A firefighter responds to emergency calls related to fires and other incidents. As a part-time firefighter, you work less than 40 hours per week on average. Some part-time firefighters perform firefighting duties during a specific, recurring shift, but you can also work on an on-call basis. In addition to responding to fires, your responsibilities include offering first aid during emergencies or performing rescue operations when necessary. A part-time firefighter takes part in their department's efforts to maintain fire trucks, hoses, and other equipment as well. You can also take steps to teach fire safety to members of the public.
