70% to passWhat is the purpose of opening the doors and portholes in figure 2 of the illustration? Illustration SF-0013
ATo keep the hose teams cool.
BTo allow water used to fight the fire to flow out of the superstructure.
CTo allow venting of combustion products from the fire to the atmosphere.
DTo provide air flow around the compartment in the order to contain the fire.
AI Explanation
The correct answer is C) To allow venting of combustion products from the fire to the atmosphere. Opening the doors and portholes in this scenario helps vent the smoke and other combustion products from the fire to the outside atmosphere. This improves visibility and reduces the buildup of toxic fumes inside the compartment, which is critical for the safety of the firefighting crew. The other options are incorrect because they do not address the primary purpose of venting the combustion products. Allowing water drainage (B) and providing air flow (D) are secondary benefits, but the main reason is to remove the hazardous smoke and gases from the enclosed space.
