How should PPE doffing be conducted to minimize contamination?

• A. In any open area after entry.
• B. By bagging PPE at the end of the day.
• C. In a controlled doffing area with stepwise removal, hand hygiene, and proper disposal or decontamination of PPE.
• D. In a single-step removal in a contaminated zone.

Answer: (C)

Minimizing contamination during PPE doffing requires a controlled area and a careful, stepwise removal process with hand hygiene and proper disposal or decontamination of the equipment. A designated doffing space helps contain any residual contaminants and provides the right supplies and supervision to ensure each item is removed in a way that limits contact with contaminated surfaces. Removing PPE in a specific order and performing hand hygiene between steps reduces the chance that contaminants transfer to skin, mucous membranes, or clean surfaces. Proper disposal or decontamination of each piece prevents reintroduction of contaminants into the environment or to others.

Removing PPE in an open area increases the risk that contaminants spread to the surroundings or to people. Bagging PPE only at the end of the day delays critical decontamination and can lead to cross-contamination if the bag or its contents contact clean surfaces. Doffing in a single step within a contaminated zone bypasses the stopping points that help prevent contamination, making it far more likely for contaminants to reach skin, eyes, or the airway.
