FAQ: Foam Fire Suppression Systems

Foam fire suppression systems protect some of the most hazardous environments out there. Though, this is a less common protection system, it requires a highly trained technical staff to inspect and maintain. Here are some common questions we get regarding foam systems.


What is a foam system

Foam is a stable mass of small, air-filled bubbles with a lower density than oil, gasoline, or water. A foam system solution is made up of three ingredients: water, a foam concentrate, and air. Water is mixed with the proportioned foam concentrate to form a foam solution. This solution is then mixed with aspirated air to produce a foam which readily flows over fuel surfaces.


Who needs a foam system?

Foam systems typically cover are with flammable liquid storage, loading racks, processing areas, refineries, dike areas, aircraft hangars, heliports, engine test facilities, marine applications, and warehouses.


How does a foam system work?

Foam systems suppress fire by separating the fuel from the air.


How often should I inspect my foam system?

Foam systems require semi-annual inspections by qualified technicians.
