What the rule asks for
For a container that held an acute hazardous waste, the federal rule treats it as empty only after triple rinsing with a solvent capable of removing the product, an equivalent cleaning method, or removal of the inner liner. The rinse has to remove the product, so the solvent has to suit it. Water is not always enough.
The rinsate, the liquid that comes out, is a waste too. A triple rinse moves waste from the tote to the rinse water; it does not make the problem go away.
| Term | What it is | Food grade? |
|---|---|---|
| Rinsed | Flushed to remove the last product | No |
| Triple-rinsed | Flushed three times with water or a suitable solvent | No, unless history is documented |
| Reconditioned | Washed, inspected and certified | Only with history |
Why triple-rinsed is a grade on the form
The request form has a condition for it, because buyers use the term. A triple-rinsed tote is still the original bottle. It has been flushed to a standard, and the paperwork that says so travels with it. It is not a food-grade tote, and it is not a new one.
Before you rely on one, ask what it held and what the rinse was. A triple rinse with water of a tote that held an oil does not meet the standard for that oil.
Doing it
- Know what the tote held and use a rinse that removes it.
- Rinse three times, draining fully between rinses.
- Collect the rinsate and handle it as the rules require.
- Record the date, the rinse and who did it.
Why three rinses and not one
Each rinse dilutes what is left on the wall. If a tote holds roughly a tenth of a percent residue and each rinse removes most of it, three rinses reduce the film far below what one long flush would. The logic is the same as washing a paint brush: several short rinses beat one long one.
The size of the tote makes the job slower. A 275 gallon bottle has dead corners near the valve and under the fill neck where rinse water does not reach by itself, so the person rinsing has to move the spray, rotate the tote on its pallet or use a lance through the top opening.
Write down how many gallons of rinse were used and where the rinsate went. That single line is the difference between a rinse that can be proved and one that cannot.
Records of a triple rinse
Write the date, the rinse liquid, the number of rinses, the volume each time and where the rinsate went. A signed line is more useful than a memory.
Rinsing outdoors
Rinsing in an open yard sends rinsate onto the ground. Use a contained wash pad or a drain connected to the right treatment, and avoid storm drains.
Questions people ask
Does a triple rinse make a tote food grade?
No. Food grade needs documented food-only history or a new bottle.
Where does the rinse water go?
It depends on what it picked up. It may be waste. Ask your waste handler.
