New Carboy Inventory Form for Dump-Jug Waste

It is extremely important that EHS personnel know all of the chemical constituents in a waste container in order to make accurate determinations for safe, compliant handling and disposal. Sometimes while working in the lab, it is difficult to keep track of all of the chemicals that get poured into a carboy. To assist with this, a new form has been developed to keep track of the chemicals going into dump jugs.


The form will be folded and placed in the handle of dump jugs when EHS Environmental Technicians drop empty containers in the lab. There will be a clear, plastic packing slip envelope attached to one side of the jug so that once full, you can place the completed form into it before disposal. As you fill the jug, you can place the inventory form on a clipboard (or other convenient method) near the container to make it easy to complete.


Meanwhile, your container will also need to have our regular, white Waste Chemical label on the front. This label must also be completed with a description that identifies the waste, such as “HPLC Waste Solvents” for example. This fulfills the EPA requirement that your waste be labeled in a manner that identifies the container contents. Information on the waste chemical label can be brief, but must not contain abbreviations or vague descriptions such as just the word “Waste”. Follow your waste description with “See inventory sheet” to indicate there is also an inventory with detailed information belonging to the container.


Ensure that the waste name on the label and the waste name on the inventory form are the same, so that you can match the correct form with the correct dump jug. An example of a completed waste chemical label and inventory form are shown below in Figure 1.

A few more things to bear in mind when it comes to dump-jug waste.

  • Keep wastes generated from separate processes in separate waste containers, unless the wastes are similar in composition and compatible with each other.
    • Don’t mix organics with oxidizers or acids with bases
  • Keep chemicals that have a strong odor out of mixed waste dump-jugs whenever possible.  Dispose of “stinky” waste in the smallest volumes possible.
  • Keep heavy metals (arsenic, barium, cadmium, chromium, lead, mercury, silver) and halogens out of solvent waste when feasible.
  • Dispose of full containers in a timely manner.  If a container is not full because it is too large for the volume of waste generated, or a process has ended or changed, dispose of the waste and request a smaller container.  Or, let us know you no longer need a waste jug.
