In the presence of moisture, H2S forms sulfurous and sulfuric acids, which are corrosive to metals. Corrosion is enhanced in the presence of carbon dioxide and produced water low in oxygen content.

Metal fatigue, including hydrogen embrittlement or sulfide stress cracking, can result in a release of hydrogen sulfide gas and Injuries due to equipment failure.

You should pay attention to any corrosion signs when you are around equipment  as this may pose a severe hazard.
