Fire may be spread by which means?

🔍 Key Concepts

• Methods of heat transfer in fire behavior: conduction, convection, and radiation • How fire spreads from one area or compartment to another on a vessel • The difference between direct flame contact and heat transfer through a medium (solid, liquid, gas)

💭 Think About

• For each option, ask: is this a recognized method by which heat can move from one place to another? • Think about how a fire in one compartment could ignite material in another compartment without visible flame touching it. • On a ship, consider how heat could move through metal bulkheads, through hot gases and smoke, and by radiant heat across open spaces.

✅ Before You Answer

• Verify which of the choices are actual physical mechanisms of heat transfer taught in basic firefighting theory. • Check whether convection involves movement of hot gases or liquids, not solids. • Confirm whether radiation must involve direct contact, or if it can act across an open space without touching.
