Toxic gases can vary significantly in smell depending on the substance. For example, chlorine gas has a sharp, pungent odor similar to bleach, whereas hydrogen sulfide smells like rotten eggs. Some toxic gases, like carbon monoxide, are odorless, making them especially dangerous because they can't be detected by smell alone. It's crucial to have the right detection equipment in places at risk of toxic gas exposure.
