We always approach a vehicle fire from the sides. What do you do when the fire is contained inside a closed trunk or engine compartment? Forcing the hood would put a firefighter in front of the bumper. You could use the K12 to cut on opening in the hood. But here is some food for thought. Have the nozzle man (or woman) angle the attack line water stream at the ground directly underneath the fire and deflect the water up into the compartment. Then, if the fire is still relatively small that take a halligan tool and pry out the headlight lens and housing. This may not work on every vehicle, but it should at least provide a hole that you can get more water into a compartment fire. Flood the compartment through this access point and nobody has to leave the side of the vehicle to fight the fire.
