Sometimes what you can't smell can hurt you. Protect yourself and your team with this critical information that raises awareness of what Hydrogen Sulfide (H2S) is and discusses exposure risks and effects, toxicity, ignition, detection, prevention, and evacuation.

At the end of this module, you will be able to:

  • Define "hydrogen sulfide"
  • Describe hydrogen sulfide toxicity
  • Describe ways hydrogen sulfide exposure can occur
  • Describe hydrogen sulfide flammability hazards
  • Describe how to detect hydrogen sulfide
  • Describe how to prevent hydrogen sulfide hazards
  • Describe proper evacuation procedures in events of hydrogen sulfide exposure

The following key questions are answered in this module:

What is hydrogen sulfide?
It is a toxic and flammable gas that is heavier than air.

What are some places where hydrogen sulfide may be present?
It is found in petroleum and natural gas; is released naturally by decaying plants, animals, and sewage; is created by production of oil, paper, rayon, and leather; and can also be found dissolved in water.

What are the health effects associated with hydrogen peroxide?
In addition to burns caused by its flammability, exposure through inhalation can cause long-term health such as paralysis, nerve damage, and memory loss. Inhalation can also lead to death.

How can hydrogen sulfide be detected?
When the gas is in the air at low concentrations, it has a distinct rotten-egg smell, but this smell quickly goes away as the nose gets used to it and/or as concentrations of the gas in the air increase. Therefore, you can't trust you nose as a foolproof guarantee. Personal gas monitors can be used to detect the gas more reliably.

What should you do in the event of a hydrogen sulfide exposure?
? Leave the area immediately and seek medical care if necessary. Remember when evacuation to that the gas will be in low-lying areas and to evacuate upwind.

What if a coworker has lost consciousness and cannot evacuate?
Don't try to rescue the coworker yourself. Instead, evacuate and then call for help.

Below is a transcript of the video sample provided for this module:

Hydrogen sulfide is a toxic gas which is encountered in a wide variety of industries. While it is not the number one industrial danger, there were approximately a dozen deaths per year in the period 1992 to 2002, which were attributed to the gas. This module describes the dangers of hydrogen sulfide and how those risks can be reduced.

Customer Reviews


Great Video

“Very clear and concise. Would recommend to others HSE coordinators.”

Thomas Takada Verified Customer


My Employees Really Liked It!

“It's very rare I have an employee, let alone several come back to tell me they enjoyed a safety video. I received several compliments on the H2S video, especially on how informative it was. In the natural gas industry, this is an important topic, and it's nice to have a training tool that employees find helpful and enjoy at the same time.”

Jamie H. Verified Customer


H2S Awareness Video

“This video is great for introducing volunteer fire fighters to the hazards associated with Hydrogen Sulfide. These fire fighters respond to vehicle accidents and fires or rescue situations which may contain H2S.”

Sorry, we're missing some information

How do I log in to watch a video that I have already paid for?

Easy! Moments after you purchase your pay-per-view (PPV) course, you'll receive an email with login details. Just click the link and log in with your user name and password and you're on your way!

I would like to have some of my employees take 5 of your driving related courses, how can i set this up?

We're in the process of making bulk purchases and purchases for multiple users easier. But for now, you can order multiple courses and just let us know who you'd like to assign courses to. With an email for each user, we can set up their training plans and make sure everyone gets the eLearning assignments they need.

How can I get your paper-making courses for free?

Well, we can't blame you for asking... And while we're a for-profit company, there are situations with students and certain educational organizations where we can help out with a selection of eLearning. However, our online courses are extremely economical. And our paper industry courses are in very high demand. So, without knowing more about your situation, we think you'll get loads of value from the $39 you'll spend on any of our premium courses.

Do you have eLearning in Portuguese?

Yes, we do! And in addition to primary English narration, we produce many courses in a growing number of languages, including Spanish, Chinese, Dutch, German, Italian, Japanese, Korean, Polish, Russian, Tamil, and Thai.

I'm unemployed, but I really like your eLearning. Do I get a certificate when I complete a course?

Yes! All of our courses allow you to print a completion certficate upon successfully passing the integrated test at the end of eLearning. In the future, we'll have badges for you to use in your LinkedIn profiles.
