How often should PEC cleaning be performed?

The correct answer is that PEC (Primary Engineering Control) cleaning should be performed every shift. This practice is crucial for maintaining a sterile environment within the compounding area. Regular cleaning helps to remove any potential contaminants, such as dust, microbial life, and any residue that may accumulate during compounding activities.

By cleaning every shift, it ensures that the PEC is consistently maintained in a state conducive to safe sterile compounding. This frequency accounts for the various activities that take place in the compounding area, ensuring that the risk of contamination is minimized throughout the working day. Maintaining such rigorous cleaning schedules is a critical component of infection control and assures the integrity of sterile pharmaceutical preparations.

Other options may suggest less frequent cleaning, which could lead to an increased risk of contamination and compromise patient safety. Therefore, the practice of cleaning every shift aligns with the stringent guidelines necessary for sterile compounding environments.
