In figure 1 of the illustration, fire would spread to compartment "B" by __________. Illustration SF-0013

Correct Answer: Option C — conduction

Conduction is the transfer of heat through solid materials. In shipboard fire scenarios, heat travels through steel bulkheads and decks, raising the temperature of adjacent compartments. This necessitates boundary cooling to prevent the ignition of combustible materials on the unexposed side of the steel structure.
