CLoss of water will not harm a boiler if the water level can be restored.
DA hot boiler will continue to generate steam after the fires are secured.
AI Explanation
The correct answer is D) A hot boiler will continue to generate steam after the fires are secured. This is correct because even after the fires are secured, the water in the boiler will continue to absorb heat from the hot metal surfaces, causing the water to turn to steam. This continued steam generation can persist for some time after the fires are out, until the boiler cools down. The other options are incorrect because: A) The water level in a boiler can shrink or swell during operation, B) Boilers can continue to generate steam after the fires are secured, and C) Loss of water can damage a boiler if the level cannot be restored.
