WM3 Technical Guidance

WM3 Technical Guidance

WM3 introduces a whole raft of changes, mainly associated with the Classification, Labelling and Packaging Regulation (CLP) (2008/1272/EC) which includes a new system of chemical classification based on hazard classes, categories and statement codes rather than the previous risk phrases and categories of danger used in WM2. The full Document can be found here.

How the changes may affect us

All hazardous wastes must be re-assessed under the new criteria. This may result in some wastes that were previously none hazardous being classified as hazardous. Wastes will also have a new code.

  • Previously none hazardous waste being classified as hazardous.

WM3 may result in some wastes that were previously none hazardous being classified as hazardous.

For example packaging that cannot be proven to be free of any residue or contamination from hazardous substance has to be classified and treated as hazardous waste. Any packaging that has contained a hazardous product and has not been decontaminated by an approved method (with appropriate treatment of the decontamination residues), is to be automatically considered hazardous in nature, regardless of its weight or concentration of the hazardous substance originally contained in the packaging.

  • WM3 New Waste Coding System

Hazardous Codes have been replaced with Hazardous Property Codes. Some HP codes differ from WM2, so WM3 should be referred to for guidance on HP codes.

Paperwork, for example Hazardous Waste Consignment Notes, needs to show the correct code.
