In an IDLH atmosphere, buddy breathing is:

• A. A method used for emergency escapes
• B. Acceptable and should be implemented immediately
• C. Required to be initiated by the RIC
• D. Unsafe unless performed by trained personnel

Answer: (A)

In an IDLH atmosphere, buddy breathing is a last-resort technique used to get a firefighter to safety when their own air supply or route to safety is compromised. It involves one firefighter sharing air with a endangered partner so the distressed person can continue to breathe while moving toward a known exit. This is not routine or automatic—it's an emergency option that requires quick, coordinated action, clear communication, and a preplanned approach. It also depends on trained responders who understand how to manage the regulator exchange safely and monitor air supplies throughout the escape. So the idea is that buddy breathing serves as an emergency escape method, used only when no other means of getting out safely are available.
