You are correct!

Hazardous waste must be stored at or near the point of generation, under the control of the generator, in a compatible container and must be kept closed except when you are pouring waste into the container. There should not be a closeable door between the area where the hazardous waste was generated and the location where the hazardous waste is stored. If you have any questions, contact the Chemical Safety Office at 1-2663 for assistance.
