Final answer:
Engineering controls are essential in nonsterile HD compounding to minimize exposure to hazardous drugs and ensure worker safety.
Step-by-step explanation:
Engineering controls play a crucial role in ensuring the safety of nonsterile HD (hazardous drug) compounding in both the C-PEC (containment primary engineering control) and C-SEC (containment secondary engineering control) areas. These controls help to minimize exposure to hazardous drugs and protect the health and safety of workers. An example of an engineering control requirement for C-PEC is the use of a ventilated cabinet or a compounding aseptic containment isolator (CACI) that provides a contained environment for the compounding of hazardous drugs. In C-SEC, engineering control requirements might include proper air handling and filtration systems to maintain a negative pressure and prevent the release of hazardous drug particles into the surrounding area. Overall, engineering controls are designed to prevent or minimize exposure to hazardous drugs by creating barriers, controlling airflow, and maintaining containment during the compounding process.
