Which firefighting method is used to achieve greater reach with water application?

The solid stream method of firefighting is used to achieve greater reach with water application because it produces a concentrated, high-velocity jet of water. This allows the water to travel further distances compared to other methods. Solid streams minimize the amount of water that is broken into droplets, allowing for less water loss to evaporation and greater penetration of heat and smoke, which is particularly useful in attacking fires from a distance or targeting high locations. The focus of a solid stream is to maintain a tight, powerful stream that can reach the seat of the fire effectively.

Other methods, such as fog streams, create a mist that can be beneficial for reducing heat and improving visibility, but they generally do not reach as far and tend to disperse water over a wider area. Wet water application involves the addition of agents to water to enhance its effectiveness, which is not primarily focused on reach. Splash stream, which may refer to a less controlled application of water, would also lack the direct reach and focused application that solid streams provide. Hence, solid streams are preferred for situations where distance and penetration are critical.
