What’s the probable occupation of the man?

W: Hi, Tim. It’s surprising to see you in the hospital. You seem to be burnt.
M: Yeah, only a little. Nothing serious.
W: It’s serious enough for you to be in the hospital. What happened to you?
M: I had to go into a house that was on fire. There was still a little girl inside.
W: Did you get her out?
M: Yes, but I had some trouble breathing and got burnt a little when getting out of the house. So they sent me to the hospital.
W: I should say that your job is really dangerous.
M: Yeah, you may say that. But it’s all part of my job.
W: Haven’t you ever thought of giving up this job?
M: Give up? No, I love this job. Only a little injury. That’s no big deal.
W: OK. But be careful next time.
M: I see. Thank you so much.
