A worldwide life sciences supplier of micro-array technologies occupied a leased space of approximately 40,000 square feet including research and development, manufacturing, and general office space. The client was in the process of relocating these operations to its California facility and hired CAPACCIO to prepare a decontamination protocol, oversee the decontamination conducted by a hazardous waste contractor, and prepare a decontamination report documenting the facility closure and decontamination for submittal to state and local officials.

CAPACCIO met with the client while the operations were active to understand the types of chemical and biological agents in use at the facility. In addition, CAPACCIO met with facility representatives, reviewed environmental permits, and conducted pre-decommissioning wipe sampling of selected surfaces throughout the facility including manufacturing and office space areas. Using a direct-contact media test, wipe samples were collected and sent to a laboratory where a non-selective agar was used as an incubation media. After 48-hours, the number of colony-forming units (CFUs) on each plate were counted, which provided the ability to identify a broad spectrum of bacteria including gram-positive spore forming rods, gram-positive cocci, gram-positive rods, molds, and fungi.

By conducting the pre-decommissioning sampling on surfaces in manufacturing, office space, and a control surface, CAPACCIO established the background levels for the facility and used this information in determining the decontamination techniques and cleaning agents necessary during the decontamination process. This level of detail provided specific cleaning instructions and desired outcomes for the client to solicit quotes from cleaning contractors. In addition, the detailed decontamination plan provided clear objectives for the level of cleaning required and the requirements for the final surfaces.
