Chemical Waste

  1. Book your collection by filling in a Chemical waste form (Office document, 174kB)   

The specialist chemical waste contractor will then contact you with details of your collection.

General chemical guidelines

Always follow the chemical health and safety procedures and ensure your chemicals and chemical wastes are correctly stored and segregated:

  • keep flammables and oxidisers apart,
  • water reactives evolve into flammable gas – keep apart from aqueous liquids (and subsequently oxidisers),
  • acid sensitive chemicals evolve into toxic gas – keep apart from acids,
  • keep acids apart from bases,
  • chemicals with more than one hazard can be put with either category.


Ensure your chemicals and waste are correctly labelled. Download and print your own Chemical-signs-laminate (PDF, 97kB)  and Chemical-sticky-labels (PDF, 194kB) , or contact us to order some.
