Which of the following statements is true concerning Halon 1301 fire extinguishing equipment?

Correct Answer: Option D — For portable extinguishers, the agent is only available in a 2 pound unit.

Halon 1301 is a clean, gaseous extinguishing agent that leaves no residue, making it ideal for electrical fires. Portable units are typically limited to small capacities, such as 2-pound units, due to the agent's high vapor pressure and the specific design requirements for handheld discharge nozzles in marine environments.
