Firefighters or superheroes ?

The firefighters  were capable of saving people, they had the ability to stop fires and
they were able to progress into toxic smoke with their gaz masks.
Contrary to superheroes like superman or spider man, they weren't able to fly or
they had not the ability to walk on the walls whereas they had a good phisycal condition and
they saved a lot of people !
That's why to my mind they are superheroes !
