300Q: Batch Records + Equipment + Calibration + Maintenance

What is a batch record?

A batch record is a controlled document that records all manufacturing activities for a specific batch.

Why is a batch record important?

It provides complete traceability and evidence that the batch was manufactured according to approved procedures.

Who completes batch records?

Trained production personnel complete batch records during manufacturing.

When should batch records be completed?

Batch records should be completed contemporaneously as activities are performed.

Who reviews batch records?

Production and Quality personnel review batch records before batch release.

What is the purpose of batch record review?

To verify completeness, accuracy, and compliance with GMP requirements.

What should be done if information is missing in a batch record?

The issue should be investigated and documented according to procedures.

How do you correct an error in a batch record?

Draw a single line through the error, enter the correct information, sign, date, and provide a reason if required.

Why are signatures required in batch records?

They provide accountability and traceability.

What information must be recorded in a batch record?

Materials, equipment, process parameters, IPC results, dates, times, and signatures.

What is equipment qualification?

Documented evidence that equipment is suitable for its intended use.

What are the stages of equipment qualification?

Installation Qualification, Operational Qualification, and Performance Qualification.

What is Installation Qualification (IQ)?

IQ verifies that equipment is installed correctly according to specifications.

What is Operational Qualification (OQ)?

OQ verifies that equipment operates as intended within defined limits.

What is Performance Qualification (PQ)?

PQ verifies that equipment performs effectively under routine operating conditions.

Why is equipment qualification important?

It ensures equipment consistently produces reliable results.

How do you verify equipment status before use?

We check the equipment status label and equipment logbook.

What information is included on an equipment status label?

Equipment ID, status, date, and responsible person.

What should you do if equipment status is unclear?

Do not use the equipment until its status is confirmed.

What is an equipment logbook?

A record of equipment usage, cleaning, maintenance, and repairs.

Why are equipment logbooks important?

They provide traceability and equipment history.

What is calibration?

Calibration is the comparison of an instrument against a known standard.

Why is calibration important?

It ensures measurement accuracy and reliability.

How do you verify calibration status?

By checking the calibration label and calibration records.

What information is found on a calibration label?

Calibration date, due date, and instrument identification.

Can equipment be used after the calibration due date?

No. Equipment cannot be used if calibration is overdue.

What should you do if calibration has expired?

Stop using the equipment and report the issue.

What is preventive maintenance?

Scheduled maintenance performed to prevent equipment failure.

Why is preventive maintenance important?

It improves equipment reliability and reduces downtime.

How is preventive maintenance scheduled?

According to approved maintenance plans.

Who performs preventive maintenance?

Qualified maintenance personnel perform preventive maintenance.

How is maintenance documented?

Maintenance activities are recorded in maintenance records or logbooks.

What is corrective maintenance?

Maintenance performed to repair equipment after a failure occurs.

What should happen if equipment breaks down during production?

The equipment should be stopped, assessed, and the impact on product quality evaluated.

How do you assess the impact of equipment failure?

We evaluate affected batches, process conditions, and product quality risks.

What is equipment cleaning?

The removal of residues and contaminants from equipment surfaces.

Why is equipment cleaning important?

It prevents contamination and ensures product quality.

How do you verify equipment cleanliness?

Through visual inspection and approved verification procedures.

What records document equipment cleaning?

Cleaning logbooks and cleaning records.

What is equipment dedication?

Assigning equipment to a specific product or process.

When is dedicated equipment required?

When required to control contamination risks.

How do you ensure equipment remains fit for use?

Through qualification, calibration, maintenance, and cleaning.

What is an instrument?

A device used to measure process parameters or product attributes.

Why are measuring instruments critical?

They provide data used for quality and process decisions.

How do you handle damaged instruments?

They are removed from service and evaluated.

What should you do if an instrument gives unexpected results?

Stop using it and investigate the issue.

How do you control spare parts for critical equipment?

Approved spare parts are identified and managed through a controlled system.

What documentation supports equipment lifecycle management?

Qualification, calibration, maintenance, cleaning, and change control records.

How do inspectors typically evaluate equipment management?

By reviewing qualification documents, maintenance records, calibration status, and equipment logbooks.

How do you demonstrate equipment compliance during an inspection?

We provide qualification records, calibration records, maintenance records, and equipment logbooks showing current compliant status.
