Question 633 Deck Safety

The correct answer is C) close all openings to the area. Closing all openings to the area is the best way to prevent the spread of fire by convection. Convection is the transfer of heat through the movement of hot gases or fluids, and by closing off openings, you can prevent these hot gases from spreading the fire to other areas. This is a key principle in fire prevention and containment. The other options are not as effective in preventing convection. Shutting off electrical power (A) may help in some cases, but does not directly address the convection issue. Removing combustibles (B) and cooling the bulkhead (D) can be helpful, but do not specifically target the convection pathway.
