Downhill Fireline Construction Checklist

 

9. Building fireline downhill with fire below. Three firefighters use tools to dig fireline down a steep slope covered in grass and brush. Large flames are below them as the fire burns uphill.

9. Building fireline downhill with fire below.

Building fireline downhill requires special attention to safety factors because of the potential for rapid uphill fire spread. This Watch Out depicts firefighters building fireline downhill without first mitigating the existing hazards.

Read about all 18 Watch Out Situations..

Downhill fireline construction is hazardous in steep terrain, fast-burning fuels, or rapidly changing weather. Downhill fireline construction should not be attempted unless there is no tactical alternative. When building downhill fireline:

  • Crew supervisor(s) and fireline overhead must discuss assignments prior to committing personnel. Qualified, responsible overhead individuals such as a Task Force Leader (TFLD) or an Incident Commander Type 4 (ICT4) at minimum, will stay with resources until the job is completed.
  • Decisions about downhill fireline construction will be made only after proposed fireline has been scouted by supervisor(s) of involved crew(s).
  • Lookouts, Communications, Escape Routes, and Safety Zones (LCES) will be coordinated for all personnel involved. This includes verifying:
    • Crew supervisors are in direct contact with lookout(s) who can see the fire.
    • Communication is established between crews.
    • Rapid access to safety zones is ensured in case fire crosses below crews.
  • Direct attack will be used whenever possible; if not possible, the fireline should be completed between anchor points before being fired out.
  • Fireline will not lie in or adjacent to a chute or chimney.
  • Starting point will be anchored for crews building fireline down from the top.
  • Bottom of the fire will be monitored; if the potential exists for the fire to spread, action will be taken to secure the fire edge.
  • Before carrying fire with you, ensure it can be done safely.

NWCG Standards for Rapid Extraction Module Support, PMS 552

Date: July 10, 2024
Contact: Incident Medical Unit Subcommittee 

A new publication from the Incident Medical Unit Subcommittee is now available. The NWCG Standards for Rapid Extraction Module Support, PMS 552 will be used as a guide and as an opportunity to begin to build out Rapid Extraction Module Support (REMS) modules for the remainder of Fire Year 2024. These standards will be fully implemented as the minimum standard starting in January 2025.

NWCG Standards for Rapid Extraction Module Support outlines the roles, duties, qualifications, and equipment pertinent to REMS. A REMS team, strategically stationed at wildland fires, plays a pivotal role in prioritizing swift access and medical treatment to injured or ill firefighters for safe and efficient egress off the fireline. This ensures their rapid transport to definitive medical care in cases of emergency during firefighting operations, highlighting the invaluable contribution of the REMS team to firefighter safety and well-being.

National Wildland Firefighter Day

Date: July 2, 2024
Contact: National Interagency Fire Center 

The National Wildfire Coordinating Group (NWCG) would like to recognize July 2, 2024, as National Wildland Firefighter Day (NWFFD). Established in 2022, NWFFD honors the dedication of wildland firefighters and support personnel. This day falls within the 2024 Week of Remembrance (June 30 - July 6), providing an opportunity to renew our commitment to wildland firefighter safety while remembering those who have fallen in the line of duty.

NWCG continues to provide leadership to enable interoperable wildland fire operations among federal, state, local, Tribal, and territorial partners. NWCG standards and training establish common practices to contribute to safe, effective, and coordinated national interagency wildland fire operations.
