C-PEC stands for which term?

• A. Containment Primary Engineering Cabinet
• B. Containment Primary Engineering Control
• C. Containment Primary Environmental Chamber
• D. Containment Public Engineering Cabinet

Answer: (B)

The concept being tested is the specific term used for the device or enclosure that directly contains hazardous drug manipulations. Containment Primary Engineering Control refers to the primary piece of equipment used during compounding, such as a Class II biological safety cabinet or a Containment Isolator, that provides the immediate containment at the point of use. It’s designed to prevent exposure to staff and to keep the drug-containing aerosols or splashes within the enclosure.

The “containment” part emphasizes that this control is dedicated to preventing release into the surrounding area. “Primary” indicates it’s the first barrier at the worksite where the hazardous drug is handled. “Engineering Control” means it is a mechanical/environmental control, not an administrative measure.

In contrast, the Secondary Engineering Control is the surrounding room or space that houses the primary device and provides environmental conditions (like negative pressure and appropriate air changes) to maintain overall containment. This distinction helps explain why the correct term is Containment Primary Engineering Control.
