Online Hydrogen Sulfide (H2S) Training

This 100% 3D-animated, high-quality safety training program will teach you everything you need to know and understand in order to safely work at sites where H2S may be encountered.

Are there other names for hydrogen sulfide?
Hydrogen sulfide is known by many names, including;

• H2S

• Sulfane

• Sulfur Hydride

• Sour Gas

• Sulfurated Hydrogen

• Hydro-Sulfuric Acid

• Sewer Gas​

• Stink Damp

​
Regardless of what you call it, hydrogen sulfide is always the same deadly gas. Effective training is critical to ensuring that workers understand the physical and chemical properties of H2S, the signs and symptoms of exposure, as well as the appropriate emergency response in the event of a release.

What makes hydrogen sulfide so dangerous?
Hydrogen sulfide is approximately 20 percent heavier than air, as well as corrosive, highly flammable, and an extremely toxic gas.  H2S is also water soluble, which means hydrogen sulfide can be absorbed by water and hydrocarbons. When this occurs, it forms a weak sulfuric acid. This weak sulfuric acid, over time, can also lead to the formation of iron sulfide scale (an air-reactive). These serious, life-threatening hazards of hydrogen sulfide are often overlooked and the uninformed/untrained worker can easily fall victim to this very deadly gas.

Won't PPE alone keep me safe?
Engineering controls are often the most effective and desirable method for dealing with the potential presence of hydrogen sulfide in the workplace, but engineering controls are just that. They're controls. They're not guaranties. And effective employee training along with adequate personal protective equipment(PPE) are equally important to ensuring workers are prepared for the potential of encountering this very dangerous gas. 

This course was designed using the ANSI 390.1 (Accepted Practices for Hydrogen Sulfide Safety Training Program) recommended course outline. This course helps employers meet their training requirements found in 29 CFR 1910 and 29 CFR 1926. A printable course certificate is available for immediate download and printing upon course completion.
