Hydrogen Sulfide

Hydrogen Sulfide MSDS

What is Hydrogen Sulfide?

Hydrogen Sulfide is colorless, has an odor of rotten eggs, and is highly toxic. Although the odor is very pungent at first, it quickly deadens the sense of smell, so victims may be unaware of its presence until it's too late. Hydrogen Sulfide is flammable, naturally occurring in crude petroleum, natural gas, volcanic gas, and hot springs. It is sometimes called “sewer gas”. Biogas generators may release up to 1% hydrogen sulfide in gas streams. Any process that breaks down organic material without oxygen has the potential to create high levels of hydrogen sulfide. If heated under pressure it will explode. It is produced in the human body by bacteria in the mouth and gastrointestinal tract. Hydrogen Sulfide is very toxic to aquatic life and leaves long-lasting damage.

Hydrogen Sulfide Exposure and Health Risks

Hydrogen Sulfide is toxic and flammable. It is an irritant, causing inflammation and irritation to eyes and respiratory system. Eye pain, conjunctivitis, photophobia, corneal vesiculation and lacrimation (discharge of tears) are effects of Hydrogen Sulfide on the eyes. Dermal burns can result from direct contact. Inhalation can cause dizziness, headaches, insomnia, and fatigue. Gastrointestinal disturbances may occur as well. Hydrogen sulfide causes serious damage to organs and central nervous system, and it can be fatal if inhaled.
