An oil or water-tight, zinc-lined box or tray shall be securely fastened under the taps or faucets of all oil or delivery wagons or trucks.
In filling any measure or other vessel from the taps or faucets on a delivery tank or wagon, the measure or other vessel shall be held so that any drip or overflow shall flow into the box or tray required under § 1006.3.
In removing the measure or other vessel from over the pavement, no drip or overflow from the measure or other vessel shall be permitted to fall upon the pavement, and no receptacles for holding oil shall be placed on the pavement.
