• WASTE CONTAINERS MUST BE LABELED before the waste goes into them (Remember you can always change the label if the contents deviate from what you expected.)
  • EHS will supply labels; activities may use their own or utilize EHSA generated "waste label".
  • Containers of excess materials, with the manufacturers’ original label, need not be re-labeled - unless, the manufacturers’ label does not identify the contents by chemical name.  In such case the lab must appropriately label the container or provide a SDS for the material.
  • “Found” unwanted materials that have never been entered into EHSA do not need to be entered into EHSA for EHS to remove them.
  • EHS recommends using a EHSA waste label for unwanted material in original "bar-coded" containers in order to ensure that the material is removed from the lab’s inventory.  
  • Waste collection containers must be clearly labeled with the following BEFORE the waste is added:
    • The word “WASTE” in a conspicuous location.
    • The type waste being accumulated in the container, e.g., “halogenated solvent, hydrochloric acid.”
      • Generic terms that give no indication of the type hazard associated with the waste, e.g., “aqueous waste”, are not acceptable.
      • Simply writing the word “waste” on the container’s original label is not acceptable
    • Approximate amount or percentage of each constituent.
    • The date the first waste was added to the container.
  • Before the material is picked-up the following must be on the label:
    • The name and telephone number of an individual who certifies the waste container contents.
    • The actual contents of the container – provide chemical names, not abbreviations, or formulas or structural diagrams.
  • Use EHSA to generate a waste pick up request
  • Please leave at least 5% of the container space empty to allow for thermal expansion of the waste during transport and storage.
  • Containers of excess or spent oil shall be labeled “USED OIL”(see next section)
