Also, using your taxiing and jet blast examples, maybe you should open your eyes on the ramp. I see someone cut off a taxiing aircraft at least monthly, and someone get jetblasted several times a week. While YOU may not think you need some of these courses, other people do need them. You probably do too, you're just too ignorant to realise it.
It's a fact: common sense ain't so common. There's a difference between carelessness and stupidity though neither are difficult to find.
Most of those modules are just the company covering it's arse in case somebody does get hurt doing something incredibly stupid and then tries to turn around and say that they were never trained properly. This is also more or less why coffee containers from chain establishments have warnings on them telling you that the hot coffee within is...hot.
Some of these are government mandated like the HazMat stuff; in that case I'd rather spend 20 minutes in front of a computer screen than an hour flipping through that stupid booklet.
Also some of these are actually useful, such as the different types of fire extinguishers and how they're used. I know, it seems stupid when you're sitting there but not so when you're in the bin and the belt loader catches on fire (seen it)...
