When chemical carriers load high value and very pure products, they will commence loading until about one foot of cargo is in the bottom of the tank, then stop. They will take a sample this cargo, known as the foot sample up the facility's lab for analysis to see if during the loading of this one foot of cargo there was any contamination. If not, they will resume loading the tank until completion. If contamination is present in the foot sample they will try to determine the source, while they pump the now off spec cargo to the shore, and start over again, It is hoped that the amount loaded during the foot of cargo is enough to clean the contamination from the tank and piping. This is done to prevent the entire tank being loaded and then contaminated thereby requiring the full cargo to be reprocessed.
