What is a key aspect of personal protective equipment?

Personal protective equipment (PPE) is primarily designed to protect individuals from exposure to various hazards, particularly in health care settings where there is a risk of infection or contamination. When using PPE, healthcare workers are shielded from potential pathogens, chemicals, and other harmful substances that they may encounter during their duties. This protection is essential for maintaining safety and health, especially in environments where exposure to infectious agents is a concern.

While the other options touch on some characteristics or benefits of equipment used in clinical settings, they do not reflect the primary purpose of PPE. Improving medication delivery is unrelated to the function of PPE, as is enhancing visual clarity, which relates more to vision aids than protective gear. Although disposability can be a feature of certain types of PPE, the key aspect remains the protection it provides against hazards, making safety the central focus of using personal protective equipment.
