U211, Carbon tetrachloride.

  • U-listed waste

    Carbon tetrachloride

U-list unused product.

Toxic U-listed hazardous waste for unused carbon tetrachloride, a chlorinated solvent once used in fire extinguishers.

Is U211 hazardous waste?

Yes, when the listing applies. U211 is a U-listed hazardous waste for unused carbon tetrachloride that is thrown away, including off-specification product and qualifying residues. It is nonacute, not an acute P-listed waste. The listing depends on the product and how it is discarded, not on a TCLP result alone.

On a required hazardous waste manifest, put U211 in Item 13. Also read VSQG exemptions and empty-container rules and pharmaceutical containers.

What does U211 cover?

This listing covers unused carbon tetrachloride thrown away as pure or technical grade, or in a product where it is the only active ingredient. That includes off-specification batches, residues left in nonempty containers and spill cleanup residues. Inactive ingredients don't change that.

Is carbon tetrachloride waste always U211?

CodeWhen it fits
U211The unused chemical is discarded as pure or technical grade, or as the sole active ingredient. Qualifying product residues count too.
D019The waste’s TCLP extract holds carbon tetrachloride at 0.5 mg/L or more. The product listing can apply too.
F001It is spent after use in degreasing, or is a still bottom from recovering that degreasing solvent.
Characteristic waste (D001–D043)A used chemical or a different formulation meets a hazardous-waste characteristic. Assess any process listings that apply too.

A listed unused product can also exhibit a characteristic, so more than one row can apply. Having this chemical in a manufacturing waste doesn't make the waste U211. Match the waste’s origin, formulation and use history. Mixing listed waste with solid waste, or treating it, generally doesn't remove the listing. It takes an applicable exclusion, exception or approved delisting.

Which wastes take U211?

WasteWhen it’s U211
Laboratory chemical wasteThe discarded reagent meets unused-product conditions as a pure, technical-grade or sole-active-ingredient product
Unused carbon tetrachlorideThe discarded commercial chemical product is pure or technical-grade carbon tetrachloride, or carbon tetrachloride is its sole active ingredient
