Question 6Safety & Environmental - Assistant Engineer

The correct answer is C) fire boundary. When fighting a shipboard fire, the crew members securing doorways, hatches, and applying cooling water to adjacent decks and bulkheads, while monitoring the spread of heat and smoke, are setting a fire boundary. This is a critical tactic in firefighting to prevent the fire from spreading beyond a specific area and to protect adjacent spaces from the effects of the fire. The goal is to establish a controlled perimeter around the fire to contain and extinguish it, which is known as setting a fire boundary. The other options are incorrect because a "safety perimeter" is a broader term that may not specifically refer to firefighting tactics, a "cooling zone" is a more general term for an area where cooling water is applied, and a "buffer zone" is not a commonly used term in this context.
