Investigations by the National Institute for Occupational Safety and Health (NIOSH) have revealed numerous cases of firefighter fatalities and injuries due to flow path-related incidents. Understanding the science behind fire dynamics and flow paths is critical for firefighter safety.

 

Course Overview

The term “flow path” may sound new, but the concept isn’t. In its simplest form, it describes how fire, heat, and smoke travel through a structure when influenced by ventilation openings.

 

While firefighters have long known the impacts of venting fires—breaking windows, opening doors, roof ventilation, and even entering the front door—modern research is challenging old myths.

• Is it better to vent early, or hold off?

• Most importantly, how do we prevent firefighters from being caught on the wrong side of a flow path?

 

Key Takeaways:

From analysis of NIOSH reports, here are common themes this course will address:

1. Entry Considerations - Firefighters often enter structures through the front door, potentially against a prevailing wind that intensifies fire behavior.

2. Wind Awareness - Wind direction and velocity are rarely factored into entry decisions, creating significant risks.

3. 360-Degree Size-Up - Rapid deployment without locating the seat of the fire or conducting a full size-up can be fatal.

4. Above-the-Fire Hazards - Advancing above the fire without realizing the dangers can lead to disastrous outcomes.
