AI Explanation
The correct answer is A) It has a portable hose and nozzle. A semi-portable CO2 system is characterized by having a portable hose and nozzle that can be used to direct the CO2 agent to the fire. This allows the system to be moved around as needed, in contrast to a fixed, permanently installed CO2 system. The other options are incorrect - B) the cylinders are typically mounted vertically, not horizontally, C) the distribution piping is not permanently installed, and D) there is no weight limit of 50 pounds per cylinder for a semi-portable system.
