How often must a PEC be certified?

The primary engineering control (PEC) needs to be certified every six months to ensure that it is functioning properly and maintaining the necessary sterile environment required for compounding sterile preparations. This regular certification is crucial for patient safety and compliance with regulatory standards, as it verifies the effectiveness of the PEC in controlling contaminants and ensuring a sterile product.

While other options suggest different timeframes for recertification, six months aligns with the standards set forth by regulatory bodies, including the U.S. Pharmacopeia (USP) guidelines and state regulations, which emphasize the importance of maintaining a consistently qualified environment for sterile compounding. Regular certifications help identify any potential issues with the PEC, allowing for timely maintenance and preventing contamination risks.
