The recommended order for donning personal protective equipment (PPE) is important for ensuring proper infection control and minimizing the risk of cross-contamination. Starting with the gown allows for a barrier against contaminants, and properly securing it first ensures that it provides adequate protection throughout the process. Next, putting on a mask is essential for protecting the respiratory system from aerosols and droplets. After the mask is donned, goggles are added to protect the eyes from splashes and potential exposure to infectious materials. Finally, gloves are put on last since they are the primary defense against contact with contaminated surfaces and bodily fluids. This sequence ensures a comprehensive protection layer while minimizing the risk of touching contaminated areas after PPE is applied, thus maintaining effective infection control practices. This order emphasizes the necessity of sequential layering where the outermost PPE is added last to protect the inner layers and yourself from exposure.
