It's very difficult. For example, you couldn't create an omnibus training program that would cover all 2,200 dangerous goods or even those in that smaller number of dangerous goods. It would end up being so watered down that it would be meaningless. I think the system is working fairly well right now between shippers and carriers in terms of providing that product knowledge and that sort of thing.
One thing we do recommend be looked at is whether the people providing the training, whether within a company or through a third party institution of some sort, have proper training not only in dangerous goods but in terms of how to train people and whether they are getting the proper training. We think there needs to be some sort of a certification process for the trainers themselves. You'll see lots of ads in newspapers for people providing training, and it's not always clear that they know what they're doing.
