New FSRI Online Training Addresses the Low Intake, High Exhaust Flow Path Resources
We’re excited to announce the launch of a set of new training resources designed to help the fire service better understand and respond to low-intake, high-exhaust fire scenarios.
This set of resources includes:
1. Lesson the Fire Safety Academy (FSA) –

These resources will assist firefighters in executing specific tasks that promote safe and effective operations while maintaining situational awareness. In addition, they will support company officers in making strategic decisions that protect their crews.
Thank you to Madi Michael for leading the development of the handout and the rest of the Education & Training team for their review and support. The video would also not have been possible without the animation and editing expertise of Doug Mansen. Lastly, thank you to FDNY and their collaboration on this project.
These resources are dedicated to Firefighter Timothy Patrick Klein. On April 24, 2022, while operating at Brooklyn Box 3-3 2075, Timothy made the ultimate sacrifice while battling a wind-impacted fire with a low-intake, high-exhaust flow path.
Firefighters across the country continue to be injured when operating in the exhaust portion of a fire’s flow path. This lesson simulates a low-intake, high-exhaust flow path scenario, explores the factors that lead to these dangerous conditions, and provides key takeaways to help firefighters mak...
