Which of the following is designed to protect workers from airborne drug exposure during compounding?

The Compounding Aseptic Containment Isolator (CACI) is specifically engineered to provide a controlled environment that minimizes the risk of airborne exposure to hazardous drugs for workers during compounding. It features negative pressure to contain any aerosols or dust particles, ensuring that harmful substances do not escape into the surrounding area. Additionally, CACI often includes HEPA filtration systems to further purify the air within the isolator, thereby protecting both the technician and maintaining the integrity of the compounded products.

Understanding why CACI is designed for this purpose is crucial, as it emphasizes the importance of safety protocols in compounding sterile preparations, especially when dealing with hazardous materials. The other options, while also involving airflow and contamination control, do not specifically focus on protecting workers from airborne exposure in the same way that CACI does. For instance, a Biological Safety Cabinet serves primarily to protect the working environment from biohazardous materials rather than focusing solely on compounding sterile products or hazardous drugs.
