Question 770 Deck Safety

The correct answer is A) 300 pounds. According to the regulations for fixed fire extinguishing systems, the carbon dioxide (CO2) cylinders may be located inside the protected space if the quantity of CO2 required to protect that space is not more than 300 pounds. This is to ensure that the CO2 discharge does not create an overpressure or potential explosion hazard within the protected space. The other options, B) 400 pounds, C) 500 pounds, and D) 600 pounds, are incorrect because they exceed the 300-pound limit specified in the regulations for locating the CO2 cylinders inside the protected space.
