Question 774 Deck Safety

The correct answer is A) The door must be kept unlocked. This is correct because the regulations for fixed CO2 fire extinguishing systems require that the cylinder room door be kept locked to prevent unauthorized access. This is to ensure the system is not tampered with or accidentally discharged. The other statements (B, C, D) are all true requirements for the cylinder room as per the applicable regulations. The other options are incorrect because: B) The temperature limit is 130°F, C) The compartment must be clearly marked, and D) Proper ventilation is required to prevent the buildup of CO2 gas.
