Question 286Safety & Environmental - Assistant Engineer

The correct answer is A) 300 pounds. According to the regulations governing fixed fire extinguishing systems, the carbon dioxide (CO2) cylinders of a fixed fire extinguishing system 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 specified in the relevant standards and regulations for these types of systems. The other options are incorrect because they exceed the 300-pound limit set by the regulations for locating the CO2 cylinders within the protected space. Placing the cylinders inside the space they are intended to protect can pose safety risks if the quantity of CO2 is too large.
