H2S
A 2-hour online course on hydrogen sulfide: where it's found, how it's detected, respiratory protection and emergency response. Pass with 80% for a certificate valid for 3 years.

Who this course is for
This course is for workers who could be exposed to hydrogen sulfide on the job and need to understand the hazard: how it forms, where it collects, how it is detected, and what to do in an emergency.
- Workers whose employer accepts an online H2S course for their role
- Anyone who needs Continuing Education Units. The course is approved by Alberta Environment & Parks for CEUs.
- Anyone who wants to learn the hazard and the emergency steps at their own pace
What you will learn
Hydrogen sulfide smells like rotten eggs, but it can dull your sense of smell. It can also build up in low-lying areas and confined spaces. That is why the course spends time on detecting the gas instead of trusting your nose.
- What H2S is, how it forms and where you are likely to find it
- Assessing atmospheric hazards and using the hierarchy of controls
- Who is responsible for what under health and safety law
- Respiratory protective equipment: the types and how to pick the right one
- How H2S is measured, safe working limits, detection devices and sampling
- Managing an emergency scene and first aid for H2S exposure
Course length, pass mark and certificate
Plan for about two hours. Short tests run through the course, and you need 80% to pass. If you fall short the first time, you can repeat the course twice. When you pass, you download and print your certificate of completion. It is valid for three years.
Need H2S Alive?
H2S Alive is a separate one-day classroom course from Energy Safety Canada, with hands-on practice using breathing apparatus and rescue drags. This online course is not equivalent to it. If a job posting, site or prime contractor asks for H2S Alive by name, book that course instead.

H2S: common questions
Is this the same as H2S Alive?

How long is the certificate valid?
Three years from when you complete the course.
What mark do I need to pass?
You need 80%. If you do not reach it on your first try, you can repeat the course twice.

Is there a time limit for online courses?
Everyone learns at a different pace and everyone retains information differently. When you take a course online, you go at your own speed. If you get to a certain point and don’t fully understand the material, you can pause and go back for a review. On the other hand, if everything makes perfect sense, you can go straight through the entire course right to the test.
How does virtual proctoring/testing with webcam monitoring work?
When you start your test, you will be monitored via your webcam. If you disappear from the screen or appear to be consulting another device or other material, you will be disqualified from the course. The company responsible for virtual proctoring is Integrity Advocate. You can find out more about how their system works here.
