P101, Ethyl cyanide.

  • Acute hazardousP-listed waste

    Ethyl cyanide

P-list unused product.

Acute hazardous P-listed waste for unused ethyl cyanide, a flammable, toxic nitrile liquid. Propionitrile is its other name.

Is P101 hazardous waste?

Yes, when the listing applies. P101 is for unused ethyl cyanide 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 P101 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 P101 cover?

It covers unused ethyl cyanide 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 ethyl cyanide waste P101 or another code?

CodeWhen it fits
P101Thrown 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 P101. 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.
