How fire behavior affects risk to firefighters.

Special Delivery Considerations

S-190 may be delivered as instructor-led (classroom) or self-directed (online) training.

NWCG training materials are being updated to reduce redundancy and conflict among overlapping documents. Course-specific student workbooks will be replaced by standards-bearing NWCG publications - the documents that actually guide operations. Instructor guidance will be integrated into PowerPoint presentations rather than located in separate documents. Instructors may use the instructor guide file (exported from the PowerPoint presenter notes), view the notes in presentation mode, or export the notes into the desired format.

Special Cadre Considerations

Conduct initial, pre-course, daily, and close-out instructor cadre meetings. These provide opportunities to plan, organize, preview materials, review training and exercises, and identify and address concerns and issues. Consider using an informal After Action Review process. Instructor cadre meetings are critical for instructors who do not have previous experience with the course. Additional information is located in the NWCG Standards for Course Delivery, PMS 901-1.
