What is the correct procedure when a member must leave a structure to change an air cylinder?

• A. The member exits alone if he or she can do so safely
• B. The member and his or her appointed buddy exit
• C. All company members exit together
• D. Those members who are low on air exit together

Answer: (C)

When a firefighter must leave to change an air cylinder, the safest course is to have the entire company exit together. This keeps the team intact and ensures everyone outside can be accounted for and coordinated before any change is made. Exiting as a group avoids leaving interior teammates without a buddy or without clear supervision, which helps maintain the two-in, two-out safety principle and prevents confusion about who is inside or out. Once outside, the cylinder change can be performed in a controlled, secure way, and the crew can re-enter in an organized manner with everyone accounted for. Leaving only some members out or targeting a subset to exit can create gaps in accountability and increase risk if conditions inside worsen or a rescue becomes necessary.
