Which H2S Course Do You Need?
eTraining sells H2S training in two languages, and the gas shows up in confined spaces often enough that some crews need both courses. Here is how the three sort out.
- Hydrogen Sulfide (H2S) Training. The course on this page, in English. About three hours covering detection, exposure limits, protective equipment, emergency response and the confined space hazards H2S creates. Buy this one for crews working around sour gas, wastewater or manure storage. View the Hydrogen Sulfide (H2S) Training
- Hydrogen Sulfide (H2S) Training - Spanish. The same subject matter, narrated in Spanish, with the exam in Spanish too. Buy this for Spanish-speaking crew members rather than putting them through the English version, so the part that has to stick is in the language they work in.

- Confined Space. H2S training explains why confined spaces are where the gas collects. If your crew actually enters permit-required spaces, they need entry training on top of it: atmospheric testing, permits, attendants and non-entry rescue. View the Confined Space
Buying for a mixed crew, take the English and Spanish H2S courses together. Add Confined Space for whoever goes through the hole.
How Long Does H2S Training Stay Current?
No federal rule puts an expiry date on H2S training. OSHA's Hazard Communication standard at 29 CFR 1910.1200(h)(1) ties the training to the job rather than to the calendar, so what sets your refresher schedule is usually your employer and the sites you work on.
- The standard triggers on assignment, not on a date. 29 CFR 1910.1200(h)(1) requires training at the time of initial assignment, and again whenever a new chemical hazard is introduced into the work area. There is no annual clause anywhere in it.
- Your employer and the site operator set the interval. Plenty of operators and plant contracts ask for a refresher every twelve months. That is a contract requirement rather than a federal one, so check what your sites ask for before you buy.
- The certificate carries the date you passed. Your Certificate of Completion is personalized and dated, so a gate guard or an auditor can see when the training happened without you having to explain it.
If your sites ask for a refresher every twelve months, put the renewal on the same calendar as your gas detector calibrations. It stops being a scramble.






I really liked the course.
The H?S training was informative and easy to understand. It provided a clear understanding of H?S hazards, safety precautions, detection, and emergency response procedures. Overall, it was a valuable learning experienced.
