There is no one way to say "fire fighter." Among the options are, of course, qul SuvwI' "fire fighter, fire warrior," but also qul qaDwI' "fire challenger" and (though less frequent) qul tlhay'moHwI' "fire tamer." It's also possible to say qul QongmoHwI' "one who puts fires to sleep," but that's usually not applied until the fire is actually out.
