Question 231Safety & Environmental - Assistant Engineer

The correct answer is C) conduction. Fire spread by conduction occurs when heat travels through a solid material, such as the bulkhead or wall separating the two compartments. In the illustration SF-0013, fire in compartment "A" would conduct heat through the solid bulkhead or wall, eventually causing the temperature to rise in the adjacent compartment "B", leading to the spread of the fire. The other options are incorrect because: A) convection involves the transfer of heat through a fluid, such as air or water, which is not the primary mode of fire spread in this case; B) radiation involves the transfer of heat through electromagnetic waves, which is not the dominant mechanism here; and D) impingement refers to the direct contact of the flame or hot gases with the adjacent surface, which is not the primary focus of the question.
