There are times when a firefighter's air tank may malfunction, run out of air, or sustain damage from falling debris. At times like these, it is important that firefighters be trained to help each other out. Buddy Breathing is a technique employed in a situation where one firefighter helps another who has no access to air. Firefighters learn how to share the air in one firefighter's air tank while they exit the fire scene.
