Which item is listed as part of SAME DAY use environment controls?

• A. Gloves are not required
• B. No partitioning of space
• C. Buffer zone clearly identified
• D. Drafts allowed

Answer: (C)

Same-day use environment controls rely on a clearly identified buffer zone to keep the preparation area separate from the surrounding, less-controlled spaces. This clearly marked boundary helps manage airflow, reduce contamination risk, and tell staff exactly where to perform handling and compounding activities. The buffer zone acts as a controlled transitional space so that any activities related to same-day use stay within a defined, protected area.

Gloves are required, and space should be partitioned to maintain separation between clean and less-clean areas; drafts should be minimized because they can carry particulates.
