Chemical WASTE - TAGS

Chemical Waste Tags: 

Everyone is responsible for making waste tags for waste they generate!

 

Here's how:

​

- go to http://wastetag.stanford.edu (don't use chrome). If you have never made a waste tag before, you will need to make a personal chem tracker account (the lab one will not work).

Enter in the information they ask for. You will probably have to look up the MSDS sheet for the chemical.

If the chemical has any flammability risk, store it in the secondary containment bin in the flammable cabinet near the waste area.

Adding a new component to an already created waste-tag:

    1. Check that the new component is compatible with the original waste.

    2. You can write in the new component with sharpie on the waste-tag OR

    3. You can go into the online system (wastetag - see above) and edit the old tag, print out a new version, and replace the old tag on the waste bottle. Do not simply ignore the orig tag and make a completely new one. This will complicate pick-up later as the orig tag was logged in the system.  Thank you!

Chemical Storage and Waste Compatibility

​

Stanford's ChemTracker database enables you to search a chemical and identify its storage group and thus which other chemicals it is compatible with! Log into ChemTracker using credentials listed below, click on the "Chem Info" tab, search your desired compound, then click "chem info" again to see storage group.

One of our most common questions is: "can I dispose of X chemical with Y chemical?"

The answer is as follows:

1. Most of our chemicals are storage group G (intrinsically uncreative) therefore can be safely combined with other G chemicals or with other storage groups in a waste container. An excellent example of this is Congo red (G) and Ethanol (L). These are compatible as waste.

2. DO NOT COMBINE STORAGE GROUPS OTHER THAN G IN DISPOSAL. For example, Bleach (E) cannot be combined in a waste container with ethanol (L) because they are in different storage groups and neither of them are G. Be aware to avoid this combination when using different cleaning products at home as bleach and alcohol create chloroform. This combination is highly toxic and can cause damage to your eyes, lungs, and liver.
