WORKER SAFETY: ICH Q7 GMP
ICH Q7 Resources and Materials Management: What Pharmaceutical Workers Need to Know
If you work in an API manufacturing facility, you handle materials that go into medicines taken by real patients. ICH Q7 sets the rules for how those materials must be received, stored, sampled, tested, and used. This guide explains what those rules mean for your daily work , in plain language, without the regulatory jargon.
Why This Matters to You
Every material that enters an API manufacturing process has the potential to affect the quality of the medicine that leaves it. A wrongly labelled container used in production can contaminate a batch. A raw material stored at the wrong temperature can degrade silently. An intermediate moved to the wrong area can be released without proper testing. ICH Q7 materials management rules exist because these failures have happened and caused patient harm. Your job in following these procedures is not just regulatory compliance , it is directly connected to patient safety.
Hazard Overview: What Can Go Wrong With Materials
Most Common Materials Management Failures in API Facilities
Using a material before it passes testing (released without QC approval)
Highest Risk
Using quarantined or untested materials in production is one of the most serious GMP violations. It can result in batch failure, contamination, product recall, and direct patient harm.
Label mix-ups and wrong material identification
Very Common
Using the wrong material, or using the right material from the wrong lot, because labels were not checked properly. Always verify the label against the batch record before adding any material to a process.
Storage conditions not maintained
Common
Materials stored outside their required temperature, humidity, or light conditions can degrade without visible signs of change. A material that looks fine but has been incorrectly stored may fail testing or compromise the API.
Cross-contamination from adjacent materials
Ongoing Risk
Materials stored or handled near incompatible materials, or without adequate segregation, can contaminate each other. Dust from one material can reach an open container of another. Segregation rules exist to prevent this.
Signs of Danger: When to Stop and Report
Label problems
Label is damaged, missing, illegible, or does not match what the batch record says. Label shows a status of “Quarantine” or “Rejected.” Container has no label at all. Any label discrepancy , stop, do not use, report to your supervisor immediately.
Container or seal damage
Container is cracked, punctured, swollen, or has evidence of moisture intrusion. Seal is broken, partially open, or appears tampered with. Any container integrity issue means the material inside may be compromised. Do not use until QC approves.
Appearance changes
Material colour, texture, smell, or particle size is different from what the specification or visual standard describes. Unexpected clumping, discolouration, or odour can indicate degradation or contamination. Report to QC before using.
Expired or re-test date exceeded
The material’s expiry date or re-test date has passed. Materials past their re-test date must be retested and approved before use. Do not assume that a material within the warehouse is current , always check the date before use.
Safe Work Practices: Your Step-by-Step Responsibilities
1
Check the label before touching the material
Before you pick up, move, weigh, or add any material, read the label. Confirm the material name, lot number, and status (Approved, Quarantine, Rejected). Compare what the label says to what your batch record, dispensing ticket, or work instruction requires. If anything does not match , the name, the lot number, the quantity, the status , stop immediately and ask your supervisor. Do not proceed on the assumption that the right material is in the right place. Label checks are the single most effective prevention for material mix-up errors.
2
Never use a quarantined or rejected material
Materials labelled Quarantine are awaiting testing or a release decision. They have not been approved for use. Materials labelled Rejected have failed testing or a quality decision. Neither can be used in production under any circumstance without a formal QU disposition. If you are ever asked to use a quarantined or rejected material by a production supervisor, do not comply. This is a serious GMP violation. Report the request to the Quality Unit immediately.
3
Follow storage requirements exactly
Every material has storage requirements listed on its label or in the inventory system. Temperature ranges, humidity limits, protection from light, and segregation requirements are not suggestions , they are specifications. When you put a material away, confirm it is going to the right storage location, at the right conditions. If a refrigerator or cold room temperature has alarmed, report it immediately and do not use materials from that area until QC has cleared them. Materials that have been out of their storage conditions must be reported, not quietly returned to storage.
4
Sample and weigh materials the right way
Sampling and weighing are high-risk steps where contamination, wrong material, and documentation errors most commonly occur. When sampling, use only the approved sampling tools for that material , shared or unwashed equipment can contaminate the sample. Weigh materials on calibrated balances using the approved procedure. Record the weight at the time of weighing, not from memory later. If you make an error during weighing, do not scratch it out , line through the error, write the correct value next to it, and initial and date the correction. Never write on a form in pencil or erase entries.
5
Handle containers to prevent contamination and mix-ups
When opening a container to sample or dispense material, do so in the designated area for that material. Do not open multiple different materials in the same area at the same time , airborne dust and particles can contaminate open containers nearby. Re-close and re-label containers after partial use. Never leave a container open and unlabelled. After working with one material, clean and clear the work area before setting up for the next material. This prevents carry-over contamination between materials even when they look similar.
PPE Requirements for Materials Handling
🧤
Gloves
Chemical-resistant gloves appropriate for the specific material. Check the SDS for glove material requirements , not all gloves protect against all chemicals. Change gloves between different materials to prevent cross-contamination.
😷
Respiratory Protection
Dust mask or respirator when handling powders or materials with inhalation hazards. Check the SDS for the required protection type. A standard surgical mask does not protect against chemical vapours or fine powders.
🥽
Eye Protection
Safety glasses or goggles when opening containers, sampling, or handling materials with splash or dust risk. Face shield when handling corrosive materials or large quantities.
🥼
Lab Coat or Coveralls
Cleanroom or production-grade garments as required for the area. Do not wear garments from one production area into a different area without following the gowning procedure. Contaminated garments must be changed before entering clean areas.
