,The failure to issue the proper torque conversion chart as-required by Mechanical Maintenance Procedure)(MMP) 285.003,
" Calibration of - Torque Wrenches Preventative Maintenance," was
.due to personnel' error.
At the time, predetermined torque-conversion data. sheets were allowed to be issued for field use Land ~the lab attendants issued ~an incorrect. data sheet for the specific wrench /crowsfoot/ angle combination.
A second_ violation, which was caused by personnel error, was
-identified in that a degraded fire barrier was not promptly reported as' required by. Station Administrative Procedure (SAP)

CORRECTIVE ACTION TAKEN TO AVOID FURTHER VIOLATION It is now required that a torque conversion chart be prepared
.to correlate the torque output to the input indicated on the torque' wrench.for the specific wrench /crowsfoot/ angle combination at the time of issuance.
The use of predetermined developed torque data sheets which reflect the exact combination has been discontinued.
A procedure change deleting the'use of predetermined developed torque data sheets will be implemented by April 30, 1985.
