According to 46 CFR Part 95, which of the following statements is FALSE concerning the regulations pertaining to the carbon dioxide cylinder room for a CO2 fixed fire extinguishing system?

Correct Answer: Option C — The door must be kept unlocked.

CO2 cylinder rooms must be secured to prevent unauthorized access, as the discharge of these systems is lethal. 46 CFR requires that the door to the CO2 storage compartment be kept locked to ensure that only authorized personnel can access the controls, preventing accidental or malicious system discharge.
