The carbon dioxide cylinders of a fixed fire extinguishing system may be located inside the protected space if the quantity of CO2 required to protect that space is not more than __________.

Correct Answer: Option A — 300 pounds

Per 46 CFR 95.15-5, CO2 cylinders may be located within the protected space only if the total system capacity does not exceed 300 pounds. This limitation ensures that the fire suppression agent remains accessible and effective without risking the integrity of the storage containers during a fire event.
