What should a firefighter do if they encounter an injured person at a scene?

The most appropriate action for a firefighter encountering an injured person at a scene is to provide first aid if trained and call for medical assistance promptly. This response is crucial because firefighters often operate in emergency situations where quick intervention can save lives. Being trained in first aid allows them to assess the injuries and provide immediate care, which is vital while waiting for professional medical personnel to arrive.

It is essential for firefighters to balance their duties of tackling the fire while also ensuring that any injured individuals receive the necessary help. Providing first aid can stabilize the person's condition, potentially preventing further injury or complications.

In contrast, ignoring the injury to focus solely on the fire would disregard the responsibility to protect life, which is a primary duty of a firefighter. Waiting for medical personnel to arrive without taking any action may lead to worse outcomes, as the injured person may require immediate assistance that can only be provided by someone on the scene. Carrying the person to safety without assistance could risk both the firefighter's safety and the injured person's well-being, especially if done improperly or without assessing the extent of the injuries.
