Part 3/7:
Synthetic Foams are known for their rapid expansion and quick response times. While they are highly effective at extinguishing fires, these foams pose a significant environmental hazard. When they escape into the ground, they can contaminate water supplies and ecosystems, often leading to long-term restrictions on local resources.
Protein-Based Foams are deemed more environmentally friendly, as they are biodegradable. Although they do not expand as quickly as synthetic foams, they provide greater heat resistance and durability against larger fires. This makes them a preferred choice in new hangars, as regulatory bodies discourage the use of synthetic foams for future installations.
