Hazardous chemical waste routines

The routines are updated due to new regulations and routines from The Swedish Environmetal Protection Agency and the chemical waste collectors.

• Containers can be collected in the common plastic storage. The yellow containers for contaminated materials/piercing and cutting or black containers for biological wastes are not to be used for chemical residues. 

• The container/box shall be marked with all containing components
  • Do not type Metals, Organic waste, Non halogenic organic and so on, write all components. Same goes for Hach-Lange tubes, do not only type the kit name (ie. LCK 339), type out the content on the container.

• Do not mix different Hach-Lange Kits or too many chemical compounds in the same container.
  • Each kit shall be stored in its own container. Minimize the mix of different organic or other compounds in the same container. Have several instead.

• If you have a solution that is alkaline or acidic, please take the pH on the content and type the pH on the container before putting it in the waste room.
  • This goes for all liquids like; Lugol solutions, Hach-lange Kit, Sheath fluid, Chlorine waste, Na2S waste etc. If you have a solution, please take the pH with a pH-stick (can be collected at Labservice) and write on the container. If you have the same kind of waste continuously, take the pH at several times and then you keep it in a list at your lab, then you can just add the pH on the container before you put in in the waste room.

• If you have a solution, state the solvent (water/ethanol etc.) and if possible the concentration.

• Follow the instructions in the hazardous waste room and fill in the list as instructed:

  • Don’t forget to list every chemical/compound and give each container a number!

     Write on the container;

    1. Nr (from the list)
    2. All Chemicals/compounds
    3. Concentration
    4. pH (if solution)
    5. Solvent (water/ethanol etc)

     

    Write on the list;

    1. Nr
    2. Date
    3. All Chemicals/compounds + concentration
    4. Estimated amount in container
    5. Research group
    6. Signature
