What do the U-listed waste codes cover?
U listings rest on toxicity, ignitability, corrosivity or reactivity. Some are listed only for ignitability, corrosivity or reactivity. Read the loss-of-characteristic exception for those.
How do I decide a U-listed waste code?
Start with the unused-product conditions. Match the chemical and any concentration limit, then check for other listings.
Which waste guides go with the U-listed waste codes?
Guides include Solvent-contaminated wipes, Waste pesticides, Laboratory chemical waste and Waste pharmaceuticals.
