What is a containment secondary engineering control (C-SEC) and its purpose?

• A. A small benchtop glove box inside the C-PEC
• B. A dedicated room or area with appropriate ventilation that provides added containment for HD work, separating it from non-HD spaces
• C. A storage cabinet with nominal ventilation
• D. A portable air purifier without room ventilation

Answer: (B)

Containment secondary engineering controls create an added layer of protection by using a dedicated, ventilated space to house hazardous drug work, separate from non-HD areas. This room or area provides appropriate ventilation and often negative pressure relative to surrounding spaces, helping to prevent HD contaminants from spreading to other parts of the facility. That is why describing it as a dedicated room or area with proper ventilation that adds containment and separates HD work from non-HD spaces best captures the concept.

The other options aren’t correct because a small benchtop glove box is a primary containment device, not a secondary control; a storage cabinet with nominal ventilation doesn’t provide the necessary separation or airflow management; and a portable air purifier without room ventilation doesn’t establish the room-level containment needed to protect staff and the environment.
