Part 2/7:
Foam fire retardant systems are an essential safety feature in modern hangars due to the presence of large aircraft, which often contain significant fuel reserves. In the event of a fuel or oil spill, a fire could ignite rapidly, creating a hazardous environment that is difficult for firefighters to access quickly. The foam system is designed to create a barrier that can extinguish flames and absorb spills, ideally within 30 seconds of activation.
Types of Fire Retardant Foams
There are two main types of foams utilized in fire retardant systems: synthetic foams and protein-based foams.
