The DRS5600 Mobile Foam Unit is specifically engineered for high-risk fires involving flammable liquids, fuels, and hazardous substances that require foam-based suppression. Due to their higher density compared to standard liquids, foams act as a protective blanket over flames, creating a film layer that effectively isolates the fire from oxygen. While designed for use by trained fire safety personnel, its mobile structure allows it to be easily deployed to areas with water sources such as hydrants or fire department connections.
