Firefighters have demanding jobs that require dedication. They are on call 24/7 and spend their downtime cleaning equipment, studying techniques, and learning about new technology. While the job looks undemanding from the outside, firefighters are constantly training. The fire chief says it is difficult to find enough dedicated applicants who can pass the physical and mental tests. Firefighters work 24-hour shifts and may be called in on their days off. Though dangerous, they find the work rewarding for helping people.
