What is the main purpose of environmental wipe sampling?

The main purpose of environmental wipe sampling is to verify the effectiveness of containment strategies used when handling hazardous drugs (HDs). This sampling method provides a quantitative measure of the contamination levels of these substances within the pharmacy or healthcare setting. By analyzing wipe samples from surfaces that might have come into contact with HDs, facilities can assess whether their engineering controls, such as fume hoods and closed-system drug transfer devices, are functioning effectively in preventing contamination. Additionally, the results can indicate whether cleaning procedures are adequate and being followed correctly, which contributes to maintaining a safe environment for both employees and patients.

While other choices touch on important aspects of hazardous drug management, this option uniquely emphasizes the importance of evaluating the effectiveness of current controls and practices, which is paramount in ensuring safety.
