HYDROGEN SULFIDE, WET HOT Chemical compatibility with O-rings, rubbers, & plastics

Hydrogen sulfide (H₂S) is a colorless, highly toxic gas with a characteristic rotten egg odor, used in various industrial processes. In its wet, hot form, H₂S is encountered in petroleum refining, metal processing, and geothermal energy production. Despite its utility, hydrogen sulfide poses significant health hazards, including respiratory distress, pulmonary edema, and systemic toxicity. It is also highly flammable and can form explosive mixtures with air. Proper handling, storage, and stringent safety measures, including adequate ventilation and gas detection systems, are essential to minimize risks. Personal protective equipment is crucial to ensure safe usage and prevent exposure.
