This course (WHMIS2015) was honestly PAINFUL to do. I get that you're trying to make it interactive and whatever... But it was UNCLEAR, and only really focused on the story of trying to save Caleb. I've done WHMIS many times. Like, at least 15. I could teach it. This course didn't deliver the required information effectively. If this were my first time, I would have no idea. Again... I get what you're trying to do. But if it ain't broke, don't fix it. You don't need to reinvent the wheel. Stick with a 30 minute course, matching symbols etc, and actually LEARNING the material. Trust me... People are going to get more from that than a painful, drawn-out 3 1/2 hour one.
