Unlabeled Beaker in Hood

Incident Overview: 

A large (1000 mL) beaker of mixed chemicals was left in a hood without any labeling of chemical ID or contact information for the user.

Root Cause: 

A lack of the proper disposal container (of correct type and size) caused the lab user to leave the chemicals in the hood instead of disposing of them. A note had originally been left with the chemicals, however, it disappeared while the unlabeled waste remained.

Preventative Actions: 

The best action would have been prior to mixing the chemicals, a waste container should have been located and been available to ensure proper disposal of the waste directly after it was used. However, at a minimum, a chemical sticky note label should have been filled out with the beaker contents identified and contact information for the lab user, and placed directly on the beaker until a proper waste container was obtained.
