Question 228Safety & Environmental - 1st Asst/Chief70% to pass
To prevent the spread of fire by convection you should _______________.
AI Explanation
The correct answer is C) close all openings to the area.
Closing all openings to the area around a fire helps prevent the spread of the fire by convection. Convection is the transfer of heat through the movement of a fluid, such as air or gas. By closing all openings, you restrict the airflow that could feed the fire and allow the hot gases and flames to spread to other areas through the openings.
The other options are not as effective in preventing the spread of fire by convection. Cooling the bulkhead (A) and removing combustibles (D) may help contain the fire, but they do not directly address the convection aspect. Shutting off electrical power (B) is a good safety measure, but it does not specifically address the spread of fire by convection.
