Foam

Using Class A Foam in Wildland Firefighting enhances the effectiveness of water in suppressing wildland and interface fires. Class A foam reduces surface tension, allowing water to penetrate deeper into fuels such as brush, duff, logs, and soil. The foam creates a stable, clinging blanket that adheres to vertical and irregular surfaces, helping cool hot spots, suppress vapors, and dramatically reduce the risk of reignition.

One of the key benefits of Class A foam is its ability to knock down fire quickly. Its surfactant properties help water soak into fuels more thoroughly, leading to faster extinguishment than water alone. In addition to extinguishment, the foam provides a durable barrier that helps prevent reignition by maintaining moisture and isolating unburned fuels during mop-up operations. It also improves operational efficiency by reducing water usage and labor demands, ultimately boosting safety and effectiveness in the field. The foam's ability to cling to terrain and vegetation makes it especially valuable for wildland firefighting, where water runoff is common.

Class A foam is ideal for various applications, including direct attack on wildfires, creating wet lines, and protecting structures in wildland-urban interface zones. It's also effective on Class A structural fires, debris piles, and even industrial fires involving wood or plastic. This versatility makes it a valuable tool for wildland crews and municipal departments responding to brush and interface fires.

The foam is typically mixed at low concentrations (0.1% to 1%) and delivered using compressed air foam systems (CAFS), eductors, proportioners, or air-aspirating nozzles. The result is a lightweight, water-rich foam blanket that blankets fuels, cools embers, and acts as an insulating barrier until moisture has fully evaporated. This practical application method enhances firefighting performance, conserves resources, and extends the reach of limited water supplies.
