Class A fires typically require low expansion foam, which effectively smothers the flames. For a direct attack, low expansion foam is still the best choice due to its ability to penetrate and extinguish the fire promptly. Other foam types are more appropriate for different situations and are not ideal for directly combating Class A fires.
