Which gaseous system has the lowest capacity for leakage?

Explanation:
A clean agent system is designed for tight containment with minimal gas loss. These systems use sealed, purpose-built cylinders and carefully engineered, low-leakage piping and fittings. The emphasis on robust seals, precise discharge hardware, and regular leak testing keeps any unintended gas escape to an absolute minimum, so the system has the lowest capacity for leakage among the options. In contrast, CO2 systems often involve large volumes and more pathways for potential leakage, and older halon systems can have more leak points due to aging components and broader piping runs. Nonfluorinated agents can be part of clean-agent designs too, but the overall attachment to tight, well-sealed containment typically yields the least leakage.
