A quarantine area is a designated physical or system-controlled location where material, parts, product, tooling, or other items are held apart from normal use, movement, or shipment until their status is resolved.
In manufacturing and quality workflows, quarantine areas are commonly used for incoming material awaiting inspection, suspected nonconforming product, items under quality hold, or inventory pending review by quality, engineering, or material review personnel. The area may be a marked cage, shelf, room, warehouse location, or a logical inventory status in an ERP, MES, QMS, or WMS.
A quarantine area does not automatically mean the item is rejected or scrap. It means the item is restricted until a disposition is made, such as release, rework, return to supplier, use-as-is approval, or scrap. The key distinction is segregation and status control, supported by identification, traceability, and records that show why the item is held and who is authorized to change its status.
