Question 628Deck Safety70% to pass
In the event of a fire, the doors to a stair tower must be closed to prevent the spread of fire by _______________.
AI Explanation
The correct answer is C) convection.
Closing the doors to a stair tower during a fire helps prevent the spread of fire through convection. Convection is the transfer of heat through the movement of a fluid, such as air or smoke. By keeping the stair tower doors closed, it helps contain the hot gases and smoke within the fire area, preventing them from spreading through convection to other parts of the building. This helps protect the stair tower and allows for safe evacuation of the building.
The other answer choices are incorrect because conduction (A) is the transfer of heat through direct contact, radiation (D) is the transfer of heat through electromagnetic waves, and ventilation (B) refers to the flow of air, which can contribute to the spread of fire if not properly managed.
