Who is included in the PAR process?

The correct choice identifies all personnel assigned or in the care of the EMS unit as included in the PAR (Personnel Accountability Report) process. This is crucial because the PAR process is designed to ensure that every member of the emergency scene is accounted for, enhancing safety and operational effectiveness.

Including all personnel means that anyone actively engaged or responsible for patient care, regardless of their specific role or training level—whether they are EMTs, paramedics, or other support staff—must be part of this accountability check. It reflects a collective responsibility to safeguard the wellbeing of both patients and responders during emergency operations.

The other options focus on specific groups, which would not provide a complete picture of accountability. For instance, limiting it to only patients in transport neglects the broader team dynamics, and restricting it to trained EMTs and paramedics excludes other essential personnel who play supportive roles. Similarly, while law enforcement officers may be present and play an important role at the scene, they are not always part of the EMS unit's internal accountability processes, hence would not be included in the PAR.
