What is the primary safety reason for using a containment device during chemo compounding?

• A. To improve odor control.
• B. To prevent exposure to staff and environment by containing aerosols and spills during preparation.
• C. To reduce costs.
• D. To speed up preparation.

Answer: (B)

The main safety principle here is protecting people and the environment from hazardous chemotherapy drugs by preventing aerosol release and spills during preparation. Chemotherapy manipulations can generate airborne particles and surface contamination; a containment device creates a controlled, often negative-pressure, work area with filtration that captures drug particles and prevents them from escaping into the room or being absorbed by staff. This setup directly reduces inhalation, dermal exposure, and environmental contamination, which is the core reason for using containment during compounding. Odor control, cost savings, or speeding up prep don’t address the actual exposure risk or environmental spread as effectively.
