Hydrogen Sulfide (H2S) Monitoring Services

Hydrogen sulfide (H2S) is a highly toxic gas. It is produced naturally and as a result of human activity. It smells like rotten eggs, colorless and heavier than air. This gas can dissolve in water and will be released from the water when stirred. Because it is heavier than air, it tends to accumulate at the bottom of poorly ventilated spaces. Although very pungent at first, it quickly deadens the sense of smell, so potential victims may be unaware of its presence until it is too late.
