Pre-control: Ensure the authenticity and completeness of records from the source<br \/>\n1. Define job responsibilities and assign them to individuals<br \/>\nOperator&#8217;s primary responsibility: Pre-checking before startup, observing parameters during operation, confirming cleaning at the end of the shift, filling in immediately during the shift, prohibiting filling after the shift or making up entries the next day.<br \/>\nTeam leader&#8217;s review responsibility: Before each shift ends, check each record item one by one, verify abnormalities and blank items on the spot.<br \/>\nQA inspection supervision: Conduct on-site random checks daily, compare real-time equipment parameters with paper records.<br \/>\nEquipment administrator&#8217;s archiving review: Recycle ledgers weekly, uniformly check for completeness, and hold accountable for missing records.<br \/>\n2. Standardize record forms to prevent omissions<br \/>\nFixed mandatory items in the template: Negative pressure and wind speed must have a numerical filling column, not just a checkmark for normal\/abnormal;<br \/>\nEach inspection item is listed separately in a row, without merging large blank columns to prevent deliberate skipping;<br \/>\nSet mandatory columns: Date, shift, start\/stop time, operator, reviewer, abnormal description area. Blank indicates incomplete record;<br \/>\nSupport on-site signboards: Post inspection standards and record filling requirements beside the weighing room to facilitate employees&#8217; reference.<br \/>\n3. Provide on-site hardware support to facilitate real-time data collection (ensuring data accuracy)<br \/>\nPressure differential meters and wind speed indicators are installed in positions visible to the operators, no need for estimation while moving;<br \/>\nEquip fixed wind speed meters for fixed storage, measure the operating port wind speed for each shift, prohibit estimating based on experience;<br \/>\nRegularly calibrate instruments (monthly calibration of pressure differential sensors, annual calibration of wind speed meters), avoid data distortion of the instruments leading to record errors;<br \/>\nAttach calibration labels to the instruments, indicating the validity period, and prohibit using expired instruments or recording data.<br \/>\nII. Filling Norms System to Ensure Accurate and Compliant Records<br \/>\n1. Real-time filling, prohibit post-event supplementation or pre-filling<br \/>\nStrict regulations: Fill one item for each inspection, record parameters immediately after the startup is completed, do not fill the entire shift at once;<br \/>\nProhibit pre-filling blank record sheets or proxy filling others&#8217; records; QA inspection finds pre-filling or proxy filling, directly issue a deviation.<br \/>\n2. Unified data filling standards<br \/>\nQuantitative parameters (negative pressure, wind speed): Must fill in the measured numbers, such as negative pressure &#8211; 22Pa, wind speed 0.38m\/s, only writing &#8220;normal&#8221; is considered incomplete record;<br \/>\nQualitative inspection items (gasket, fan, gloves, filter screen): Check &#8220;normal&#8221; or &#8220;abnormal&#8221;, abnormal must be specified in a dedicated column (e.g., slight cracking of door gasket, excessive dust on return air filter), only checking abnormal without description is considered unqualified;<br \/>\nClear handwriting, use black signature pens, no pencils or correction fluids for correction;<br \/>\nData error modification rules: Cross out the incorrect value with two lines, write the correct value above, sign the name + modification time at the modification place, prohibit blackening and covering.<br \/>\n3. Prohibit blank item management<br \/>\nNo data, no inspection, no measurement columns must not be left blank;<br \/>\nUnused equipment on the current day should be marked: &#8220;This shift has no production, equipment is idle, not running&#8221; and signed;<br \/>\nEquipment failure shutdown: Specify the reason for shutdown and the shutdown time, do not skip inspection items with blank entries;<br \/>\nShift handover remarks, abnormal description column, no abnormalities should be uniformly filled in &#8220;No abnormalities&#8221;, no blank spaces allowed.<br \/>\nIII. Process Rechecking and On-site Comparison to Verify Data Authenticity<br \/>\n1. Three-level rechecking mechanism<br \/>\nFirst-level self-check (operator): Read and review the entire form, check for any omissions or significant deviations from the standard (such as negative pressure &#8211; 5Pa, wind speed 0.6m\/s without marking abnormal), and sign again if no errors are found;<br \/>\nSecond-level in-shift recheck (team leader): Conduct two-point on-site rechecks before each shift ends: \u2460 Compare the current reading of the pressure difference gauge with the recorded values in the table to ensure consistency;<br \/>\n\u2461 Check item by item whether all the inspection items have been filled in and whether there are any descriptions of abnormalities;<br \/>\nThird-level regular inspection (QA \/ Equipment Operator)<br \/>\nRandomly inspect 1 to 2 weighing rooms daily: Measure the negative pressure and wind speed on-site and compare them with the records of the current shift;<br \/>\nExtract historical records for 3 days and trace the equipment maintenance and filter replacement records during the same period to cross-verify whether the logic is consistent.<br \/>\n2. Closed-loop verification of abnormal data (to prevent concealment and distortion)<br \/>\nWhen an abnormal parameter appears in the record sheet (negative pressure &lt; -15 Pa, wind speed exceeds 0.35 &#8211; 0.45 m\/s, abnormal noise from the fan, air leakage, etc.), the following three things must be completed simultaneously:<br \/>\nIn the &#8220;Abnormal Explanation Column&#8221;, describe the phenomenon completely;<br \/>\nRecord the on-site handling measures (stop the machine \/ clean the filter \/ adjust the door seal \/ report for maintenance);<br \/>\nAfter maintenance \/ handling, re-measure the data and fill it in the remarks column;<br \/>\nOnly record the abnormalities, without handling or re-measurement results, and determine that the record is incomplete, and initiate a minor deviation.<br \/>\nFour. Ledger archiving management to avoid loss and missing pages<br \/>\nThe record sheet is bound in chronological order by equipment number and date, one book corresponding to one weighing room, and divided by month;<br \/>\nAt the end of each day, the team leader collects them uniformly, and it is prohibited to leave the record sheets on the site for a long time and cause loss or damage;<br \/>\nEstablish a ledger borrowing registration: Record the issuance of the record sheet number, keep the invalidated records completely, and do not tear them up;<br \/>\nStore in a dry and light-protected environment to prevent blurred handwriting and page damage, resulting in information loss;<br \/>\nThe retention period is strictly implemented: At least 1 year after the product expiration date, and the audit can fully retrieve records for any date.<br \/>\nFive. Personnel training and assessment to reduce human errors<br \/>\nSpecial training for new employees before onboarding: Record sheet filling requirements, parameter standards, modification norms, key points of abnormal filling, etc., and only allow independent operation after passing the assessment;<br \/>\nConduct a review training once a month: Summarize the common problems in the records of the current month (omission of wind speed, no description of abnormalities, proxy filling, pre-filling), and correct on-site examples;<br \/>\nIntegrate record completeness and accuracy into job performance assessment:<br \/>\nIf there are multiple omissions, false records, proxy filling, etc., conduct re-training for the position;<br \/>\nRepeat violations trigger training, assessment, or performance penalties.<br \/>\nSix.
