I'll try to clarify...
Using a product, (i.e. pesticide) according to the directions is fine. An Emergency Plan (EP) is for what you do in case of an
accidental discharge.
Ever knock over a bag of DE or have it fall of the tailgate and break open? That is an accidental discharge and what did/do you do to clean it up. Same with a jug of bleach or bottle of ACV.
There is no difference in "food grade" in case you spill it while you are eating it.
The process sounds more complicated than it really is. Most of it is common sense with a few "I did not know that" things thrown in. ( I did not know that I should keep my gas can inside another tote in case I knock it over. A $2 tote would keep that $20 worth of gas from soaking into the ground. )
Neatness is simply keeping the lids tight on feed, not setting the gas can on top of the feed can. Neatness is cleaning the poop boards on a regular schedule (suggested guideline is at least twice a year).
It is really pretty simple to be compliant and practice good animal care. I'll find out in a few days how that compliance helps in a court of law, but I do know one case where is was a deciding factor in the farmer's win.
