Each level has clear verification points, judgment criteria, and handling methods for non-compliance, ensuring the records are accurate, complete, and auditable.<br \/>\n1. Level 1 Review: Operator Self-Inspection (Immediate execution upon completion, the first checkpoint)<br \/>\nVerification steps and verification contents<br \/>\nVerification of basic information completeness<br \/>\nCheck if all items such as equipment number, date, shift, start-up and shutdown time, and operator signature are filled in, with no blank spaces; if the equipment is idle on the same day, note &#8220;This shift did not use the equipment, it is in standby mode&#8221;.<br \/>\nSelf-check of quantitative parameters authenticity<br \/>\nObserve the differential pressure gauge and wind speed display again: Check if the negative pressure and wind speed values in the record table are consistent with the current reading of the instrument; if the values exceed the standard range (\uff1c-15Pa or \uff1e-30Pa, wind speed \uff1c0.35\/\uff1e0.45m\/s), it must be noted in the abnormal column, and &#8220;normal&#8221; cannot be only checked.<br \/>\nItem-by-item verification of qualitative items<br \/>\nVerify each item one by one, confirm that each row is checked; if &#8220;abnormal&#8221; is checked, it must be accompanied by a textual description, and cannot only mark the abnormal without description.<br \/>\nCompliance check of modification traces<br \/>\nIf there is incorrect data, confirm that it is corrected by double-line drawing, write the correct value above, and sign the name at the modification place, without correction liquid or blackening coverage.<br \/>\nSelf-check of abnormal closed loop<br \/>\nIn case of equipment failure or parameter over-limit, confirm that the handling actions have been clearly stated (clean the filter screen\/close the door and tighten\/report for maintenance\/shut down), and remeasure the data after handling.<br \/>\nClosing column confirmation<br \/>\nThere should be no blank spaces in the end-of-shift summary and handover remarks\uff0c and if there are no abnormalities\uff0c write &#8220;No abnormalities&#8221; by hand and sign personally.<br \/>\nDisposal of self-inspection non-compliance<br \/>\nCorrect and complete on the spot\uff0c and submit to the team leader for review after all checks are correct.<br \/>\n2. Level 2 Review\uff1a On-duty team leader review (On-site verification before the end of each shift in the negative pressure weighing room\uff0c core checkpoint)<br \/>\nIt is necessary to bring the paper record table to the negative pressure weighing room for on-site comparison. It is prohibited to only review on the paper surface in the office.<br \/>\n1. On-site physical comparison verification (core\uff0c prevent false records)<br \/>\n1) Verify negative pressure parameters<br \/>\nRead the real-time value of the differential pressure gauge on site and compare it with the filled values in the record table. If the error is too large (over \u00b13Pa)\uff0c it is determined that the record is distorted\uff0c and it is returned for re-measurement and re-filling.<br \/>\n2) Verify the wind speed at the operation port<br \/>\nMeasure the actual wind speed of the fan and compare it with the recorded wind speed\uff1b only check &#8220;normal&#8221; and do not fill in specific values directly\uff0c it is determined that the record is incomplete.<br \/>\n3) Visual verification of each item of equipment status<br \/>\nCheck if the sealing of the door gasket\uff0c gloves\uff0c fan\uff0c return air filter\uff0c filter\uff0c alarm\uff0c and lighting are damaged and leaking\uff0c and whether they are consistent with the description in the record\uff1b<br \/>\nCheck if the dust accumulation of the return air port and filter screen is consistent with the description in the record table\uff1b<br \/>\nVerify the sound and light alarm function\uff0c and check the description in the record\uff1b check if the fan has abnormal noise and vibration\uff0c and confirm it with the on-site record.<br \/>\n2. Paper surface completeness verification<br \/>\n1) No blank spaces\uff1a All inspection rows\uff0c signature columns\uff0c and abnormal description columns must not be left blank\uff1b<br \/>\n2) Abnormal closed loop verification\uff1a When there are records of exceeding standards or damage\uff0c verify if the handling measures and re-measurement results are recorded\uff1b only a description of the abnormality without a disposal record is determined as unqualified\uff1b<br \/>\n3) Complete signatures\uff1a The operator has signed\uff0c and the team leader completes the review and signs their own name and time\uff1b<br \/>\n4) Logical consistency verification\uff1a<br \/>\nExample\uff1a The record states &#8220;Medium-efficiency filter is severely dusty&#8221;\uff0c but there is no reporting for maintenance or replacement remarks\uff0c it is determined that the logic is contradictory\uff0c and it is required to supplement the explanation.