTABLE CONDITION IF THE NUMBER OF UNDER-TORQUED BOLTS IS FOUND TO BE NO MORE THAN 5% OF THE TOTAL SAMPLED.

THE TOWER IS SAID TO HAVE A "MAINTENANCE DEFICIENCY" IF THE NUMBER OF UNDER-TORQUED BOLTS IS 6% TO 30% OF THE TOTAL SAMPLED. IF THIS IS THE CASE, THE TOWER SHOULD BE RE-CHECKED, AT LEAST ANNUALLY. SINCE EACH UNDER-TORQUED BOLT FOUND DURING THE RANDOM SAMPLING PROCESS IS RE-TIGHTENED TO THE PROPER LEVEL, THE NUMBER OF UNDER-TORQUED BOLTS WILL EVENTUALLY DROP BACK BELOW THE STRUCTURALLY UNACCEPTABLE CONDITION AND ALL BOLTS SHOULD BE CHECKED AND RE-TIGHTENED TO CORRECT LEVELS.
