Pharmaceutical Compound Containment
Compounding pharmacies handle high-risk drugs that necessitate strict adherence to C-PEC (Containment Primary Engineering Control) and C-SEC (Containment Secondary Engineering Control). Diagnostics here focus on ensuring the primary enclosure (hood) is effectively exhausting into the building’s dedicated redundant exhaust system.
The Hazard Migration Path
Hazardous Drugs (HD) containment relies on a double-layer strategy. The C-PEC (hood) acts as the first barrier, and the C-SEC (the room itself) acts as the secondary barrier. Containment failure occurs when the C-SEC exhaust is under-pressured, creating a “dead zone” where drug vapors collect instead of exhausting.
| Facility Component | Pressure Requirement | USP 800 Control |
|---|---|---|
| C-PEC (Hood) | -0.01 to -0.03″ w.c. | Primary Hazard Trap |
| C-SEC (Room) | Negative Relative to Corridor | Containment Boundary |
| Ante-Room | Positive relative to C-SEC | Transition Buffer |
Diagnostic Gateway Challenge
You are verifying a C-SEC room. The primary hood (C-PEC) is operational at 400 CFM, but the room pressure differential is 0 Pa (Neutral). What is the primary containment failure?
