USP <800> Explained

Terms Applicable to USP <800> Standards:


Containment Primary Engineering Control

A ventilated device designed to minimize worker and environmental hazardous drug exposure when directly handling hazardous drugs.


Containment Secondary Engineering Control

The designated room where the C-PEC is situated. It ensures the environment around the C-PEC remains controlled and secure.


Hazardous Drugs

Pertains to the toxic powder or active pharmaceutical ingredient that is handled within specific containment measures, ensuring safety for both workers and the environment.


High-Efficiency Particulate Air Filter

HEPA Filters are designed to capture and remove airborne particles, with at least 99.995% effectiveness.


Air Changes Per Hour

Complete air replacements that occur within a Containment Secondary Engineering Control (C-SEC).


Contained Vented Enclosure

A specialized, vented containment enclosure ensures both personnel and environmental protection.

Class I BSC

Biological Safety Cabinet

A Class I BSC is a containment enclosure that safeguards both personnel and the environment.


Compounding Aseptic Isolator​

Provides aseptic conditions while preparing sterile medications, ensuring personnel safety.


Compounding Aseptic Containment Isolator​

Provides sealed aseptic conditions for sterile compounding, ensuring personnel AND product safety.

Requirements for Non-Sterile HazarDous Compounding

Ensuring Safe & Effective Practices

At Flow Sciences, we recognize the significance of adhering to the requirements in HD compounding. Our expertise and comprehensive range of solutions empower you to achieve the utmost safety, compliance, and efficiency. Count on us to be your partner in upholding the highest standards in hazardous drug handling.

C-PEC ventilation requirements depend on the application. It can be externally vented (preferred) or redundant HEPA-filtered in series. Examples: CVE, Class I BSC, CAI or CACI

C-SEC MUST be externally vented AND have at least 12 ACPH. Externally vented, ≥ 12 ACPH, Negative pressure between 0.01 and 0.03 inches of water column relative to adjacent areas. Requirements vary based on application.

Variety of C-PEC Options: Flow Sciences offers an array of C-PEC solutions, including our time-tested CVE, Class I Bio-Safety Cabinets, and Compounding Aseptic Containment Isolators. Among these, our CVE paired with Single or Dual HEPA filtration units (dependent on application) stands out as an efficient solution to USP <800> compliance.
