P114, Thallium(I) selenite.

  • Acute hazardousP-listed waste

    Thallium(I) selenite

P-list unused product.

Acute hazardous P-listed waste for unused thallium(I) selenite, a toxic salt of thallium & selenium.

Is P114 hazardous waste?

Yes, when the listing applies. P114 is for unused thallium(I) selenite that is thrown away, including off-specification product and qualifying residues. It is acute hazardous waste, so the stricter acute quantities apply even for a small amount.

Put P114 in Item 13 of a required hazardous waste manifest. The VSQG exemptions and empty-container rules and pharmaceutical containers have their own limits.

What does P114 cover?

It covers unused thallium(I) selenite thrown away pure, at technical grade, or in a formulation where it is the only active ingredient. It also takes in off-specification batches, residues left in nonempty containers and cleanup residues from spills of these products. Inactive ingredients don't stop it counting as the only active ingredient.

Is thallium(I) selenite waste P114 or another code?

CodeWhen it fits
P114Thrown away unused, pure or technical grade, or as the only active ingredient. Qualifying product residues count too.
Characteristic waste (D001–D043)A used chemical or a different formulation that meets a hazardous-waste characteristic. Any process listings that apply count too.

Both rows can apply at once, because a listed unused product can also have a characteristic. Having this chemical in a manufacturing waste doesn't make the waste P114. Match the waste's origin, formulation and use history. Mixing or treating listed waste generally doesn't remove the listing. That takes an exclusion, an exception or an approved delisting. The numerical and alphabetical tables give this code conflicting chemical identities. The identity and the neighbouring-code links here follow the alphabetical table, and the table entries above show the disagreement.
