New from FSRI: Low-Intake, High-Exhaust Fires and Flow Paths

Posted on by

The UL Fire Safety Research Institute (FSRI) has launched a new training program designed to help firefighters better understand and respond to low-intake, high-exhaust fire scenarios. This critical training enhances situational awareness, tactical decision-making, and overall firefighter safety when faced with dangerous fire flow paths.

A TRAINING PROGRAM DEDICATED TO FIREFIGHTER TIMOTHY KLEIN

This training is dedicated to Firefighter Timothy Patrick Klein, who tragically lost his life on April 24, 2022, while battling a wind-driven fire in Brooklyn, NY. His sacrifice underscores the need for continuous education and preparedness in the firefighting community.

KEY TAKEAWAYS FROM THE TRAINING

✅ Understanding Low-Intake, High-Exhaust Fires

These fires create hazardous flow paths that put firefighters at high risk. Recognizing these dangers is crucial for fireground safety.

✅ Situational Awareness

Firefighters must identify when they are operating in the exhaust portion of the fire’s flow path to avoid injuries caused by extreme heat and smoke movement.

✅ Strategic Decision-Making for Officers

Company officers play a vital role in making critical tactical decisions to protect their crews in these high-risk scenarios.

✅ Video-Based Learning for Realistic Training

The program includes video simulations that demonstrate how low-intake, high-exhaust conditions develop and impact fire dynamics.

✅ Hands-On Training Resources

A training handout is available to facilitate continued discussions and reinforce key lessons with firefighting teams.

  1. Don’t know if the training might mention it but I believe the double LODD fire on Beacon St. in Boston (2014 … Lt. Ed Walsh, FF Michael Kennedy, may the rest in peace) was a “low-intake”, high-exhaust” fire where the members were trapped by a unidirectional flow path. It was also a wind-driven fire. There were also issues of uncontrolled ventilation (a window that failed due to the fire & doors left open by the maintenance man & the fleeing occupant).
