Can the oxygen level be controlled within the shelter's atmosphere?

• A. Yes
• B. No
• C. Sometimes
• D. Not sure

Answer: (A)

Yes—the oxygen level can be controlled within the shelter's atmosphere. Shelters are equipped with air systems and monitoring that manage breathing air, so oxygen can be added or the air exchanged to keep O2 in a safe range. Sensors continually check oxygen and carbon dioxide levels, and adjustments to ventilation or supplemental oxygen are made as needed to maintain a breathable environment. This controlled design means occupants aren’t relying on chance; the atmosphere is kept within safe limits.
