Which approach reflects best practice for PPE use during entry to and exit from contaminated areas?

• A. Don PPE before entering contaminated areas without guidance
• B. Rely on memory to don/doff PPE
• C. Use a one-size-fits-all approach to PPE
• D. Don and doff PPE following a zone map and established protocols

Answer: (D)

Entering and exiting contaminated areas requires a disciplined, protocol-driven approach to PPE. Following a zone map and established protocols ensures the donning and doffing happen in the correct order, in the right locations, and with the appropriate PPE for each task. This standardization minimizes the chance of self-contamination and cross-contamination by guiding you through the proper sequence, from clean areas into transition zones and the contaminated zone, and back out through a designated doffing area with hand hygiene at the proper moments. It also supports training, checklists, and a buddy system to verify steps and correct fit.

Donning PPE without guidance increases the risk of missing steps or choosing improper equipment. Relying on memory is unreliable and prone to error. A one-size-fits-all approach ignores differences in PPE types, sizes, and task requirements. Using a zone map and established protocols directly addresses these issues, making PPE use safer and more consistent.
