Streamlined Laboratory Decommissioning and Facility Closure

At CFS Site Services, every decommissioning project begins with critical cleaning of laboratory equipment, cleanroom environments, and associated support spaces to ensure all surfaces are free of chemical, biological, and particulate residues. Our approach emphasizes precision cleaning, risk mitigation, and thorough documentation—leaving facilities safe, compliant, and fully prepared for turnover.

We specialize in laboratory, vivarium, and cleanroom decommissioning services, delivering solutions aligned with GMP requirements, FDA expectations, ISO 14644 cleanroom standards, and ANSI/ASSE Z9.11 guidelines. Our experienced technicians manage each phase of the decommissioning process, including equipment disassembly, detailed surface wipe-downs, HEPA-filtered vacuuming, particulate removal, environmental monitoring, and clearance sampling.

All activities are supported by comprehensive documentation and final closeout reporting, creating a clear, traceable audit trail suitable for regulatory inspections, internal quality reviews, and real estate transfer requirements. Whether supporting relocations, consolidations, facility closures, or tenant turnover, our Bay Area and nationwide decommissioning services deliver a seamless, compliant, and cost-effective transition—protecting personnel, operations, and organizational reputation.

CFS Site Services provides specialized decontamination and verification services to ensure laboratories, vivariums, and cleanrooms are fully sanitized, compliant, and ready at the time of closure. Our structured approach includes hydrogen peroxide fogging, targeted surface swabbing, and comprehensive environmental monitoring to confirm that spaces and equipment meet applicable regulatory and safety requirements.

Our technicians are trained to perform surface and air sampling, viable and non-viable particle testing, and verification monitoring in alignment with GMP expectations, FDA requirements, and ISO 14644 cleanroom standards. Each activity is executed using documented procedures to deliver objective, measurable evidence that contamination has been effectively eliminated.

Every project is supported by detailed certification and closeout reports, including sampling methodologies, test results, environmental data, and full traceability. Whether preparing for facility closure, tenant turnover, relocation, or regulatory inspection, our Bay Area and nationwide decontamination and verification services deliver scientifically validated, audit-ready results that provide confidence to EHS, QA, and property stakeholders.

At CFS Site Services, we understand that a decommissioning project is only complete when it is fully documented, certified, and defensible. Our process includes the development of comprehensive decommissioning reports and formal closure documentation aligned with ANSI/ASSE Z9.11 guidelines, GMP requirements, FDA expectations, and ISO 14644 cleanroom standards.

Each report provides a traceable, end-to-end record of all decommissioning activities, including equipment disassembly and cleaning, environmental monitoring, surface and air sampling results, verification testing, and any corrective actions performed. This documentation serves as a regulatory-ready compliance record, supporting inspections, internal quality audits, EHS reviews, and real estate transactions.

In addition to execution and reporting, our team offers consultative support to help clients interpret ANSI/ASSE Z9.11 requirements, develop site-specific decommissioning protocols, and implement closure strategies that minimize risk and liability. By combining technical expertise with robust documentation and advisory support, CFS Site Services delivers full compliance, transparency, and confidence throughout the decommissioning process.
