Firefighters must be prepared to respond immediately to a fire or any other emergency that arises. Because fighting fires is dangerous and complex, it requires organization and teamwork. At every emergency scene, firefighters perform specific duties assigned by a superior officer.
At fire scenes, they connect hose lines to hydrants, operate pumps to high-pressure hoses and position ladders to deliver water to the fire. They also rescue victims and administer emergency medical aid as needed, ventilate smoke-filled areas and attempt to salvage the contents of buildings. Their duties may change several times during one incident. Firefighters might have to stay several days on the scene in order to help immobilized survivors and bring them medical care.
Firefighters work in urban and rural areas and in industrial zones. Workers in urban and suburban areas and in industrial zones, typically use conventional firefighting equipment and tactics. Forest fires call for different methods. Other firefighters are trained to save people from freezing and rushing water.
