Which chemical irritant is associated with a smell like rotten eggs?

The chemical irritant that is associated with a smell like rotten eggs is hydrogen sulfide. This compound is well-known for its distinct odor, which is often described as similar to that of rotten eggs or sulfur. Hydrogen sulfide is a colorless gas that can be produced naturally from the decay of organic matter or through industrial processes. Its strong smell makes it identifiable, but it's important to note that high concentrations can be extremely dangerous and may cause unconsciousness or even death, as it is highly toxic.

In the context of identifying chemical irritants based on their sensory characteristics, recognizing hydrogen sulfide's odor is a critical aspect of safety training, especially for individuals in fields such as medical support and hazardous material handling. Understanding this characteristic allows personnel to take appropriate actions to avoid exposure and to implement safety measures, ensuring a safer environment.
