Jeff Morrison
Assistant Manager - Oil Refining Operations
It was a good training. Now that I am working in a situation where there is a possibility for me to be exposed to H₂S gases, I was happy to learn what OSHA says about hydrogen sulfide and how to be prepared in the case of a disaster occurring.
Roger Deanson
Supervisor Mining Operations
The lessons helped me to clearly understand the hazards of hydrogen sulfide and how to prepare myself for any H₂S gas leaks while at work.
Chad Baker
Petrochemical Engineer
Engaging course and the animations to explain some of the key points were very helpful.
Paul Bryan
Loader Operator
"I usually don't like wearing a mask when I'm at work, but my hydrogen sulfide training taught me the importance of wearing one without putting my life in unnecessary danger by not following simple safety rules. A good course!"
Gary Joseph
System Repair technician
"My co-worker suggested that I take the H₂S course from HAZWOPER OSHA. It only took me 4 hours to finish it but the best part was that the course covered all the important safety points."
Henry Franklin
Field Operations Associate
"I needed to have my hydrogen sulfide training certificate before I could begin working. I'm really happy to have received my training certificate from HAZWOPER OSHA as I now know that I am ready to face the dangers at my work site."
