what is necesary for me to become a fire fighter

Hi,
I found this online for you on the BLS/Bureau of Labor Statistics website:
Requirements for entry-level firefighters vary by jurisdiction. Firefighters need at least a high school diploma or the equivalent. They also may need to have completed postsecondary education in order to attain various certifications before being hired, such as the Emergency Medical Technician (EMT)-Basic certification. Most firefighters also must pass a written and physical test and complete a series of interviews. Firefighters receive extensive training after being hired.
I would suggest visiting a local fire dept station and talking to the firefighters...they are usually willing to give you career advice and show you around. If you are old enough, you can sometimes volunteer as a Firefighter as well. If you are interested in the military, the Navy trains every Sailor in firefighting as part of their job. Good luck!
