In glass distribution, quality assurance and control aren’t just about product inspection—they’re about protecting trust. This blog recounts an incident where lax QA/QC procedures caused a shipment of defective glass to reach a government facility, triggering major reputational damage and a full audit.
The Incident: Delaminated Glass Shipped to a Government Training Center
A Canadian distributor delivered custom laminated panels for a federal training center’s interior conference rooms. Within days of installation, staff noticed bubbles forming at panel edges. An investigation revealed the issue was due to expired interlayer materials used during lamination—an issue that should have been caught during QA review.
Further inspection revealed that the vendor’s batch records were incomplete and that visual inspection was the only step consistently enforced.
Audit Breakdown Highlights
No expiration tracking or rotation system was in place for time-sensitive materials
QA logs lacked proper lot number identification or adhesive test results
Incoming vendor material was assumed compliant without verification
Consequences
$95,000 in product replacement and service labor
Temporary facility closure and federal compliance inquiry
Blacklisting from future public sector bids for 12 months
Remedial Measures
Material Lot Tracking Enforced
Every component now includes lot numbers and expiration data, tracked across receiving, production, and shipment.
Quality Control Log Digitization
QA forms have been digitized and integrated with barcode scanning, tying each final product to a full inspection trail.
Third-Party QA Audits Scheduled Quarterly
All major projects now include periodic third-party inspections of both incoming and outgoing products.
Final Thought
Quality isn’t just about the visible—it’s about what’s traceable. QA systems must be structured to detect risks before the client ever opens the box.
