Side jobs for firefighters?

Question

what are some good fields or jobs for firefighters to have on the side. Some sort of buisness they can run to improve income

Answer 1

Guys on my job do all sorts of things.  There are several electricians, plumbers, carpenters, painters.  

Also guys are working in meat packing, acting, restaurant work.  Anything that has some flexibility in the schedule.

Answer 2

They can have any job they want to just like any normal citizen.

I guess if they're good with the axe, they can chop wood for a living.  Since their truck can go through the traffic lights, they could be a fast delivery courier or something. :)
