What is one of the main purposes of engineering controls in sterile compounding?

One of the main purposes of engineering controls in sterile compounding is to protect workers from exposure to hazardous substances. Engineering controls involve the design and use of equipment and facilities that minimize risk by creating a safer environment for pharmacists and technicians who handle drugs, particularly those that are toxic or hazardous.

For instance, the use of a sterile hood or laminar flow workbench provides a physical barrier between the compounded medications and the worker, reducing the potential for inhalation or skin contact. Such controls are essential in maintaining a safe workspace and ensuring that compounding adheres to safety regulations, ultimately contributing to the health and well-being of staff in a compounding pharmacy.

While other options may relate to various aspects of drug compounding, they do not directly address the critical role that engineering controls serve in safeguarding personnel during the compounding process.
