Reusing Waste Bottles

bottlesA recent incident at the University of Rochester on October 18, 2014, reminds us about the concerns of reusing chemical waste bottles.  When reusing chemical waste bottles please make sure that the container and the material being stored in the container is compatible.  Please make sure to remember the following:

  • Waste containers must be disposed of when approximately three-quarters full.
  • Glass or polyethylene containers are recommended.  Metal cans must be used only for solvent waste that is non-corrosive.
  • Original container labels must be completely defaced or removed.
  • Waste containers must be labeled with orange ‘WASTE’ labels indicating:
              •  accumulation start date
              • pH
              • chemical names of materials added
              • location generated
              • hazards posed by the waste
  • Halogenated and Non-Halogenated waste shall be segregated from one another in separate containers.
  • Acids and Bases shall be stored in separate cabinets or areas.
  • Inorganic acids and organic waste shall be stored in separate cabinets or areas.

If you have questions concerning waste handling or storage or if you need additional orange ‘WASTE’ labels please contact Texas Tech Environmental Health & Safety at 742-3876.
