Dispensing and verification — jurisdiction-specific requirements
For US finished pharmaceutical manufacturing, 21 CFR 211.101(c) requires a second-person examination of each dispensed component container for release status, correct weight or measure, and proper identification, with a specified exception for weighing, measuring or subdividing performed by automated equipment under 21 CFR 211.68. Under 21 CFR 211.101(d), component addition requires second-person verification for manual addition; a defined single-person verification applies when the operation is performed by qualifying automated equipment.
Other jurisdictions and product categories may differ. Follow applicable regulations and approved procedures rather than treating every independent check as optional based only on site risk.

Text descriptions of the main slide relationships, in presentation order. Use these with the narration transcript and companion reading. Arrows summarize relationships; they do not replace site procedures or prescribe a universal workflow. The repeated right-hand panels are reminders, not additional mandatory steps.
- Manufacturing control: approved instructions, execution and review.
- Material status has distinct quarantine, released and rejected states. Verify records, not only container labels.
- Dispensing connects material identity, measurement and recording. Perform applicable independent checks and maintain batch traceability.
- Line clearance: clear the area, check setup and authorize the operation under approved procedures.
- In-process control loop: measure, compare with approved limits, then respond and record.
- Batch records connect operations, in-process data and reconciliation; investigate unexplained gaps.
- Deviation response: secure, report and assess while preserving evidence.
- Conflicting status: a released label and a system hold are inconsistent. Hold the material and escalate; do not select the preferred status.

Transcript of the revised recording, 26 October 2026. The companion reading adds further detail.
00:00:00 Good Manufacturing Practice requires manufacturing operations to follow approved
00:00:04 instructions and appropriate controls. Processes should be defined, suitable for
00:00:09 their intended purpose, and performed by trained personnel.
00:00:13 Controls must address potential contamination, mix-ups and errors throughout the
00:00:17 process. This introductory lesson explains common operating principles.
00:00:23 Specific requirements depend on the product, dosage form and manufacturing
00:00:26 process. Incoming starting materials and packaging components should be
00:00:31 received, identified, and controlled according to approved procedures.
00:00:37 Appropriate quarantine and release arrangements help prevent unintended use.
00:00:41 Storage conditions and stock rotation should reflect material requirements.
00:00:46 Before dispensing, personnel should verify material identity, status and
00:00:51 suitability. A label alone may not be sufficient when supporting records
00:00:55 indicate a discrepancy. Dispensing involves selecting and measuring the correct
00:01:00 approved materials for a defined batch. Operators should follow authorized
00:01:05 instructions, use suitable calibrated instruments, and document quantities and
00:01:09 material identities. Applicable independent checks must be performed.
00:01:14 European Union GMP requires an independent check of each dispensed material and
00:01:20 its weight or volume, with the check recorded.
00:01:22 United States regulations specify second-person checks, with defined exceptions
00:01:28 for qualifying automated equipment. A local risk assessment does not waive
00:01:34 applicable requirements. Traceability connects each dispensed material to its
00:01:39 source and the batch in which it is used. Before manufacturing begins, line
00:01:44 clearance and setup checks help ensure that previous materials, labels,
00:01:48 documents and residues do not create mix-up or contamination risks.
00:01:53 The equipment, area and materials should be confirmed suitable for the planned
00:01:57 operation. Checks must follow approved procedures and be recorded as required.
00:02:03 The exact sequence and verification method depend on the facility and process.
00:02:08 In-process controls provide information about the state of a manufacturing
00:02:12 process while it is running. Examples may include weight, volume, temperature,
00:02:18 pressure, pH, appearance or other process-specific measurements.
00:02:23 Monitoring frequency, limits and response actions must come from the approved
00:02:27 process and supporting scientific justification.
00:02:31 There is no single universal acceptance criterion that applies to every
00:02:35 pharmaceutical process. Batch manufacturing records provide traceable evidence
00:02:40 of the actual operations performed. Entries should identify relevant materials,
00:02:45 equipment, operators, times, process observations and checks as required by the
00:02:51 approved record. Reconciliation can help detect unexplained differences in
00:02:56 quantities or printed materials. Documentation must reflect what occurred,
00:03:01 including deviations, and must not be completed retrospectively from guesswork.
00:03:07 Unexpected process results, equipment alarms or procedural departures should be
00:03:11 handled under the site quality system. Operators should secure the process as
00:03:16 appropriate, report the event and preserve relevant data.
00:03:20 Authorized personnel assess product impact and determine investigation,
00:03:25 disposition and corrective actions. A result that later returns to normal does
00:03:30 not automatically eliminate the need to document and evaluate the original
00:03:34 event. Imagine an operator preparing to start a batch who discovers that a
00:03:39 container of starting material has a released label but the electronic inventory
00:03:44 record still shows quarantine status. The operator should not choose whichever
00:03:49 status seems convenient. The material should be held from use while authorized
00:03:54 personnel reconcile the discrepancy under approved procedures.
00:03:58 This illustrates why status verification, traceability and escalation matter
00:04:04 before manufacturing begins.
