Once upon a time I was given a job to train employees on safety issues. Well, I did my homework, studied the regulations, scheduled training, and completed my tasks. Unfortunately, it came off with all the enthusiasm of a bad high school class. Retention was probably null. The first year training was completed, but ineffective.
Second year training rolled around and I approached it from a more creative angle. First lockout/tagout came up. I started with the basic videos, but added a hands-on training section. And I decided all upper management should attend. This tends to keep attention on the training - ever try to sleep in front of your boss?
