Disposal
Do not reuse product containers. Dispose of product containers, waste containers, and residues according to local, state, and federal health and environmental regulations.
My Note: Normal prudent handling of such products in ag industry is triple rinsing with reuse of rinsate and then punching hole in container and/or crushing for disposal.
An interesting case is dormant oil..
Dormant Oil in State of Washington is on hazardous substance list due to use in orchards and annual use requires a usage tax fee. It is 99.9% mineral oil, i.e., same as baby oil without perfumes. The perfumes in commercial baby oil have higher toxicity in their neat form than the dormant oil.
