Restricted Access Barrier System (RABS)
RABS are aseptic processing systems (ISO 5) intended to substantially reduce human borne contamination within the aseptic environment where sterile product, containers, closures and equipment are exposed by the use of separative devices and defined mechanical features and operating procedures. (TR22) (TR62) Aseptic processing systems (ISO 5) intended to substantially reduce human-borne contamination within the aseptic environment where sterile product, containers, closures, and equipment are exposed by the use of separative devices and defined mechanical features and operating procedures.

Technology Transfer
Isolator, Open
A decontaminated unit meeting ISO 5 conditions that provides uncompromised, continuous, isolation of its interior from the surrounding environment. It may transfer air directly to the surrounding environment through openings (e.g., “mouse holes”) that preclude the ingress of microbial contamination. (TR13) (TR22) (TR62)

Critical Area/Critical Zone
An area designed to maintain sterility of sterile materials. Sterilized product, containers, closures, and equipment may be exposed in critical areas. (TR13) (TR22) (TR44) (TR62)

Bioburden
The total number of microorganisms per unit of material prior to sterilization. (TR13) Total number of viable microorganisms on or in a health care product prior to sterilization. (TR22)(TR61)(TR62) A population of viable microorganisms in a fluid prior to sterilizing filtration. (TR26) A measure of the contaminating organisms found in or on a given amount of material before it undergoes a sterilization process. (TR45) (TR70) The number of detectable microorganisms (bacteria and fungi) with which an object is contaminated. It is measured in CFU (colony forming units). (TR47) The number of viable, contaminating microorganisms present on a product immediately prior to decontamination. (TR51) Viable microbial contaminants associated with personnel manufacturing environments (air and surfaces), equipment, product packaging, raw materials (including water), in-process materials, and finished products.

Alert Level
An established microbial or nonviable particle level giving early warning of potential drift from normal operating conditions; not necessarily grounds for definitive corrective action but typically requires follow-up investigation. (TR13) (TR22) (TR69)
An established level that, when exceeded, is giving an early warning of a potential drift from normal operating conditions; while not necessarily grounds for definitive corrective action, it typically requires follow-up review. (TR 60)
An established microbial or nonviable particle level giving early warning of potential drift from normal operating conditions; not necessarily grounds for definitive corrective action, but typically requires follow-up investigation (3, 4, 7). (TR88)

Action Level
An established microbial or airborne particle level that, when exceeded, indicates a process is outside of its normal operating range. A response to such an excursion should involve a documented investigation and corrective actions based on the results of that investigation. (TR13)
An established microbial or non-viable particle level that, when exceeded, should trigger appropriate investigation and corrective action based on the investigation. (TR22)
An established microbial or airborne particle level for environmental, water or gas monitoring that, when exceeded, indicates that a facility process is outside of its normal operating range. The response to such an excursion involves a documented investigation and corrective actions based on the results of that investigation. The prescribed action level is often specified in guidance or standards relating to environmental monitoring and water quality. (TR69)
An established microbial or nonviable particle level for environmental, water, or gas monitoring that, when exceeded, indicates a facility or process is outside of its normal operating range. The response to such an excursion may involve a documented investigation and corrective actions based on the results. The prescribed action level is often specified in guidances or standards relating to environmental monitoring and water quality (3-6). (TR88)
