What is one of the symptoms of exposure to hydrogen sulfide gas?

1. Rash

2. Euphoria

3. Stomach distress

4. Thirst

The correct answer is: Stomach distress

Hydrogen sulfide gas is a toxic compound often characterized by a distinctive rotten egg odor. Exposure to this gas can lead to a variety of health symptoms, with stomach distress being one of the more common reactions. The gas can irritate the gastrointestinal tract, leading to symptoms like nausea, vomiting, and abdominal discomfort. This occurs as the body reacts to the toxic nature of the gas, which can affect various systems. The other symptoms listed, such as rash, euphoria, and thirst, are not typically associated with exposure to hydrogen sulfide in the same direct way. While euphoria might be a transient effect due to its initial capacity to dull senses at low concentrations, it is not a reliable or common symptom. Similarly, rash and thirst do not directly relate to the acute physiological impacts of hydrogen sulfide exposure. Understanding the primary symptoms, particularly stomach distress, is crucial for recognizing and responding to potential hydrogen sulfide exposure on job sites or in environments where the gas might be present.
