If you have a serious interest in becoming a firefighter. Check into the guidelines at Landrum Area Fire and Rescue. Although they have paid positions they also have volunteer positions. Volunteering will give you the opportunity to see what being a firefighter is like and if you really want to do it as a career.
When we're not putting out fires, or practicing putting them out, another thing we do is prevent the fires from starting in the first-place! We go to local businesses and look for dangerous things like exposed wires and blocked emergency exits, we go into people's homes and replace smoke detector batteries, and go to schools and community centers to teach people of all ages about fire safety.
Because firefighters are on-call 24-hours a day, 7-days a week, 365-days a year, we usually live in our fire stations, working shifts as long as 48-hours straight! That means we have to do all the same chores you do at home, like vacuuming, cooking, doing dishes, folding laundry, etc.
Those things are pretty universal to every firefighter no matter where you go in the world. There are some differences depending where you go though. For example, in many parts of the United States, firefighters are also trained as Emergency Medical Technicians or Paramedics, and respond to medical emergencies with the ambulance.
I hope that helps! Let me know if you have more questions about firefighting!
