Which piece of personal protective equipment is considered the last item to be removed?

The mask is considered the last item to be removed because it serves as an essential barrier to protect the respiratory system from potential exposure to infectious agents, particularly in clinical settings where aerosol-generating procedures may occur. Removing the mask last ensures that the clinician or healthcare worker maintains a protective barrier until all other potential contaminants have been dealt with, thus minimizing the risk of inhaling pathogens.

In addition, while other items of personal protective equipment like gowns, gloves, and shoe covers are also important for preventing contamination, the mask plays a critical role in safeguarding the operator's respiratory tract, especially after handling potentially infectious materials. This protocol helps maintain a higher level of safety and infection control, particularly in endoscopic procedures that may involve exposure to blood and other bodily fluids.
