Fall Off Rules

National Incident Feature Services (NIFS) data in the /GISS/Event_GISSEdit feature service that are not receiving routine updates "fall off" the service and are no longer displayed. Updates can be either in the form of edited records in the service or activity in the Integrated Reporting of Wildland-Fire Information (IRWIN) database. This is done for performance reasons to reduce drawing time and simplify the end user experience.

All GIS Records with the same IRWINID should be treated as a group and the most recent date among them used for data-age queries. The process will be run twice weekly.

Data that meets the queries below will be moved to Archive:

  1. GIS Records with an IRWINID
    1. With Controlled and/or Contained Date in IRWIN:
      1. IF IRWIN controlled and contained dates are greater than 30 days AND EditDate is greater than 30 days.
      2. THEN move all features with IRWINID to Archive at the same time to ensure same GDB_TO_DATE field.
    2. No Controlled or Contained Date in IRWIN:
      1. IF EditDate is greater than 60 days.
      2. THEN move all features with IRWINID to Archive at the same time to ensure same GDB_TO_DATE field.
  2. GIS Records with an invalid IRWINID
    1. Notify wildfireresponse@firenet.gov when these records are encountered. Provide IRWINID being used and ObjectID in email.
  3. GIS Records without an IRWINID
    1. IF DateCurrent is greater than 30 days.
    2. THEN move features to Archive.
  4. GIS Records Autogenerated for INFORM (triangles)
    1. IF MapMethod=Autogenerated AND CreateDate is greater than 14 days AND DateCurrent is .
    2. THEN move feature to Archive.
  5. GIS Records with IRWINID in Event Polygon Feature Class (InFORM requirement for Final Fire Perimeter feature class)
    1. IF Event Polygon = Daily Fire Perimeter AND IRWIN record is unedited in 21 days.
    2. THEN copy the most current Daily Fire Perimeter (and associated parts) to Final Fire Perimeter Feature class.

6 Minutes for Safety Subcommittee

As we approach the 2025 Week of Remembrance (WOR), June 30–July 6, we dedicate this time to reflect on the past incidents from 2015 and honor the fallen through learning. Since its inception in 2014, WOR has honored wildland firefighters who made the ultimate sacrifice while encouraging critical discussions that reinforce lessons learned.

Questions?  Please contact:
Equipment Technology Committee

The U.S. Forest Service National Technology and Development Program (NTDP) is seeking input on the Forest Service-designed flame-resistant (FR) shirt, currently available through the National Interagency Support Cache system and FedMall.

NTDP is conducting a product review to improve future FR shirt designs. As part of this effort, a short survey is now open for federal employees who have worn any of three recent FR shirt models. Feedback will guide design improvements to better meet the needs of wildland firefighters.

To comply with the Paperwork Reduction Act, responses are limited to federal employees. The survey is open through September 12, 2025.

EMC Memo 25-001: Interim Rapid Extraction Module (REMS) Training and Qualification Requirements

Date: June 3, 2025
Questions?  Please contact:
Emergency Medical Committee

The Emergency Medical Committee has issued interim guidance for Rapid Extraction Module Support (REMS) teams. Until further notice, Type I and II REMS teams must designate a team leader qualified at Firefighter Type 1 Squad Boss (FFT1) or higher. This temporary change replaces the Single Resource Boss (SRB) requirement, which is currently not feasible due to administrative barriers.

This memorandum does not include any other changes to the NWCG Standards for Rapid Extraction Module Support, PMS 552. This interim change takes effect immediately and will remain in place until further notice.
