Firefighter schedules: 24/48, 48/96, Kelly and more

How common fire service schedules work, the average weekly hours of each, the special FLSA overtime rules for fire protection and practical tips for managing them.

In shortMost career fire departments in the United States use 24-hour shifts. The most common patterns are 24/48 (24 hours on, 48 off), 48/96 (two days on, four off) and Kelly schedules, which add a periodic extra day off to reduce average hours. These patterns average about 56 hours a week with three platoons. Public fire agencies can use a special FLSA overtime rule, section 7(k), which sets the overtime threshold at 212 hours in a 28-day work period instead of 40 hours a week.

Why fire departments use 24-hour shifts

Fire and emergency services need continuous coverage with crews who know each other, their equipment and their district. Long shifts reduce the number of handovers each day and give firefighters long blocks of time off, which many value highly. Stations are equipped for crews to eat, rest and sleep between calls. The trade-off is fatigue on busy shifts and long weekly hours.

Departments choose schedules based on call volume, budget, staffing, collective bargaining and the health of their crews. See our 24-hour shift schedule guide for the basics of long shifts in other industries.

Common firefighter schedules

Fire service schedules compared
Schedule Pattern Platoons Average weekly hours
24/48 24 on, 48 off, repeating 3 About 56
48/96 48 on (two 24s), 96 off 3 About 56
Kelly schedule 24 on/24 off repeated, then a longer break, with periodic Kelly days off 3 Below 56, depending on Kelly day frequency
24/72 24 on, 72 off 4 About 42
10/14 Two 10-hour days, then two 14-hour nights, then four off 4 About 42

Exact hours depend on how often Kelly days are given and how the cycle falls over each work period. Departments often adjust the pattern to fit overtime rules and budget.

The 24/48 schedule

Each firefighter works one 24-hour shift and then has two days off, so a three-platoon system covers every day. It is simple and predictable. Over a year, each firefighter works about 122 shifts, or roughly 2,920 hours, which averages 56 hours a week. The main drawbacks are frequent returns to work and limited recovery after a busy night.

The 48/96 schedule

Firefighters work two consecutive 24-hour shifts and then have four days off. Average hours are the same as 24/48, but there are half as many commutes and longer breaks. Many departments in the West adopted it to reduce commuting from lower-cost areas. Critics point to fatigue in the second 24 hours, especially in busy stations, so departments that use it often monitor call volume and allow relief when needed.

Kelly schedules

A Kelly schedule is a 24-hour pattern with additional scheduled days off, called Kelly days, built in to reduce average hours, often to manage overtime under the work period chosen by the department. A typical version works 24 on, 24 off, 24 on, 24 off, 24 on, then four days off, with a Kelly day replacing a shift at regular intervals. The term is said to come from an early Chicago official named Kelly, though accounts differ.

Overtime: the FLSA section 7(k) exemption

The Fair Labor Standards Act normally requires overtime after 40 hours in a workweek. For employees of public agencies engaged in fire protection, section 7(k) allows a work period of 7 to 28 consecutive days with a higher overtime threshold. For a 28-day work period, overtime is owed after 212 hours; shorter work periods have proportional thresholds. Public agencies with fewer than five employees in fire protection are exempt from the FLSA’s overtime requirements for those employees.

The 7(k) rules apply to public agencies. Private fire services, such as industrial or contract fire brigades, generally follow the standard 40-hour rule unless another exemption applies. Sleep and meal time on 24-hour shifts have their own rules and can sometimes be excluded by agreement. Many departments also have collective bargaining agreements that set overtime more generously than the FLSA. See FLSA overtime rules and regular rate of pay.

Recording hours accurately on 24-hour shifts

Long shifts make timekeeping more complicated, not less. A single 24-hour shift crosses midnight, may cross the boundary between two work periods and often includes holdovers when a call runs past shift change. Trades between members shift hours from one person to another, and Kelly days change the total for the period. Departments that record hours carefully, with the actual start and end of each shift, each holdover and each trade, can calculate 7(k) overtime correctly and answer questions from members quickly. Those that rely on the planned schedule alone tend to discover errors only when someone challenges a paycheck. Decide which date a shift belongs to, how holdovers are approved and how trades are recorded, and write those rules down.

Health and fatigue

Sleep disruption is one of the biggest challenges of fire service schedules. Busy stations may run calls all night, and a firefighter may then drive home or start a second job. Departments manage this by:

Managing coverage, trades and overtime

Fire departments typically allow shift trades between qualified members, and many fill vacancies through rotating overtime lists. Clear rules matter: who is eligible, how trades are approved, how hours are counted and how fairness is tracked. When trades and overtime are managed on paper or in spreadsheets, errors creep in and disputes follow. A single system for schedules, trades and time records helps. See our guide to shift bidding for ways to allocate shifts fairly.

A short example (fictional)

A suburban department with three platoons on a 24/48 schedule finds that one station runs calls through most nights while two others are quiet. Firefighters at the busy station report fatigue and use more sick leave. The department adds a peak-hour unit at the busy station from noon to midnight and rotates crews between stations each quarter. Overtime falls slightly, and sick leave at the busy station returns to the department average.

How EZTime helps

EZTime supports 24-hour shifts and repeating platoon patterns, records clock-ins from a station kiosk or the mobile app, and lets members request trades through shift swaps with approval. Overtime rules can be configured to match your work period, and reports show hours by member and period. Confirm your overtime configuration with your payroll and legal advisers.

Frequently asked questions

What is the most common firefighter schedule?

The 24/48 schedule is very common, along with 48/96 and Kelly schedules.

How many hours a week do firefighters work?

Three-platoon 24-hour schedules average about 56 hours a week; four-platoon schedules average about 42.

When do firefighters get overtime?

Public fire agencies can use FLSA section 7(k): for a 28-day work period, overtime is owed after 212 hours. Contracts often provide more.

What is a Kelly day?

An extra scheduled day off built into a 24-hour rotation to reduce average hours.

Is a 48/96 schedule safe?

It depends on call volume. Busy stations may see fatigue in the second 24 hours; departments often monitor and adjust.

Do private fire brigades use 7(k)?

Generally no. Section 7(k) applies to public agencies; private employers usually follow the standard 40-hour rule.
