EWC codes that commonly carry this hazard property
12 entries from the UK List of Wastes.
These are EWC entries that typically carry this hazard property, not a determination that any particular load does. Under WM3, whether a hazard property applies depends on the substances actually present and their concentrations — the producer is responsible for assessing each consignment.
- 06 01 02hydrochloric acidhazardousHydrochloric acid — corrosive, irritant and STOT (respiratory tract from HCl mist).
- 06 02 03ammonium hydroxidehazardousAmmonium hydroxide — corrosive, irritant, STOT (respiratory) and aquatic ecotoxic.
- 08 05 01waste isocyanateshazardousWaste isocyanates (TDI / MDI) — STOT (respiratory) and skin / respiratory sensitisers; classical occupational-asthma agents.
- 10 04 01slags from primary and secondary productionhazardousLead primary / secondary production slags — Pb compounds are STOT-RE, acutely toxic, carcinogenic, reprotoxic and ecotoxic.
- 10 04 02dross and skimmings from primary and secondary productionhazardousLead dross and skimmings — Pb compounds are STOT-RE, acutely toxic, carcinogenic, reprotoxic and ecotoxic.
- 10 04 04flue-gas dusthazardousLead flue-gas dust — STOT-RE, acutely toxic, carcinogenic, reprotoxic and ecotoxic.
- 10 04 05other particulates and dusthazardousOther lead particulates / dust — STOT-RE, acutely toxic, reprotoxic and ecotoxic.
- 10 04 06solid wastes from gas treatmenthazardousLead-process solid gas-treatment wastes — STOT-RE, acutely toxic, reprotoxic and ecotoxic.
- 10 04 07sludges and filter cakes from gas treatmenthazardousLead-process gas-treatment sludges — STOT-RE, acutely toxic, reprotoxic and ecotoxic.
- 13 07 01fuel oil and dieselhazardousFuel oil / diesel — flammable, aspiration toxicity, ecotoxic.
- 13 07 02petrolhazardousPetrol — highly flammable; benzene content adds acute toxicity and aspiration hazard.
- 16 01 13brake fluidshazardousBrake fluid — irritant; aspiration and STOT hazards from glycol ethers.
