In SCBA terminology, what does "Buddy breathing" refer to?

"Buddy breathing" refers to the practice of sharing an air supply between users, which is a vital technique in emergency situations involving self-contained breathing apparatus. When two individuals, typically both wearing SCBAs, find themselves in a situation where one has a depleted air supply or experiences a malfunction, they can connect their equipment to share breathable air. This process enhances safety and survival chances when facing hazardous environments, such as during firefighting or rescue operations.

The concept emphasizes teamwork and communication, ensuring that each person remains aware of their partner's status while managing air resources effectively. In scenarios where immediate exit from a dangerous atmosphere is not possible, buddy breathing serves as a crucial life-saving skill. By understanding this terminology, SCBA users are better equipped to handle emergencies that require close coordination and support.
