Quarantine

Quarantine designates the controlled storage status applied to materials, products, or equipment preventing use or distribution until quality evaluation, testing, or investigation completion determines acceptability. This critical quality control measure physically or electronically segregates quarantined items, clearly identifying their restricted status through labels, designated areas, or computerised systems preventing inadvertent use. Quarantine applies to incoming raw materials awaiting testing, in-process materials pending evaluation, finished products before final release, returned goods, or items under investigation.

The pharmaceutical industry implements comprehensive quarantine systems ensuring only approved materials enter manufacturing and products meeting specifications reach patients. Physical segregation employs dedicated quarantine areas with restricted access and clear identification. Electronic quarantine systems use computerised controls preventing material release until testing completion and quality approval. Raw material quarantine prevents untested materials from entering manufacturing, with sampling and testing determining acceptability. In-process quarantine controls intermediates pending analytical results. Finished product quarantine holds products until comprehensive quality review and batch disposition decision. Regulatory requirements mandate quarantine systems preventing unapproved material use. As supply chains become more complex, electronic systems replace physical controls, and inventory pressures increase, quarantine management continues evolving through sophisticated tracking systems and robust procedures ensuring material and product integrity.
