🔍 Key Concepts

• Fire behavior in closed compartments – especially heat and flame conditions near the overhead versus at deck level • Characteristics of high-velocity fog from an all-purpose nozzle (cooling, steam production, air/oxygen displacement) • Safe entry techniques into a burning space to avoid flashover and rollover overhead

💭 Think About

• Where is the hottest layer of gases usually located in a burning, enclosed compartment, and why does that matter for where you aim first? • What happens when high-velocity fog hits very hot surfaces or gases – how does it affect heat, visibility, and steam production? • Which initial nozzle direction best reduces the immediate danger from superheated gases and potential flame spread as you enter?

✅ Before You Answer

• Verify where superheated gases and rollover/flashover risk are typically found in an enclosed fire (overhead vs. deck) • Consider how steam generated from fog can protect firefighters and cool the space versus driving heat/smoke back on them • Check which option prioritizes reducing overhead heat and gas temperature before advancing into the compartment