<br \/>\n3. Classification and disposal of review results<br \/>\nQualified\uff1a Team leader signs for confirmation\uff0c and the record table is uniformly retrieved and archived\uff1b<br \/>\nMinor defects (omission of remarks\uff0c unclear handwriting\uff0c brief abnormal description)\uff1a Immediately return to the operator for supplementation and improvement before re-review\uff1b<br \/>\nSerious defects (data fraud\uff0c pre-filled\uff0c proxy-filled\uff0c concealing equipment abnormalities\uff0c a large number of blank items)\uff1a The record table is invalidated\uff0c the on-site deviation record is initiated\uff0c and the operator is trained and rectified. III. Third and Fourth Level Rechecks: QA\/Equipment Manager Periodic Random Inspection and Verification (Audit Recheck Layer)<br \/>\nFrequency: Randomly inspect no less than 1 unit daily, fully cover all negative pressure weighing rooms weekly, and conduct centralized review of all ledgers monthly.<br \/>\n(1) Cross-check of Paper Ledger<br \/>\nData Linkage Verification<br \/>\nCross-check the inspection records with other equipment ledgers to ensure logical consistency:<br \/>\nIf the long-term negative pressure is low \u2192 Verify the filter replacement records, monthly maintenance records for whether filter replacement or seal repair has been performed;<br \/>\nIf the record indicates glove damage \u2192 Check the spare parts requisition, maintenance replacement records;<br \/>\nAnnual PAO leak detection and instrument calibration certificates verify the validity of the inspection parameters (the instrument is within the calibration validity period, and the data is legal).<br \/>\nContinuous Cycle Verification<br \/>\nRandomly inspect for 7 consecutive days, check for any fake features such as batch pre-filling, uniform handwriting, and complete parameter fluctuations; Check if the invalidated records are completely retained, without tearing or missing pages.<br \/>\nRecord Compliance Audit<br \/>\nAre the modification norms, filling language, retention methods, and preservation period in line with GMP requirements?<br \/>\n(2) Surprise On-site Re-measurement Verification<br \/>\nQA conducts random inspections without notifying the workshop, retrieves the daily inspection sheet for on-site measurement:<br \/>\nNegative pressure, wind speed, seal, alarm, filter status, compare the record sheet, if the record does not match the actual situation, directly issue a deviation, assess the quality risk to material weighing.<br \/>\n(3) Monthly Summary Recheck<br \/>\nCount all record sheet defects in the current month: omissions, false records, abnormal issues not closed-looped, etc.;<br \/>\nSummarize frequent problems and organize on-site training, formulate corrective and preventive measures;<br \/>\nVerify if all deviations and maintenance work orders can be found in the corresponding source records in the inspection sheet.<br \/>\nIV. General Unqualified Standards for Recheck (any one of these criteria is not passed)<br \/>\nNegative pressure and wind speed only selected as normal, no actual measurement numbers;<br \/>\nParameters exceed the standard but not recorded, not explained, not handled;<br \/>\nSelected as abnormal, no description of the fault point;<br \/>\nLarge number of blank items, handover \/ abnormal remarks left blank;<br \/>\nPre-filled, signing on behalf of others, centralized filling of all records throughout the day;<br \/>\nModification without correction, without signature, severe alteration;<br \/>\nRecord data inconsistent with the actual state of the on-site instrument and equipment;<br \/>\nNo closed-loop for equipment failure, only problems without handling, no re-measurement;<br \/>\nMissing signatures of operators \/ recheckers.<br \/>\nV. Recheck Ledger Retention Requirements<br \/>\nThe team leader&#8217;s daily recheck signature is archived along with the inspection sheet;<br \/>\nQA conducts random inspections and establishes the &#8220;Record Sheet Recheck Inspection Ledger&#8221;, recording the inspection date, equipment number, identified defects, rectification results, and rechecker;<br \/>\nAll recheck materials are saved synchronously with the inspection records, with a retention period of no less than 1 year after the product&#8217;s expiration date, for drug regulatory audits to access.<br \/>\nVI. Simplified On-site Recheck Operation List (Available for the Team Leader to Carry)<br \/>\nComplete basic information, no blanks;<br \/>\nNegative pressure and wind speed have actual measurement values, matching the on-site instrument;<br \/>\nAll inspection items are selected, abnormal items have textual descriptions;<br \/>\nExceeding parameters have been recorded, handled, and re-measured data;<br \/>\nModification traces are standardized, with signatures;<br \/>\nComplete signatures of the operator;<br \/>\nThe on-site equipment status is consistent with the table description;<br \/>\nNo pre-filled, proxy signing, or fake traces;<br \/>\nThe team leader&#8217;s recheck signature confirms.<\/p>","protected":false},"excerpt":{"rendered":"<p>The standard process for reviewing and verifying the inspection records of the negative pressure weighing room (GMP Level 3 review) is divided into three levels: operator self-inspection, team leader on-duty review, and QA\/equipment staff regular spot-check verification.
