- Connect fuel configuration with scientific measured results (such as time temperature charts).
- Discuss factors that influence fire progression.
- Demonstrate how fuel load and configuration impact fire behavior.
- Identify the conditions leading up to flashover and backdraft phenomena.
- Discuss factors that influence fire progression.
- Review key fire-related terms such as pyrolysis, combustion, and flameover.
- Apply key fire-related terms such as pyrolysis, combustion, and flameover.
- Explain the role of thermal layering and buoyancy in fire dynamics.
- Explain the concept of flowpath in structural fires.
- Predict flowpath based on fire environment.
- Describe the value and limitations of smoke reading (velocity, color, amount, etc.).
Fires within enclosures such as a room or structure present some unique challenges to firefighters. Within an enclosure a fire's behavior is impacted by pressures, both atmospheric and fire-related, as well as oxygen availability. Moreover, as firefighters enter or open the structure or room, they can significantly impact the behavior of the fire, both negatively and positively.
- 6.1: Fire Growth
- This page covers the phases of fire growth. It emphasizes the impact of heat release rates and covers key fire dynamics concepts like flashover and backdraft.
- 6.2: Flowpath
- This page explains flowpath and describes how high-pressure gases exit and low-pressure gases enter a structure.
- 6.3: Summary
- This page summarizes concepts related to fire behavior in enclosed spaces.
- 6.4: Review
- This page includes review questions about fire behavior within structures.
