Engine or Wagon
An engine or wagon is a fire apparatus that has a pump, a tank and water hose. On fire incidents, the crew is responsible for ensuring an adequate supply of water is available and for actually extinguishing the fire. Every engine and wagon is equipped with basic life support equipment for emergency medical incidents including a defibrillator to shock a cardiac arrest patient. All personnel on career-staffed engines or wagons are Emergency Medical Technicians at a minimum. An engine company in Prince William County is comprised of two units -- an engine and wagon. Normally only one unit is staffed at a time.
