Just to clarify for us, when a substance--for example, ammonia--is placed on schedule 1, there's no context provided. It's on the list; it's on schedule 1 because a risk assessment has been done about a particular use that has warranted its being placed on schedule 1, meaning it needs to be managed. When something's on the list, all of its uses automatically, across the board, are deemed CEPA-toxic, when in fact they're not.
