PMS412 2025 Update

Update:3/28/24 - It has come to our attention there may be a technical issue with the publication of PMS 412. The pictures and diagrams after page 100 are blurry and poor quality overall. NWCG has been notified. Hopefully they can quickly fix the issue and republish PMS412. Due to this, we have removed copies of the it from our website. Once a fix is released, we will add it back to the website.

The new version of PMS412 Guide to Wildland Fire Origin and Cause Determination has been published. A pdf is available from the NWCG website and can be downloaded here. SWAIT contributors Scott Fischer and Ed Nordskog rewrote the new Chapter 8: Wildfire Arson Recognition (formerly Chapter 7: Arson Recognition). The new version of the document includes updates to the cause categories. This update reflects the changes made by NWCG to the cause categories in 2021. There are other updates throughout the document. Make sure you start this year’s fire season right by reading PMS412. Printed copies will be available to purchase from NWCG at a later date.

FI210 is also being updated to reflect the changes made in the new addition of PMS412. The update is primarily focused on the power point presentations. The new presentations will be reviewed by the NWCG Wildland Fire Investigation Subcommittee during their next meeting the week of April 21. After this meeting the presentations will be sent to NWCG publishing. The date of public release for the new presentations has not been set. Publishing will likely take a several months to complete. We will put out an updated post once we hear when they will be released.
