What is the minimum size of hoseline recommended for attacking a single passenger vehicle fire?

The minimum size of hoseline recommended for attacking a single passenger vehicle fire is 1 1/2 inches. This size strikes a balance between ease of handling and adequate water flow to effectively suppress the fire. In vehicle fires, the combustion can involve not only materials within the passenger compartment but also flammable fluids that may cause the fire to spread quickly. A hoseline of 1 1/2 inches allows firefighters to deliver enough volume and pressure to manage the fire effectively while still being manageable for one or two firefighters to operate.

Using a hoseline of this size helps ensure that adequate cooling of the fire and protection of nearby exposures can be achieved. Smaller lines, while easier to maneuver, may not provide the necessary volume of water required for quick suppression, especially in cases where the fire has spread or is particularly intense. Meanwhile, larger hoselines could become cumbersome and harder to control, particularly in tight spaces commonly found around vehicles. Thus, the 1 1/2-inch hoseline is optimal for this scenario, enabling firefighters to effectively combat vehicle fires.
