What is the purpose of using personal protective equipment (PPE) in emergency situations?

The primary purpose of using personal protective equipment (PPE) in emergency situations is to safeguard the first responder from exposure to bloodborne pathogens and other infectious materials. This protective gear forms a barrier against potential hazards that can be present in the environment, such as bodily fluids or airborne pathogens. By utilizing PPE, responders minimize the risk of infection and ensure their health and safety while providing care to patients in potentially dangerous conditions.

While other options mentioned may have valid points in different contexts—such as providing warmth or aiding in visibility—the fundamental role of PPE remains focused on protection against health risks, which is critical for maintaining the responder's ability to help others while remaining safe themselves.
