How Long Is a Firefighter Shift?

The unique demands of emergency response require a scheduling structure unlike a conventional 40-hour work week. Firefighter scheduling is designed for constant operational readiness, ensuring trained personnel are always available to respond instantaneously. This necessity for 24/7 coverage leads to extended shifts and complex rotations that balance job demands with crew rest and recovery.

The Standard Firefighter Shift Schedule

The most prevalent scheduling model for career firefighters in the United States is the 24-hours-on, 48-hours-off system, commonly referred to as the 24/48 schedule. Under this rotation, a firefighter works a continuous 24-hour shift and is then off duty for the subsequent 48 hours. This system divides personnel into three rotating shifts (A, B, and C) to ensure continuous coverage.

This three-day cycle means a firefighter works two 24-hour shifts over a six-day period. The rotation continues seamlessly, ensuring a fully staffed crew is always on duty, including weekends and holidays. Averaged over a longer period, this schedule results in firefighters working an average of 56 hours per week. Departments often use a rotating day off, sometimes called a “Kelly Day,” within the cycle to reduce total hours worked and maintain compliance with federal labor standards for overtime.

Why Firefighters Work Long Shifts

The 24-hour shift model is maintained for operational effectiveness and cost management. Long shifts minimize the frequency of shift changes, reducing administrative overhead related to payroll and personnel management. Fewer shift handovers also mean less disruption to the daily routine and reduce the chance of miscommunication between incoming and outgoing crews.

Having personnel on duty for a full day promotes crew cohesion. Extended time spent together allows crews to build trust and familiarity, which is essential for effective teamwork during high-stress emergency incidents. The 24-hour period allows crews to complete a full cycle of station duties, physical training, and continuing education efficiently. This ensures crews are fully trained and prepared for any call.

Variations in Shift Schedules by Department Type

Not all fire departments utilize the 24/48 rotation; the optimal schedule depends on factors like department size, call volume, and local funding. Some departments, particularly in larger metropolitan areas with high call volumes, use shorter shifts (8 or 12 hours) to reduce fatigue. Conversely, other departments adopt schedules that increase time off between shifts to improve firefighter well-being and recruitment.

24/72 or 48/96 Schedules

Some departments use models that provide longer recovery time between shifts. The 24-hours-on, 72-hours-off (24/72) schedule, for example, reduces a firefighter’s average workweek from 56 to approximately 42 hours. The 48-hours-on, 96-hours-off (48/96) model involves working two consecutive 24-hour shifts, followed by four full days off. These longer off-periods are favored because they allow for more personal time and help mitigate long-term fatigue.

10/14 Schedules

The 10/14 schedule is another alternative, often used in a rotating system. This model involves two 10-hour day shifts followed by two 14-hour night shifts, then a set block of days off. This system maintains 24-hour coverage while reducing the length of any single shift. Reducing shift length can lead to less fatigue compared to a full 24-hour tour.

Volunteer and Paid-on-Call Structures

Scheduling for volunteer and paid-on-call personnel differs significantly from career departments. These individuals respond to emergencies from home or their primary employment. They are compensated on a per-call basis or receive a small stipend, rather than a fixed salary. Volunteer departments generally do not have fixed, regularly staffed shifts, relying instead on personnel to be ready to respond when needed.

The Reality of the 24-Hour Shift

The 24-hour shift is a structured day, not a period of constant emergency response. The shift begins with an apparatus check to ensure all vehicles and equipment are ready for immediate deployment. Morning hours are dedicated to station chores, such as cleaning the firehouse and washing the trucks, as the crew is responsible for maintaining their workspace.

The afternoon is often the busiest period for non-emergency activities, including physical training, continuing education, and mandatory drills. Crews pool money to buy and prepare meals together, which strengthens team cohesion. Although there is designated time for sleep or rest, usually after 10:00 PM, the crew must be ready to respond instantly to an alarm. Rest periods are frequently interrupted by calls, making sound sleep a challenge.

Managing Fatigue and Work-Life Balance

The extended hours and fragmented sleep inherent in the 24-hour shift challenge a firefighter’s physical and mental well-being. Sleep deprivation and disrupted circadian rhythms can lead to exhaustion, increased stress, and health issues. Fatigue impairs cognitive function and reaction time, which directly impacts safety and decision-making on the fireground.

To counteract these effects, departments and individual firefighters employ strategies to manage shift work consequences. Firefighters prioritize self-care, including regular exercise and stress-reduction techniques, to maintain mental health. Coordinating schedules with family and friends and actively disconnecting from work during time off are essential for a healthy work-life balance. Departments are also recognizing the need for adequate sleep accommodations and resources to support rest and recovery.

Mandatory Overtime and Holdovers

Mandatory overtime, or “holdovers,” are common exceptions to the standard shift schedule. Holdovers require a crew to remain on duty past the planned 24-hour mark. They are typically triggered by staffing shortages, large-scale emergencies, or when a crew is actively engaged in an incident that runs past the scheduled end of their shift.

This forced extension can significantly lengthen the work period, sometimes resulting in personnel working 48 or even 72 consecutive hours. Mandatory overtime is a source of stress and burnout, as it exacerbates fatigue and disrupts recovery time. While departments strive to fill vacancies voluntarily, the need to maintain minimum staffing levels means forced overtime is necessary to ensure continuous emergency coverage.
