Question 378 Deck General

The correct answer is A. The space containing the cylinders for the carbon dioxide (CO2) fire extinguishing system is called the "A" class fire zone. This is a requirement specified in the US Coast Guard regulations for the design and installation of fixed fire extinguishing systems on commercial vessels. The other options, B, C, and D, do not correspond to the specific terminology used to identify the space housing the CO2 cylinders, which is correctly referred to as the "A" class fire zone.
