Environmental Health and Safety strongly encourages the containment of all chemical waste within laboratory facilities. For instances where lab personnel are infrequently present, a chemical waste pickup request must be submitted before it is permissible to temporarily store the chemicals in the hallway.
These containers must be securely closed and appropriately labeled to indicate the contents with the waste request number affixed on the outside of the container. Containers with a capacity of less than 5 gallons, as well as any glass containers, must be placed within suitable secondary containment, such as a plastic tote.
Please note: Cardboard boxes are not considered appropriate secondary containment for chemical waste.
