When attempting to enter a compartment containing a fire, which method of applying water is best?

🔍 Key Concepts

• Firefighting water streams: differences between straight, solid, and fog streams • Compartment entry tactics: protecting firefighters while cooling and not spreading the fire • Thermal layering and steam production inside an enclosed space

💭 Think About

• Which stream pattern gives you the most protection from heat and flames as you first open the door to a burning compartment? • In an enclosed space, how does directing water at the overhead versus directly at the fire affect heat, steam, and potential injury to personnel? • How does a sweeping motion with a fog pattern change the atmosphere inside the compartment compared to a fixed stream at one point?

✅ Before You Answer

• Verify which method minimizes the chance of pushing fire and hot gases deeper into the compartment or onto escape routes • Check which stream type provides maximum cooling and protection for the hose team at the doorway • Confirm which technique is recommended for initial entry into an enclosed, burning compartment, not for open-deck fires
