Firefighter Math: 9.8 Production Rates

When planning an attack on a fire, the length and width of the line must be estimated, along with the capabilities of the hand crew(s), to determine how many crews will be needed. Generally, a 15-person crew should be able to construct a 3-foot fireline around a 1-acre grass fire in 1 hour. Below are some average ideal rates for hand crew production rates in various vegetation.

hand crew production rates

Example 1 - Patricia spots a fire burning in open prairie. She determines that the fire has a perimeter of 1,800 feet. How many hand crews should she assign to construct a 3-foot line around the fire in 1 hour?

Step 1. Look under the column for grass vegetation of the hand crew production rates chart above. Follow the column down vertically.

Step 2. Look for the row that tells how much line a crew can cut per hour. Follow the row across horizontally. Where the two lines intersect is the number of lines per hour an average crew can cut in those conditions. 
One 15-person can cut 900 ft of line per hour

Step 3. Use this information to calculate the number of hours it will take one crew to construct 1,800 feet of line.

1,800 feet of line calculation
It will take 1 crew 2 hours to cut 1,800 feet of line.
Step 4. Determine how many crews it will take to construct the line in 1 hour.

1 crew 2 hours 1800 feed of line

To cut 1,800 feet of line in 1 hour, Patricia needs to assign two crews of 15 people each.
 

When arriving at a fire scene, always assess the entire situation to determine the best way to suppress the fire.

Incident Operations Subcommittee Updates the Next Generation Position Task Book for FFT1

Date:  May 7, 2026
Questions? 
Please contact: Incident Operations Subcommittee

The NWCG Incident Operations Subcommittee (IOSC) has updated the NWCG Position Task Book for Firefighter Type 1 (Squad Boss) (FFT1), PMS 311‑14. The FFT1 Position Task Book transitioned to the Next Generation (Next Gen PTB) format in June 2025 through the Incident Performance and Training Modernization effort. Since then, IOSC has received feedback from the wildland fire community regarding coding for one of the tasks. Task #13 has been updated to include the option of evaluation in a simulation.

See IOSC Memorandum 26‑01: Transition Plan for Implementation of Updates to the NWCG Position Task Book for Firefighter Type 1 (Squad Boss) (FFT1), PMS 311‑14 for more information.

NEW! S-212, Intermediate Faller (Online) Course Available Now 

Date:  April 23, 2026
Questions? 
Please contact: Hazard Tree and Tree Felling Subcommittee

NWCG is pleased to announce that the new S‑212, Intermediate Faller (Online), course is now available on the Wildland Fire Learning Portal (WFLP). This second course in the series provides students with the knowledge and skills required to perform the duties of an Intermediate Faller (FAL2), as described in the FAL2 Incident Position Description. This course is intended for individuals seeking to advance from Basic Faller (FAL3) to FAL2.

S‑212, Intermediate Faller is a fully online, self‑paced training program consisting of 13 units. Learners will engage with interactive, scenario‑based content designed to progressively build foundational skills and knowledge essential for the FAL2 role.

Students must be qualified as a Basic Faller (FAL3) prior to enrolling in S‑212, Intermediate Faller course.

Any changes to qualification pathways will take effect with the next update of the NWCG Standards for Wildland Fire Position Qualifications, PMS 310-1, scheduled for January 2027.
