Those who fight fires are trained to do their job anywhere – from forests to rural areas to urban high-rises. Firefighters work first and foremost to protect lives, and then they turn their attention to protecting property. Some firefighters choose to work their way up the ladder, so to speak, starting with volunteer work at their local firehouse, coupled with their high school diploma. Those who want to advance up the ranks faster can turn to a fire science degree that will prepare them for responsibilities at the state or federal level. Understanding different types of firefighting careers and what each entails is the first step to choosing the right path.

Firefighters show up at the scene of a fire or emergency and rely on advanced tools and equipment to handle the situation. That's a very broad overview; now let's get down to the details.

Firefighters receive expert training that prepares them to handle a variety of emergency situations. Though fighting fires are what they are best known for (as the name implies), firefighters also handle medical emergencies, rescuing and treating the injured, educating the public and more. Their work often requires them to be on call at all hours; some respond to calls from their private homes, while others stay in the firehouse during their shifts in order to respond to calls much faster, especially in urban areas.
