Hydrosulfuric acid, Sewer gas, Sulfuretted hydrogen Colorless gas with a strong odor of rotten eggs. [Note: Sense of smell becomes rapidly fatigued & can NOT be relied upon to warn of the continuous presence of H<SUB>2</SUB>S. Shipped as a liquefied compressed gas.]

Hydrogen sulfide (H2S) is a colorless, highly toxic, corrosive, and flammable gas that has a distinct “rotten egg” smell. It can be present in (sour) crude oil and natural gas, but it can also form from the decomposition of organic material by bacteria.

OSHA/HCS status :This material is considered hazardous by the OSHA Hazard Communication Standard (29 CFR 1910.1200). Extended exposure to gas reduces the ability to smell sulfides. May form explosive mixtures with air. Read and follow all Safety Data Sheets (SDS’S) before use. Read label before use. Keep out of reach of children.
