C-SEC stands for

• A. Containment Secondary Engineering Control - separate externally vented room / CASA
• B. Containment Primary Engineering Control - BSC / machine
• C. Closed-System Transfer Device
• D. Ultra-Low Particulate Air filter

Answer: (A)

In hazardous drug handling, containment works in two levels: a primary engineering control where the compounding happens, and a secondary engineering control that surrounds and contains the whole setup. C-SEC stands for Containment Secondary Engineering Control, which refers to a separate, externally vented room or area that provides an additional containment barrier around the primary device and helps exhaust any airborne contaminants away from staff and other areas. This secondary space is typically designed to maintain negative pressure relative to adjacent areas, enhancing overall safety. The primary engineering control is the device used for the actual preparation (like a biosafety cabinet or containment isolator), while the secondary control is the surrounding room. The other options describe either the device itself, a transfer device, or a filtration component, none of which match the concept of a containment-focused room or area surrounding the primary device.
