Triple-rinsed IBC totes: what the grade means

Why the rinse is required

Under 40 CFR 261.7, a container that held an acute hazardous waste is empty only after triple rinsing with a solvent capable of removing the product, an equivalent cleaning, or removal of its inner liner. The rinse is a legal step, not a courtesy.

What it can become

Recycling is the common outcome. Industrial reuse is possible. A triple-rinsed tote is not food grade unless its history is documented, and a tote that held an acute hazardous waste almost never has one. Triple rinsing, step by step has the procedure and the record to keep.

What to send

The SDS, the rinse record and the heel. The rinse liquid itself may be a waste; the generator handles it.

The rule in plain words

A container that held an acute hazardous waste is not empty just because it is drained. 40 CFR 261.7(b)(3) requires triple rinsing with a solvent capable of removing the product, or an equivalent cleaning method, or removal of the inner liner. Only then does the tote stop being a hazardous waste container.

The grade exists because that process is a legal event that someone must record. A triple-rinsed tote with no record of the three rinses is a tote with a claim, not a grade.

The record that goes with it

1. The date of each rinse.
2. The solvent used and its quantity.
3. The product that was in the tote.
4. Who did the rinsing.
5. Where the rinsate went.

Keep the note with the tote. A buyer or a recycler will ask for it, and so will an inspector.

Still the original bottle

Three rinses make the tote legally empty. They do not make it food grade, they do not update the plate and they do not undo the stain a strong product may have left. That is why the usual next life is recycling, with industrial reuse as the rarer alternative.

The triple-rinse guide gives the sequence in order.

Why this grade is the most documented

Every other grade can be assessed by looking at the tote. This one cannot, because the event that makes it empty leaves no mark. The record is the grade. A buyer, a recycler and an inspector will all ask to see it, and a tote that has no record is treated as one that was never rinsed.

A short example record

A usable record fits on one line: the date, the product, the solvent, the three rinse volumes and the initials of the person who did it. A line like that, kept with the tote, answers the first question an inspector or a buyer will ask.

Where a triple-rinsed tote goes next

Most go to recycling, since the bottle is the original and may be stained. A few go to industrial reuse where the old product does not matter. None is described as food grade. The record is attached to the tote or to the request.
