UCLA uses the UC system-wide Waste Accumulation Storage Tracking electronically called WASTe. 

You will have 90 day from the time you make the tag to submitted it for disposal to our team.

WASTe Portal 

For information on how to generate a tag visit the following page:

How to generate a WASTe Label 

Labeling steps:
1. Generate Tag label
2. Place label in a clear envelope pouch (you can get some from our team at pick up)
3. Write the date your drop it off  on the outside of clear pouch 

What goes on your label?

• Lab/ Facility location (dropdown associated with your lab's profile) 
• Accumulation Start Date- this is the date you plan to start collecting your material
• Physical State- solid, liquid, or gas. (if your waste has visible liquid select liquid. If you have mixed waste that includes tissues see "Tissue or Specimen in Chemical Fixatives").
• Container Type- select the container type you use
• Chemical Constituents- list all the chemicals/material in your container this must equal to 100%. Please be descriptive we need to know the hazard.
• Hazard Class- select all the hazard class associated with the container
• Comments- Add any comments we need to know
• Other ID- this is any ID you may use in your lab to reference

Location:
Designate a location in your lab to store your hazardous chemical waste. This location is considered a Satellite Accumulation Area (SAA) by the EPA. Waste can only be stored for 90 days.

Refrain from storing waste under sinks. Limited quantities of waste can be stored in a fume hood as long as it does not impede functionality. Try to collected/stored your waste near the point of generation. Periodically check location(s) for conditions of waste containers for signs of leaks, corrosion or deterioration.

Maximum total amounts of waste that can be stored in an SAA:

The table above outlines the EPA limits associated with waste accumulation at your SAA. Chemical waste amounts also count towards the maximum allowable quantities (MAQs) permitted by California Fire Code (CFC). For more information about MAQs visit our resource page: 

About MAQs

Your Containers Must Be:

• Free of exterior contamination
• Labeled with a WASTe tag at all times
• Chemically compatible with the material of the storage container  (Chemical Resistance Information For Bottles, Containers & Safety Cans)
• Stored in container size suitable for the material stored, be mindful of the weight of your material don't use containers that are too big  
• Closed when not in used
• Never use cardboard

Note: Wastes stored in labware (e.g. test tubes, beakers, and flasks) and sealed with a stopper or parafilm will not be accepted.

What to do with empty chemical containers

All hazardous materials must be managed in a manner that prevents spills and uncontrolled reactions.
Stored chemicals and waste should be segregated by hazard classification. Each hazard class should have a separate secondary container.

Segregate:

• acids from bases
• flammables from oxidizers
• organic acids from inorganic acids
• oxidizers from organics
• cyanides from acids
