Fire stream types are generally classified as which three categories?

• A. Solid, Fog, and Broken
• B. Liquid, Gas, and Solid
• C. Jet, Spray, and Mist
• D. Narrow, Wide, and Straight

Answer: (A)

Fire stream types are described by how water exits the nozzle, producing three broad patterns: solid stream, broken stream, and fog stream. A solid stream is a tight, cohesive jet that travels a long distance with concentrated energy, useful for reaching flames from afar and for knockdown, but it provides less cooling at the far end and can be harsher in close quarters. A fog stream disperses water into a wide cloud of fine droplets, delivering rapid cooling and protecting firefighters as you move through hot environments, though it has shorter reach and can reduce visibility. A broken stream sits between the two, delivering multiple discrete streams to increase cooling and surface area while maintaining more control and better reach than a pure fog pattern. These three patterns are the standard classifications used in interior attack practice. Other groupings describe states of matter or specific nozzle settings rather than the overall stream patterns used for fire suppression.
