🔍 Key Concepts

• Fire triangle (heat, fuel, oxygen) • Difference between extinguishing a fire and preventing its spread • How each action affects one side of the fire triangle or nearby materials

💭 Think About

• Think about what must be present for fire to continue burning and what you can do to stop it from extending to new areas. • For each option, ask yourself: Does this action reduce heat, remove fuel, or limit oxygen in a way that stops the fire from spreading? • Consider whether more than one of these methods could logically help prevent a fire from moving into adjacent spaces.

✅ Before You Answer

• For each choice, identify which part of the fire triangle it affects: heat, fuel, or oxygen. • Decide if preventing spread can involve more than one method at the same time or if it must be only one specific method. • Verify that the option you select includes all effective ways listed, if more than one clearly helps prevent extension of the fire.
