Which of the following is NOT considered personal protective equipment (PPE)?

Personal protective equipment (PPE) is designed to protect workers from various hazards they may encounter in their work environment. Gloves, safety goggles, and hard hats all serve specific functions: gloves protect the hands from cuts, chemicals, and other hazards; safety goggles shield the eyes from flying debris and chemicals; and hard hats protect the head from falling objects and impact.

A work uniform, while it can serve to identify employees and provide some level of professionalism, does not provide the same level of protective function as the other items listed. It may not be designed to guard against specific workplace hazards, which is a critical aspect of PPE. Thus, a standard work uniform is not classified as PPE, making it the correct choice in this context.
