I want to follow on Mr. Allen's comment.
At first I thought you were suggesting that this might be redundant, that hazardous, carcinogenic chemicals are going to get their label, that adding this together and saying.... The chemicals are already coming on site where workers are exposed, so let's just narrowcast in on that, regardless of the effects on the environment, watershed, and whatnot, but just on the workers, they're already getting labelled. Was that your point?
