​Chemical Waste Disposal Tag

​Chemical Waste Disposal Tagging

 The Chemical Waste Disposal Tag, referred to simply as “tag”, has two portions separated at a perforated line.  Each portion has a matching number that is used for tracking the waste through processing.  These numbers should never be obscured or taped over.

When a container is created for waste, the original label of the container is defaced and mark with the word “waste”.  This is an attempt to prevent confusion about the contents.  Attach a tag to the container and write down the waste as it is added.  As new waste is created, consider the compatibility of the constituents in the waste container and the new waste (acid-base, reactives, and oxidizer-fuels) before adding them to the container.  List each waste constituent once, including any water. 

*TIP* Many labs will attach a tag and write the waste on the back of the tag as they add it.  When the container is full, they use this list to complete a new tag. 

Both the top and bottom portion of the tag must be completed.  Once completed, the lower portion should be separated from the top along the perforated line.  The contents listed on both the upper and lower should be compared to ensure both list all components in the container.  The mail the lower portion of the tag is then mailed through campus mail system to MS 4472. 

 It is important to write legibly and list all components of waste in the container.

 

PI/ Manager – the Professor or Manager responsible for the lab or shop. 

Department – academic discipline (i.e.  Biology, chemical engineering, chemistry) or shop.

Phone – please provide a phone number associated with the lab or shop.

Chemicals – list all constituents, including water.  Do not use chemical formulas or abbreviations.  Ingredients of a commercial product do not need to be listed.

Accumulation Start Date – enter the date the tag is mailed to EHS.

Building Name & No – location where the waste will be located.

Physical Property – solids suspended in liquids are usually considered liquids. The exception would be if the solid was the material of concern suspended in water.  The chemical description would be “ ______ in water”.

Quantity – select the appropriate volume or provide a weight in the space marked “Other”.  Volumes for liquids and gasses, weights for solids.  Metric units are preferred.

Container type – on “Other” please give a description (i.e. plastic, cardboard).

Reacts with – if known.

Hazards – if known.

Remarks – special instructions such as “contact before pick up” or “replacement drum needed”.
