TUCSON, Ariz. (13 News) – The Tucson Fire Department has new life-saving equipment that will greatly improve crews’ response to emergencies. The new air, power, and light truck is the only one of its kind in Tucson. The easiest way to describe it is as an all-in-one truck that can do just about anything firefighters may need on-site. It can light up a scene, refill air tanks, and, during the hot summer, give fire crews a place to cool down.
