🔍 Key Concepts

• High-velocity fog stream behavior in confined spaces (passageways and compartments) • Principles of ventilation in firefighting: where heat and smoke go, and why an exit path matters • Dangers of pushing heat and smoke toward other parts of the vessel or trapped personnel

💭 Think About

• When you use a high-velocity fog stream to push heat and smoke, what must happen to that heat and smoke after it moves down the passageway? • In a shipboard fire, what could go wrong if you drive smoke and heat forward with no way for them to escape? • Which option describes a condition that makes this fog tactic safer in terms of controlling the path of smoke and hot gases?

✅ Before You Answer

• Which choice talks about where the smoke and heat will go after being driven ahead? • Eliminate any choices that focus only on equipment size or number of hoses without addressing smoke and heat movement. • Ask: Which condition reduces the risk of forcing heat and smoke into uninvolved spaces or toward personnel?
