According to Coast Guard Regulations (46 CFR), which of the following statements is true concerning fixed carbon dioxide fire extinguishing systems?

Correct Answer: Option D — The cylinders may be located within the space protected provided the system consists of not more than 300 pounds (136.1 kg) of carbon dioxide.

46 CFR 95.15-5(c) explicitly permits the installation of CO2 cylinders within the protected space provided the total quantity of CO2 does not exceed 300 pounds. This regulation balances the need for compact system design with safety requirements to ensure the extinguishing agent is not compromised by the fire.
