Question 70Safety & Environmental - QMED
70% to passIn the event of a fire, the doors to a stair tower must be closed to prevent the spread of fire by _______________.
Aconduction
Bradiation
Cventilation
Dconvection
AI Explanation
The correct answer is D) 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 fluids, such as air or smoke. By keeping the stair tower doors closed, it prevents hot gases and smoke from traveling through the stair tower and spreading the fire to other areas of the building. This helps contain the fire and slows its progression. The other answer choices, conduction, radiation, and ventilation, are not the primary mechanisms by which fire spreads in this scenario.
