Question 9Safety & Environmental - Assistant Engineer

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.
