Which of the following is NOT a type of PPE?

The correct choice identifies a valet cart as not being a type of personal protective equipment (PPE). Personal protective equipment encompasses items specifically designed to protect individuals from hazards in their environment, particularly in workplace settings.

Examples of PPE include reusable ear plugs, which safeguard hearing from excessive noise; carbo flex plugs, which serve a similar auditory protection function; and face shields, which protect the face from chemical splashes, flying objects, or infectious materials.

In contrast, a valet cart is a piece of equipment used for transporting items, typically in a hospitality or service setting, and does not serve the purpose of protecting an individual's physical safety or health in the same way that PPE does. Therefore, recognizing the role and definition of PPE makes it clear why the valet cart does not fit within that category.
