Which of the following is not a type of personal protective equipment (PPE) that should be used by an officer?

The standard uniform is not classified as personal protective equipment (PPE). PPE is specifically designed to protect the wearer from hazards that could cause injury or illness, particularly in situations involving exposure to chemical, biological, radiological, or physical hazards.

Mouthpieces, protective body clothing, and resuscitation bags are all designed with safety in mind. Mouthpieces protect the officer from bites or other injuries during physical altercations. Protective body clothing, such as bulletproof vests, shields an officer from firearms or sharp objects. Resuscitation bags are crucial for providing emergency medical assistance, ensuring that an officer can perform necessary life-saving measures without risking their health.

In contrast, while a standard uniform may serve to identify officers and foster professionalism, it lacks the specific protective features that define PPE. Therefore, it is categorized differently, which solidifies the rationale behind this choice.
