What is the Navy's standard for hydrogen sulfide (H2S) exposure?

The Navy's standard for hydrogen sulfide (H2S) exposure is established at 10 parts per million (ppm). This level is set to ensure safety and minimize health risks for personnel who may encounter this hazardous substance in their work environment. Exposure to H2S can lead to serious health consequences, including respiratory issues and other acute symptoms. Hence, the 10 ppm threshold functions both as a protective measure and as a guideline for operational protocols to mitigate potential risks associated with H2S exposure. Understanding this standard is crucial for personnel working in environments where hydrogen sulfide might be present, ensuring they adhere to safety practices that keep exposures within this accepted limit.
