What is a primary type of injury caused by liquid Ammonia exposure?

Liquid ammonia exposure can lead to several types of injuries, each stemming from its physical and chemical properties. The primary type of injury caused by liquid ammonia exposure is a chemical burn. When liquid ammonia comes in contact with skin or mucous membranes, it can cause severe damage due to its alkaline nature, resulting in both irritation and chemical burns.

In addition to chemical burns, ammonia can also cause thermal burns. This occurs because liquid ammonia is extremely cold, typically around -29°F (-34°C), which can lead to frostbite-like injuries upon contact with skin. The risk of dehydration burn comes from the rapid evaporation of ammonia under certain conditions, which can draw moisture from the skin, leading to additional skin irritation.

Hence, all three injury types can indeed be attributed to liquid ammonia exposure, making the most comprehensive answer that encompasses these risks the correct choice. Understanding these risks is crucial for anyone working in environments where liquid ammonia is present, as it helps in establishing safety protocols and first aid measures.
