The main idea here is identifying which standard governs foam systems across all expansion types. NFPA 11 is the standard that specifically covers foam-fire protection systems, detailing how to choose and install foam concentrates, proportioning equipment, and related hardware to produce foam with low, medium, or high expansion. It lays out requirements for system design, installation, testing, and maintenance so that the foam blankets form properly and cover the fire effectively, no matter the expansion type being used. Because it directly addresses all three expansion methods and the equipment and procedures needed to achieve them, it is the best answer. The other standards focus on different aspects of fire protection (such as general water-based systems, maintenance, or other specific applications) and do not provide the same comprehensive guidance on foam expansion systems.
