Q

Ventilation systems connected to a compartment in which a fire is burning are normally closed to prevent the rapid spread of the fire by which method?

🔍 Key Concepts

• Methods of heat transfer in fires: radiation, conduction, convection • How air movement and ventilation affect fire growth and spread • Role of ventilation ducts and fans in carrying heat and smoke

💭 Think About

• Think about which method of heat transfer depends on moving hot gases or fluids from one place to another • Consider what happens inside ventilation ducts when a fire is drawing in more air and pushing out hot smoke • Ask yourself: which heat transfer method could turn ventilation ducts into a pathway that spreads fire rapidly through a ship?

✅ Before You Answer

• Be clear on the definitions of radiation, conduction, and convection • Identify which method involves circulation or movement of heated air or gases, not just direct contact or heat waves • Confirm which heat transfer method is most directly affected when you shut off fans and close ventilation dampers
