Junior firefighting is a youth activity in participating fire departments (usually Volunteer Stations.) throughout the United States, and also in the UK, through the YFA - Young Firefighter Association. The junior fire service has many names, such as Junior Fire Corps, Cadet Firefighting, or Explorer Scouts in the United States. Junior firefighters are usually 14 to 17 years old and are not permitted to enter any dangerous situation unless specified by state laws or have a certain amount of training hours in. Junior firefighters work as a support unit of a fire department.