👞
Footwear
Chemical-resistant, anti-slip footwear for areas where spills may occur. Some areas require shoe covers or dedicated footwear that does not leave the production zone. Follow the site-specific footwear requirements for each area you enter.
📋
Check the SDS First
The Safety Data Sheet (SDS) for each material specifies the required PPE for that material’s hazard profile. The SDS is your primary reference for PPE selection. If you are unsure what PPE a material requires, ask before opening the container.
Do and Don’t: Materials Management Rules
Emergency Response: Materials Incidents
Chemical spill
Alert others in the area immediately. Check the SDS for spill response. Wear the PPE specified for spill response before attempting clean-up. For large spills or unknown materials, evacuate the area and call the emergency response team. Do not attempt to clean up a major spill alone.
Material exposure (skin or eye contact)
Flush immediately with water for at least 15 minutes at the nearest eyewash or safety shower. Call for help while flushing. Take the SDS with you to the medical clinic or emergency room so the treating clinician knows what the material is. Do not delay flushing to read the SDS first.
Wrong material used in production
Stop production immediately. Do not continue the batch. Report to your supervisor and the Quality Unit immediately with as much detail as possible about what was used and at what step. Do not try to correct the error yourself or complete the batch and hope the testing passes. This must be documented and investigated.
Supervisor Tips: Supporting ICH Q7 Materials Compliance on Your Team
Walk the warehouse and storage areas regularly
Labels degrade, containers shift, segregation breaks down. Regular walkthrough inspections of material storage areas catch problems before they reach production. Check that quarantine areas are physically segregated, that temperature logs are current, and that all materials are labelled with their current status.
Reinforce that reporting problems is expected, not punished
Workers who find a label discrepancy, a damaged container, or a temperature excursion must feel safe reporting it without fear of blame. A culture where problems are hidden is more dangerous than the problem itself. Make clear to your team that reporting materials issues early is the right thing to do and will be treated as such.
Never apply production pressure that compromises materials checks
A batch record that needs to be completed by end of shift is never a reason to skip a label verification, use an untested material, or omit a weighing record. As a supervisor, if you allow or apply pressure that results in materials management shortcuts, you bear responsibility for the consequences. Batch schedule pressure is never a justification for a GMP shortcut.
Worker Checklist: Before, During, and After Materials Handling
Before You Start
Read the work instruction or batch record before handling any material
Check the label on every container against the batch record
Confirm material status is Approved (not Quarantine or Rejected)
Check the re-test or expiry date
Put on the required PPE for this material
During the Task
Record all data at the time it happens, not from memory
Correct errors with a single line through, initialled and dated
Keep work area clear of other materials while working with one
Report any appearance change or container damage immediately
Do not leave containers open or unlabelled
After You Finish
Re-seal and re-label any partially used containers
Return materials to the correct storage location at correct conditions
Clean and clear the work area before the next task
Complete all records before leaving the area
Report any deviations or unusual events to your supervisor
Key Takeaways
The label check is not optional
Checking the label before every material use is the single most effective action you can take to prevent material mix-up errors. It takes seconds and it catches errors that no other control catches as reliably. Even if you placed the container there yourself, check the label before you use it.
Quarantined means not approved , no exceptions
A material labelled Quarantine or Rejected cannot be used in production under any circumstances. No schedule pressure, no verbal approval from a supervisor, and no “it’s probably fine” assumption changes this rule. If you are ever asked to use a quarantined material, report it to the Quality Unit. That request is itself a GMP violation.
Reporting problems protects patients and protects you
When you find a label discrepancy, a damaged container, a temperature excursion, or a wrong material, reporting it immediately is the right action. Reporting early gives QC the chance to investigate and contain the problem. Not reporting it means the problem propagates further, becomes harder to contain, and may reach patients. Reporting protects patients. It also protects you from being associated with a failure that could have been caught earlier.
Frequently Asked Questions
What should I do if I cannot read a label on a container?
Do not use the material. An illegible label means you cannot verify what is in the container. Report it to your supervisor and the Quality Unit immediately. The material must be re-evaluated, re-labelled, or tested before use. Do not attempt to identify the material by appearance, smell, or location. Guessing at the contents of an unlabelled container is not acceptable in GMP manufacturing, and doing so can introduce the wrong material into a batch with consequences that may only be detected at final testing or, in the worst case, after the medicine reaches a patient.
Can I use a material if it is past its re-test date but not past its expiry date?
No, not without QC authorisation. A material past its re-test date must be retested and receive a new approval before it can be used. The re-test date and the expiry date serve different purposes: the re-test date is the point at which the material’s quality must be re-confirmed, regardless of the longer expiry date. Using a material past its re-test date without retesting is a GMP violation even if the material looks fine and the expiry date has not been reached.
What is FIFO and why does it matter for materials management?
FIFO (First In, First Out) means older stock is used before newer stock of the same material. This prevents materials from sitting past their re-test or expiry dates while newer lots are used first. Check lot dates when picking materials and always use the older lot. FIFO is a GMP requirement under ICH Q7.

Handling Materials Right Is Handling Patients Right
Every material decision you make in an API facility is a step in a chain that ends with a patient. A label check that takes five seconds, a report about a damaged container, a decision not to use a quarantined material under pressure , each of these matters to someone at the end of that chain. ICH Q7 materials management is not paperwork. It is the practical expression of the commitment that the medicine a patient receives is what it is supposed to be.
