Which group does NOT need to wear N95 masks according to the provided procedures?

The group that does not need to wear N95 masks according to the provided procedures is non-patient care providers in the apparatus. This distinction is based on the risk exposure associated with their roles compared to other groups involved in direct patient interactions or scenarios where airborne transmission of pathogens may occur.

Fire chiefs, aerial operators, and medical responders are often in positions where they could be exposed to hazardous environments or infectious diseases that necessitate the use of personal protective equipment, such as N95 masks. On the other hand, non-patient care providers in the apparatus typically do not engage in activities that would put them at significant risk of airborne transmission, as their duties are usually supportive in nature rather than direct care. Consequently, this specific group is exempted from the requirement to wear N95 masks, enabling them to perform their functions without the need for such protective equipment.
