Critical areas ISO requirement
USP 797
Critical areas are those that are closest to exposed sterile drugs (hood, PEC) and container, are quality must be at least ISO 5.
This means that there are no more than 3,520 particle per cubic meter. Particles are included in this count if they are 0.5 microns (micrometer) or larger
Buffer area ISO requirement
USP 797
ISO 7
Anteroom ISO requirement
USP 797
ISO 8 if it opens to a positive pressure buffer area and ISO 7 if it opens into a negative pressure buffer area
Anteroom is where hand washing and garbing occurs
High-Efficiency Particulate Air Filters
HEPA filters are >99.97% efficient in removing particles as small as 0.3 microns wide or larger
Vertical Airflow biologic safety cabinet (BSC) or C-PEC
the HEPA filter is at the top of the sterile hood
Laminar Airflow Workbench (LAFW) or PEC
Also called a horizontal airflow hood the HEPA filter is at the back of the hood
Air pressure for non-hazardous compounding
Positive air pressure in the PEC and SEC because the air will not cause toxicity if it moves into adjacent spaces
Air pressure for hazardous compounding
C-PEC and C-SEC must have negative pressure to contain and exhaust the toxic air in the space.
The negative air pressure protects the compounding staff
Cleanroom Suite
One or more sterile hoods (ISO 5 PECsO inside an ISO 7 buffer room (SEC) that is entered through an adjacent anteroom
Segregated Compounding Area
SCA
With and ISO 5 PEC: a sterile hood, often and isolator (glovebox) with a closed front, located in a segregated space with unclassified air
Primary Engineering Control
PEC
IS a device or room that provides ISO 5 environment for sterile compounding. The most common way to achieve ISO 5 is by using a sterile hood.
PECs for non-hazardous sterile preparations
- Laminar airflow workbench
- A compounding aseptic isolator
Secondary Engineering Control
SEC
Is the room that contains the PEC, it is commonly called the buffer area. Provides a “buffer” of clean air (ISO 7) around the PEC
