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
Anteroom
Connects the rest of the pharmacy to the buffer room. It has a sink, cabinets, and benches to facilitate garbing.
Running down the center of the room is the line of demarcation which separates clean from dirty sections (shoe covers must be applied one at a time while stepping over the line)
Segregated Compounding Area
A designated area with unclassified airflow, does not have a buffer area or ante room and can only be used for certain low-risk CSPs. The max BUD for compounds made here is 12 hours

C-PECs for hazardous Compounding: BSC
Biologic Safety Cabinet: have vertical laminar airflow and negative air pressure
Must be Class II or III for compounding of hazardous drugs
C-PECs for hazardous Compounding: CVE
Containment Ventilated Enclosures: are powder containment hoods with HEPA filtered air and negative pressure for non-sterile compounding only
C-PECs for hazardous Compounding: CACI
Compounding Aseptic Containment Isolators: Closed-front C-PECs (glovebox) that can be located in a buffer room
Non-sterile and Sterile HD Compounding in the same space
- C-SEC must maintain ISO 7 even when it is being use for non-sterile compounding
- If there are separate sterile and non-sterile C-PECs in the same C-SEC they must be at least 1 meter apart

- C-SCA must be at least 12 ACPH
Redundant HEPA Filters
Alternative to external exhaust (for non-sterile HD compounding only) is to use redundant HEPA filters. Air passes through two or more HEPA filters before being released.

Gloved fingertip test
Demonstrates adequate aseptic technique in hand washing, garbing, and gloving
- required initially and then annually if compounding low and medium risk CSPs
- required semi-annually if compounding high-risk CSP
Media-fill test
Demonstrates adequate aseptic technique in sterile drug preparation
- must be performed initially and a least annually for low and medium risk level
- Tryptic soy broth takes place of drug in the preparation
- Turbidity=contamination
- Passing =clear liquid after 14 days of incubation
Gloved fingertip test procedure
Evaluator collects a gloved sample from each hand of the compounder by rolling the pads of the fingers and thumb over a surface that has tryptic soy agair (TSA)
- plates are incubated
- spots that form are called colony forming units (CFUs) and indicate contaminationg
Passing a gloved fingertip test
Initial: requires 3 consecutive tests taken after garbing with zero CFUs for both hands
Ongoing: one sample from each hand after completion of media fill test with goal of <=3CFU total for both hands
Temperatures requirement
- SEC (buffer room) 20C or 68F or cooler (monitor once daily)
- Fridge 2-8C and Freezer -25 and -10, if freezer contains vaccines it must be -50 to -15 (monitor both twice daily)
Air Sampling
Should be performed at least every 6 months by a person certified in air sampling or by a qualified compounding staff member
-goals vary base on ISO; immediate action for highly pathogenic organisms (gram-neg rods, molds, yeasts)
Surface Sampling
- periodically
- goal is 0 CFU; action must be taken if:
- > 3 CFU in ISO 5
- > 5 CFU in ISO 7 or >100 CUF in ISO 8
- any growths of highly pathogenic organisms
Air Pressure
- check each shift (preferably) or daily (minimally)
- goals: non-hazardous cleanroom is positive and hazardous cleanroom is negative
