Hydrogen Sulfide (H2S) Instruments:

Hydrogen sulfide (H2S) is a flammable, toxic, colorless gas that is often characterized as having a ''rotten egg'' smell. People can typically smell hydrogen sulfide at low concentrations in air, ranging from 0.0005 to 0.3 parts per million (ppm). Brief exposure to high levels of H2S can cause death, while lower, long-term exposure can lead to eye irritation, fatigue, and headaches.
