When exiting the building, what should SCBA users retain?

• A. A full tank
• B. Minimum air reserve
• C. No air reserve
• D. Backup oxygen supply

Answer: (B)

SCBA users should retain a minimum air reserve when exiting the building to ensure safety and allow for any unforeseen occurrences. This reserve acts as a cushion in case of delays or unexpected challenges during evacuation, such as needing to navigate through smoke, debris, or assisting a colleague. Maintaining a minimum air reserve is a critical safety practice, as it ensures that individuals have enough breathable air in case they encounter difficulties after their initial exit, allowing them to handle emergencies, communicate, or continue their exit safely. Other options, such as a full tank or no air reserve, do not consider the realities of emergency situations that may require additional air beyond what is initially thought to be sufficient during the exit.
