Classification of Hazardous Waste - Routine Analysis Waste

Excess or Expired Quality Control Solutions

When classifying excess or expired quality control solutions, you must consider both the solvent and the solute.

Remember that P- or U-listed chemicals are still P- or U-listed if dissolved in water, organic solvents or acids for use as analytical standards. Subsequent dilutions are P- or U-listed as well.

Water ---- P- or U-listed, EP Toxic

Organic Solvent ---- P- or U-listed, EP Toxic, F-listed/ignitable

Acid ---- P- or U-listed, EP Toxic, Corrosive/D002
