On a diesel powered vessel with fixed CO2 system, how many portable extinguishers are required in the propulsion machinery space?

• A. NONE
• B. ONE
• C. TWO
• D. THREE

Answer: (A)

A fixed fire suppression system in the propulsion machinery space changes what is needed inside that space. When a diesel-powered vessel has a fixed CO2 system, the space is considered protected by that automatic flooding system, which eliminates the requirement for portable extinguishers there. The CO2 system is designed to suppress typical machinery-space fires without needing hand-portable units in that same space. You would still follow regulations for extinguishers in other areas of the vessel, but inside the propulsion machinery space itself, none are required.
